Blending similar colours into a solid colour?

I've scanned a map (actually a nautical chart) that I want to print; see link below to a very small portion of the RGB 8-bit/Chan image.
http://i77.photobucket.com/albums/j54/nigelmercier/sample_zps69cffb91.png~original
In this I can identify white, yellow, cyan, light-cyan green, dark-green, black, red, red+cyan, red+green... The main image has a few more.
The large areas of colour have a mottled appearance, where there is a variation. I've used Smart Blur to reduce this considerably, but I'd like to impove it if possible. Is there a way to remove the colour variations? I've tried posterising, but it is too agressive, and I would need to adjust the cut-off points.

Just off the top of my head: You might try a very careful use of Select > Color Range, Feather the edges a bit (to try and avoid the posterizing effect), and then replace the selection with a solid color.
Just be careful that Color Range doesn't grab close-color objects you don't want to change.

How to prevent from inserting two similar values into DB?

Hi,
I wanted to know how we can prevent from inseting two similar values into the database, e.g the user id which should be unique. Here is some sample code, Please help me.
String s10 = req.getParameter("T10");
String s11 = req.getParameter("T11");
rs = st.executeQuery("select * from Register where userid='"+s10+"' ");
if(rs.next())
sos.println("Sorry the user already exists");
else
int x = st.executeUpdate("insert into Register values('"+s1+"','"+s2+"','"+s3+"','"+s4+"','"+s5+"',"+s6+","+s7+",'"+s8+"','"+s9+"','"+s10+"','"+s11+"')");
Thaks in advance
Uma

Hi reddy
Your code works will be perfect with slight changes whucah are as below:
String s10 = req.getParameter("T10");
String s11 = req.getParameter("T11");
rs = st.executeQuery("select * from Register where upper(userid)='"+s10.toUpperCase()+"' ");
if(rs.next())
sos.println("Sorry the user already exists");
else
int x = st.executeUpdate("insert into Register values('"+s1+"','"+s2+"','"+s3+"','"+s4+"','"+s5+"',"+s6+","+s7+",'"+s8+"','"+s9+"','"+s10+"','"+s11+"')");
In the above Query we will get a unique userids it may be smallcase or Uppercase
This will help u

Sort similar data into columns

I have a data set something liek this:
1 2 3 4 5
3 4 5
2 3 4 5
2 5
What I would like to be able to do is find a simple way of putting all the similar values into 1 column, like the following:
1 2 3 4 5
0 0 3 4 5
0 2 3 4 5
0 2 0 0 5
In my code I am not actually trying to match exact numbers, I am trying to put in columns numbers that are a few decimal places apart, so numbers like 5.1, 5.2 and 5.3 would be in a single column. Anyone know an easy way to do this?

If I have a 2d array where each row contains the values of peaks positions for a particular graph, then the max width of the array is the length of the array which contains the most peaks. As for the height, I have 360 graphs, so their are 360 rows. Basically I have 360 graphs, where each graph represents the acoustic reflection of an object at 1 degree increments. What I am trying to do is track the changes of specific peaks, however their position moves around a bit so I need a way of lining these peaks up again so I can do a useful analysis. So basically what I do is use the labview peak extractor on each signal, and store the peak positions for each angle in a 2d array. Now I just want to line the data up. For example peak 1 might start at bin 5, then in the next graph jump to bin 5.1 and so on. Peak 2 might start at bin 12 then might jump to bin 12.1, then 12.2. So then I should have something like follows.
5.1 12
5.2 12.1
5.3 12.2
However when I have data like this:
1 2 5.1 7 12
0 0 5.2 12.1
0 0 5.3 8 12.2
I am finding it diffult to work out a way to do this.I havent really got any code written for this either that you might be able to lookover, because I dontreally know where to start.
The bit highlighted in red is the assumption you have made that is wrong. If the peaks are at different points you have a problem...
What you need to do is create a mega array of all the data points and find out how wide that would be:
e.g
1,2,4
1,2,4.5
these would still combine to make an array of 3 columns as all of the columns have the same data values.
1,2,3
1,2,4
these would combine to make an array of 4 columns (3 in IT speak and if indexing). The columns would be 1,2,3,4
If you have too much data to add together into 1 mega array and get the overall width first, the ther are other ways of doing it, I'm just pointing you at the simplest to implement. The other ways require more thought and debugging. (Think outside the box once you can see the problem).

Keying video that has similar colour background, advice please-image included.

Last-year I visited America, and on the last day managed to secure an interview with a WW2 Ace, which had to be done within a very short time span.
Unfortunately this left me with a situation that I couldn't really control, and so I am in a situation where I need to add a background to footage (doesn't need to be perfect, so a fringe would be acceptable), but I wonder if anyone can give me steps on how to best remove the Pilot from the plain background.
An image can be seen here from the footage:
http://www.atgo72.dsl.pipex.com/key.jpg
As you can see, his shirt and hair are very similar to the background colour, so I have had difficulty colour and chroma-keying.
I am wondering if it is possible to key him out of the background, or whether I'm chasing my own tail?
Any help would be much appreciated, cheers, Neil.

