Finding objects in an image
I am trying to make an OCR program. The text I'm trying to OCR isn't in lines. Each character is in a random place in the image. I have the OCR part working, but I am having trouble locating the characters in the image. How can I quickly separate each character in the image?

Algorithm to find the area and color of the objects in an image
Hello everyone,
I have some problems in finding the segmented objects once i find the threshold , i want to find the area of the objects in the image . for example i have some lymphocytes in the image and i need to seperate them from the background by labelling them. can i seperate them by using the colour as well . please give some idea .
my code till now is:
int data = -1;
try {
System.out.println("Is the input a FloatImage ?");
m_fi_in = (FloatImage)inputData[0];
data = 0;
catch (ClassCastException cce) {

data = 1;
catch (ClassCastException cce2) {

data = -1;
System.out.println(data);
// For the FloatImage
if (data == 0) {
// For the Volume
else if(data == 1) {
System.out.println("Entering Volume for segmentation....");
// Get target dimensions
int depth = m_vol_in.getDepth();

Find Object.vi function of 3D picture control - when object not found
I am using Labview 8.2, and this post is regarding the 3D Picture Control.
I am wanting to make use of the "Find Object" VI to either return a reference to a named object, or otherwise determine that it does not exist yet. However, if I call it with the name of an object that doesn't exist yet (i.e. just any random string), it returns an error message that arises from the attempt to release a queue (the reference to which gets lost when crossing a zero-iteration For Loop's tunnels), instead of an error message that says "Object not found" which I would find much more useful. With a simple modification of the "Find Object.vi" function, this behaviour can be changed, by replacing the For Loop's tunnels with shift registers.
The problem with the current function is that the error is not an intentionally thrown error, rather just the result of the queue's refnum being set to the default 0 as it "exits" the For Loop, since in the situation that an object is not found, the code passes a 0 to the N terminal.
The attached images show the problematic code and the simple modification

I agree with you - the current way of handling the case of an object not being found does not appear to be ideal.
This was reported to R&D (# 43D8GSVQ) for further investigation.
Thanks for the feedback!

That is why I labeled it with Finder Object reference won’t return POSIX path, because I tried what was suggested about using the POSIX path of line. I thought seeing the lines above and around it would help set the context.
So I need those files, but I need them sorted by creation date so that they’re in that order for the next renaming step. -
In my Macbook Pro, the Finder folder has duplicate images in the 'all images' file. One image is small and the other is full size. First question is why do I have two of every image? Why is one small and the other large. Do I need two of everything? If not, which do I delete?

Re: duplicate images in finder.
Nearly all images are JPG with a few GIF and PNG sprinkled in.
I opened the inspector so I do get info when opening each image, but it a slow process.
It seems that one image is around 70k while its twin can be up to 4Mb which is what comes unedited from my camera. Sometimes there will be 3 or 4 identical images in finder, but when I open iPhoto to see what ‘s really in the file, I find only one image, and it’s full sized.
Are all these extra images, even if they are aliases, taking up space on my drive? And should I delete them? The info bar says I have over 10,000 images, which is rather a lot for what I do.
I am unable to add the file size on the view menu as it is grayed out. Don’t know why it’s gray, but having that info on the screen would save a lot of time and fiddling with each image.
I am trying to resize selected pix so I can upload them to e-bay, which requires less than 70k. I have looked at resizing programs but most are for PC platform and not Mac, so I am trying to resize in the finder window under tools. Tedious at best. Any suggestions will be appreciated
Thanks for your help,

How can you find out an individual image size from multiple images on a canvas
This is probably a really really simple question but I can't for the life of me find how I can find out an individual image size from multiple images on a canvas. eg I have 3 photos i want to arrange 1 large and the other two next to it half the size. How can I edit individual image size on the canvas as when I select the image on a sperate layer I want to resize it just resizes the entire canvas and not the individual image
ThanksI want to know they exact dimensions though. You can get them by dragging to the 0,0 corner and then reading off of the ruler scale on the sides but its fiddily as you have to zoom right in and work it out. I know in photoshop there is a ruler but is there any other way in Elements?
-
As I can sometimes do, I did not read the directions before delving into LR. Now I find my self with image history in LR on 2 or 3 of my HD's. I would like to now consolidate it on one HD but fear in doing so I will lose the images I have created within LR. Is there a tutorio or some other way to get me back on track with this application?
Your image history (if I understand you properly) is stored in your catalog file, and nowhere else, and so it is only on a single drive.
Do you mean you have edited photos on multiple drives? This isn't a problem for Lightroom at all, the software doesn't care, and you can leave things just the way they are. But if it bothers you for some reason, you can move the photos to a single drive if you want. In Lightroom select the desired photos or folders (it's easier to do this using Folders) and drag them to the desired drive.
Alternative if you will be moving lots of folders: Adobe Lightroom - Find moved or missing files and folders -
How do I take an object from an image and save it so I can use it in other images?
I am trying to figure out how to take an object from an image and save it so I can re-use it again in other pictures? I know how to use the magic wand to select the object and place it in a blank image.... but I do not know how to re size the selected object or keep it for later use. Basically I would like to use the object the same way that I use the graphics ... so I guess I am wondering if there is a way that I can make my own graphics... I have Elements Photoshop 13. Thanks for any help/advice.... Jerrie
Hi Jerrie,
You can re-size using Transformation tool. Ctrl + T will give you a box to re-size the image or object.
You can save these object as PNG file with Transparent layer. You can use these objects later in another projects.