Here is my feeble attempt.
http://img135.imageshack.us/img135/3345/keyout.png
How: create a simple travelling mask and keyframe the movement of person try avoiding too few bezier points for easier, this is helpful for keying purposes so that the keyer has less areas to key out and in the end you can additionaly adjust mask expansion and feather at your needs >> Keying: i used at least 4 instances of color key and play around with color, color tolerance and feather of each instance >> add matte choker, adjust >> ad simple choker, adjust.
NOTE: Ae does not update changes very well, means every slider adjustment must be done by little increments, so adjust a little, release, adjust, release, to get the preview done this is pretty awful but it works somehow.
COMP PREVIEW MUST BE SET @ FULL QUALITY otherwise at half resolution results vary very heavy - thats the next flaw, hopefully better in CS5
much luck.

Issue with blend mode colour dodge?

So I'm not all that new to photoshop, I'd probably put myself in the intermediate category, but for some reason I haven't been able to figure this issue out, and I would love some help. I was doing a tutorial, and it mentioned we needed to change the blend mode of our photo to color dodge. I found color dodge fine, but for some reason when I tried to apply it, nothing happened. The tutorial mentioned grouping the layers, which I did, still no change.
So I found another tutorial that broke the process down, but I've still been unable to apply color dodge to what I'm working on. When I did apply colour dodge, I got this:
I have no idea what to do about the red circle. I'm sure this is a totally ridiculous error, but I'd love some help!
Here's what I'm attempting to change, with no success:
Here's the picture I would ultimately like to apply colour dodge to:
Again, I'm sure this is really simple, but I haven't found an easy answer, so any help would be appreciated!
Thanks!

What you expect to happen after applying Color Dodge? With Blue Fill layer on top and white pixels beneath, applying Color Dodge will produce what you see on your screen. Same will happen if you move layer with white pixels on top of layer with blue fill color. There is some mistake in tutorial.

Similar channel into single channel

Dear All,
Is there any way to merge the multiple similar channel to single channel without flattening layers.
If pantone reflex blue 3 times is there means i need to merge it into single reflex blue channel.
Pls help..
Thank you,
Joe

Yes spot channel only and in Same document itself.
And the above script need to run in Extend tool script?. Coz by this script there is no changes happening.
By using Apply image can merge only two channels at a time. And after merged into a single channel source channel also remains.
For ex, Pantone Reflex Blue 1
Pantone Reflex Blue 2
Now i need to merge into 1. so after Merging by using Apply image
Pantone Reflex Blue 1 2
Pantone Reflex Blue 2 (But this is to be automatically deleted after merging, which is not possible by using Apply image)
By using the script this needs to be recover
1) In channel options
Color indicates - Spot Color
Color - Reflex Blue
Solidity - 0%
In same way i have taken the separation in different area of my image with same spot color.
2) If process color are taken as spot channel that also need to merge with process channel (CMYK)
Color indicates - Spot color
Color - C100%
Solidity - 0%
If this is option selected in this channel to be merge with Cyan process color channel.
By using Apply image option i used to give Multiply only and Opacity to 100%. Same need to apply this script. Pls help..
Thank you,
Joe

Why do we put similar infoobjects into single dimension.

Why do we put similar infoobjects(Char ex: 0material, 0matl_type, 0matl_group, 0matl_cat, 0mat_plant) into single dimension(MATERIAL DIMENSION). and other similar like(0CUSTOMER, 0SHIP_STCK, 0SOLD_TO, 0DIVISION, ZORD_MAT) into single dimension(CUSTOMER DIMENSION), What will happen if i put all these infoobjects into single Dimension, Can some one answer me in the system prospect, data base prospect as well as performace point of view or may in general.
Points will be given.............. thats what u definitely deserve for a right answer.

Santosh,
This is an important thing while deciding upon the dimensions. Its not the similar things we are putting together but based on the data realtion and cardinality we put the chars in a dimension. If dimensions are not properly designed the tables size increases drastically and lead to poor performance. Taking an example the relation between the chars in a dimension should be 1:m and not n:m. A material can have one material type and belons to one materila group for a plant is the relation which is a 1:n relation. Chars with high cardinality are put in separate dimensions instead of grouping with other chars.
The grouping of classification groups (characteristics) whose content is logically connected, under a single generic term. If the dimension contains a characteristic whose value already uniquely determines the values of all other characteristics from a business-orientated viewpoint, then the dimension is named after this characteristic.

Blending Images Backgrounds Into Theme Background

Hey. I've used Powerpoint before, and even old versions of Powerpoint have the feature to blend in the background of an image that I've pasted into the slide into the background of my theme. How would I do it in Keynote?

Just drag and drop the picture into the slide. Position it where ever you want the picture (ie. take up the entire background or just a certain area, etc.). Then click on the Graphic tab on the inspector. At the bottom is a scroll bar that allows you to modify the opacity of the picture. You can then fade it out to achieve the style of background you want. Hope this helps.

Blending an image into a background - hue/saturation grayed out

Thanks for your help. I am trying to blend an image to a background as is illustrated in this video:
http://www.youtube.com/watch?v=xSehcaWFBVM
Rather than using the overlay tool, the lady in the video suggests using the ‘hue and saturation’ option to blend the photo with the background. I get all the way to this step, but then the ‘hue and saturation’ option (and pretty much all of the options under image – adjustments are grayed out. The ‘modes’ for both the background and the photo are the same (RGB and 8bit). I have been at this for hours (>4) and I cannot get past this step. I would be extremely grateful for some help as to how I might ‘free up’ the adjustment options and have this photo look similar to that showed in the video.
Thanks.

CLUB similar items into single item

In 0PROFIT_CTR, I have values like
555, 555_US, 555_CA, 555_MX
777,777_US, 777_CA,777_MX
In my BEX output, I need to show all 555 series as 555 and 777 series as 777
What is the best way to do it.
Thanks

Hi Jagannadha,
In transformation level, write this field routine in your 0PROFIT_CTR:
RESULT = SOURCE_FIELDS-PROFIT_CTR(3).
So that you will only get the first 3 characters of your PROFIT_CTR..Then in reporting you will have the all 555 series combined as 555..
OR
If your PROFIT_CTR is keyfield, you create an object similar to your PROFIT_CTR (let's call it ZPRFT_CTR) and do the routine above in the new object..Using this, your original data in PROFIT_CTR will be retained..
Then in your query designer, you use the ZPRFT_CTR to be able to get all 555 series as 555..
Regards,
Loed

Beginner at photoshop: how to fade one edge on photo into a solid graphic bar

I am creating a banner with a photo on the left and I want the edge of the photo to extend to the left and fade from photo to solid graphic bar. I will then be writing text in the color bar for the banner. Does anyone know how to do this? Thanks!

Make sure your picture is in a layer above the background color. With your picture layer selected (as you can see by the blue highlight in the layers panel), click the mask button (bottom red circle). Then, with the mask selected (see the black stroke around it's icon in the top red circle; it is selected by default), use the gradient tool to paint the mask white to black. White reveals, black conceals. If you need to edit the picture layer, you can click the layer icon (just to the left of the mask icon in the top red circle). If you click the chain icon connecting mask and layer, you can scale/move them independently. Click back where the chain was to re-link them.

How to group Similar Rows into One Row ?? Suggestions??

Hi there , I am having a problem in my project you see I have 2 dimensions in my cube called Username and Symbols and a measure called M1.
You see in the Symbol dimension there is repeated data in multiple rows such as the following
Pepsi
Pepsi
Pepsi
CocalCola
Now when i display the dimension Username with the dimension Symbol using the Measure value M1. I get something like this
UserName A
Pepsi---- 10
Pepsi---- 10
Pepsi---- 10
CoacalCola--- 20
Now in the above table UserNameA represents a member of Username Dimension and cold drinks represent members of the Symbol Dimension
and the numarical value represents the measure M1.
I want it to appear something like this
UserName A
Pepsi 30 (Notice The measures of Pepsi have been added)
CocalCola 20
Any idea on how i can accomplish this or tip i would be really thankful

Hi
Use the aggregator operator in mapping. You can use the SUM function on the columns you wish to sum for example, and group by the other columns.

How do I get a three-way colour blend (and rounded edge effect)?

For what it's worth I'm using Illustrator CS5 but I imagine any solution will apply to all recent versions.
In practice I've pretty much got where I need to so this isn't an immediate problem, but I'm sure there are much better ways of achieving the effect and I'd like to have them in stock for future reference. I'm not sure if this is a basic matter that I should be able to figure out easily or a challenge for more advanced practitioners; either way, I'd be grateful for any suggestions.
The end product I was after - sort of - is shown here:
The two elements I struggled with were:
Blending the colours where they join - particularly the three-way blend at the middle, which in the end I avoided by placing another object on top! I resorted to a manual, tedious and inaccurate point-by-point approach using meshes and it didn't really deliver what I wanted, which was a seamless join between the colours.
Getting the effect of a rounded edge at the perimeter of the triangle - I used the same mesh-and-guesswork technique (and it shows).
In whatever solution anyone can suggest, one of the important things is to be able to dictate the distance over which the blend and shading operate, both where the colours merge and at the rounded edges. Feel free, by the way, to start from the very beginning with "First, construct your triangle" - I realised, as I did this, that there are a many different ways to do that, and one may be better than another for a particular blending approach.
Thanks for your thoughts,
Giles.

1. Polygon Tool: ShiftDrag to draw a triangle oriented with one of its corners at the top.
2. Apply a linear grad fill, blue to white, -90°
3. Appearance palette: Add New Fill. Linear grad, red to white, 30°
4. Appearance palette: Add New Fill. Linear grad, green to white, 150°
5 Appearance palette: Select each fill. Set its Transparency Mode to Exclusion.
6.Deselect. Select the path. Effect>Distort>RoundedCorners.