Render a swf object(contains an image) in navigator not possible
Hy, I have a swf object that is an image(a circle). I have tried to render it in firefox but it doesnt render anything but I have tried with other swf object(not an image, an application) and it renders it ok. So can I render a swf file that is an image or is not possible? should I extract the image in it first to render on the navigator?
ThanksTake a look at
http://developers.sun.com/jscreator/learning/tutorials
/2/file_upload.html#07.Thanks jetsons. That particular code sample (#7 in SJSC, #8 in Netbeans) shows only how to serialize a file to a different location on the server, not how to reference a file (not stored within the app forlder) to be rendered as a result of hyperlink click for example. Reading a little further in that page, it says:
Be careful when putting the uploaded files in the web application as anyone can access the files by URL, such as http://localhost:29080/MyWebApplication/faces/upload/images/myPicture.gif.
So, I am thinking that for added security, may be it is meant to be that I can't make an imageComponent reference a file outside of the wep app folder, but I am just guessing. In which case, I will simply have to store all such files within the web app folder before attempting to access them, unless someone has a better answer. -
Need help for finding objects impacted by size change for an infoobject
hi all,
need help for finding objects impacted by size change
for xxx infoobject, due to some requirements, the size to be changed from
char(4) to char(10), in the source database tables as well as adjustment
to be done in BI side.
this infoobject xxx is nav attribute of YYY as well as for WWW
infoobjects. and xxx is loaded from infopkg for www infoobject load.
now that i have to prepare an impact analysis doc for BI side.
pls help me with what all could be impacted and what to be done as a
solution to implement the size change.
FYI:
where used list for xxx infoobject - relveals these object types :
infocubes,
infosources,
tranfer rules,
DSO.
attribute of characteristic,
nav attribute,
ref infoobject,
in queries,
in variablesHi Swetha,
You will have to manually make the table adjustments in all the systems using SE14 trans since the changes done using SE14 cannot be collected in any TR.
How to adjust tables :
Enter the table name in SE14. For ex for any Z master data(Say ZABCD), master data table name would be /BIC/PZABCD, text table would be /BIC/TZABCD. Similarly any DSO(say ZXYZ) table name would be /BIC/AZXYZ00 etc.
Just enter the table name in SE14 trans --> Edit --> Select the radio button "Save Data" --> Click on Activate & adjust database table.
NOTE : Be very careful in using SE14 trans since there is possibility that the backend table could be deleted.
How to collect the changes in TR:
You can collect only the changes made to the IO --> When you activate, it will ask you for the TR --> Enter the correct package name & create a new TR. If it doesn't prompt you for TR, just goto Extras --> Write transport request from the IO properties Menu screen. Once these IO changes are moved successfully, then the above proceduce can be followed using SE14 trans.
Hope it helps!

I have 10,000 images & documents(if you click on the finder icon & go to images or documents) on my computer - my question is: can I delete these? Some I do not know how they got there.
Or do I just leave them alone. Some of the documents are gobeldy goop!

DawneUnless you have a space problem, leave them. Only delete stuff when you know what it is, and are sure you don't need it.

3D Picture Control: Find Object function closes scene reference when it has no children
I am using Labview 8.2
The "Find Object.vi" function is causing me some problems as it is closing the reference to the Scene Object passed into it when that Scene object does not contain any child objects. The attached screengrab shows the relevant part of the "Find Object.vi" function - the input (parent) reference is added to the front of the queue, and if the "ObjectCount" method returns 0, then the reference is closed (and hence unavailable from that point on. By removing the "Close Reference" function, the reference remains valid, but I am unsure of what other consequences this would have (and I don't like editing NI VI's!).
I have attached an example VI to illustrate this, hopefully it is clear enough what is happening. Basically, I want to be able to check for the existence of a child object without risking losing the parent object's reference. I could always write my own but perhaps the "Find Object.vi" function is incorrect?
Attachments:
Find Object Testing.vi 30 KB
Find Object_closingreference.png 5 KBpauldavey,
I agree with you again that the behavior of "Find Object.vi" does not appear to be optimal. It is almost as if it should be called "Select Object.vi" as it doesn't appear to be handling the case in which no objects are found very well.
The help file states that it:
Takes a 3D scene reference
and an object name and returns the first object in the scene with a matching
name.
As it's behavior is not defined for the event that a matching object is not found I would recommend writing your own VI to perform the function you need.
I plan on looking a little further into this and I may end up filing a CAR for this behavior too.
We appreciate the feedback and I apologize for the difficulties this VI is causing you.

Easiest way to find time machine files is to open up the folder or application(works for email and iphoto) they were in - then click on time machine ICON or enter time machine from the time machine menu to go back through the files.

Finder doesn't show image dimensions
Hi!
I have a problem with image dimensions in Finder. Finder doesn't show image dimension info in preview column and Get Info window. But when I open in Preview app I can see dimensions in Get Info window. How to solve this problem. If I want to sort images by dimension, I can't do that. Because Finder doesn't know image dimensions. You can see images below.Terence Devlin wrote:
That's because the Finder is a file manager and works from file metadata. The data you're seeking is about the file contents. You need to use a Photo Manager or Browser.
There is someone who can sort images by dimensions and see dimensions in list view. Also if Finder will not show image dimensions, why give me "Dimensions" and "Resolution" option to select in list view.

Launch a Finder window. Press command+J, and set Show Item Info. Now the image dimensions will show below each image icon. If it is a movie, then the duration of the movie is shown.
I have done this. But doesn't show information.
