Detect overlay of image

I want to make an action game. But it seems that is important to detect whether the images touch another.
So, are there any methods in java or any other better way to do that?

What you are describing is called "collision detection".
The web is filled with examples on how to do it.
So just google yourself silly.

Detecting object in images

Hi,
how can I detect objects in images using java ?
I need to detect movements of an object in consecutive images exported from a video.
thank you

use PixelGrabber to record a grid of colors then store it in a 2D array and with the next image get another 2D array of colors from the picture and compare the two arrays to see which part of the grid changed. You still will not have a way to tell the difference from the place were the object was and the color of the current object unless you had a image of the place room screen or what ever it is without objects and compared all other images to that one.

How do I hide the stacks badge overlays on images in the browser?

In View > Metadata Display > Show metadata is off, but the badge (with the number in the stack) is still visible.

On
http://documentation.apple.com/en/aperture/usermanual/index.html#chapter=11%26se ction=9%26tasks=true
is explained how to show them;
To display badge overlays on images in the Browser in grid view
Do one of the following:The Browser & Viewer Metadata dialog appears.
Choose View > Metadata Display > Customize (or press Command-J).
In the tool strip, choose Edit from the Metadata Overlays pop-up menu.
Choose a Browser Grid View metadata overlay view from the View pop-up menu.
In the Metadata Fields column, click the Aperture disclosure triangle to reveal the metadata fields below it, then select the Badges checkbox.
Click OK.
Make sure both Show Metadata and the metadata overlay view you just modified are selected for the Browser in the Metadata Overlays pop-up menu in the tool strip.
Badge overlays are now visible in the Browser.
You can turn off the display of badge overlays in the Browser by turning off the display of metadata. For more information, see Turning the Display of Metadata On or Off.
But I don't understand; In the tool strip, choose Edit from the Metadata Overlays pop-up menu.

Why my image acquisition pci 1409 board could not be detected by matlab image acquisition toolbox?

i have a National Instruments PCI-1409 image acquisition board that works very well
with the software provided by National Instruments, whereas it could
not be detected by matlab image acquisition toolbox when the command
"imaqhwinfo" was executed. I don't know why. the system is XP and
DirectX9.
any of your advice will be greatly appreciated.
thanks
yours sincerely

Is your matlab image acquisition toolbox DirectX based? If so, NI frame grabber will not work for your matlab image acquisition toolbox because it does not provide WDM or VFW drivers.

How indesign detects that the images have been modified

Hello,
My problem is that all my images links are seen modified (yellow triangle) while the images don't have been modified.
The modified dates are the same.
All my images are on a unix server and indesign is used on Mac.
How indesign detects that the images have been modified ?

Thank you for your answer.
When you say the time stamp you talk about the modification date in the box link info ?
Because this date is the same on the image and in indesign and when I update the image this date doesn't change.
the only informations that change when I update the links are the import date and the state (modified become ok)

How to show the ellipse found in the IMAQ shape detect to the image

I have come out with the VI which had detected the ellipses. The ellipse result shown in the last part just only shows the number of matches and also the ellipses information. The problem is I wanted the ellipse found shown in the image to show where is the ellipse that detected in the LABVIEW but not only showing me the number of ellipse detected. Because I wanted to know the ellipse detected in the image provided that other shape is also in the image. Sorry for the bad English maybe I don't know use English to state my question correctly. Thank you for the helping I stuck in the last part to complete my task.
PS: I have attach my VI and image that I used in below. The minimum score set it to 990 and it will show the result of 3 numbers of matches. Anyone know how to locate the 3 ellipse in the image? Thank you for the help

Overlay one image over another one.

Hi,
I am trying to overlay one image over another one.
(example ..
First images 1) This will have complete picture like the passport picture with background
Second Image 2) This will have some specific parts(background of above) whitened
Result picture 3) This should have the passport picture with out any background just the person.
Is this possible using intermedia ??
Thanks in advance.

dude, not too sure the dept. of homeland security is going to be cool with doing that.
unless you can make me a passport from Guam.

Automated way to overlay one image over multiple images from a folder?

I need to overlay a transparent image of a tablet over about 50 images from a folder - is there any automated way to do this? I can use either Photoshop or Illustrator
Thanks
Jamie

Have you tried makig an aciton yet. Should not be too difficult since you want to to use the same image , you can copy once, and use paste during the action.
Make sure when you run the action as a batch, that you choose your destination. As a folder is safest, so you do not write over your original file.

How to overlay color image over a grayscale image without IMAQ?

I would like to display a color image over a grayscale image; I would like the color image look translucent. How would I do this without using IMAQ functions? I am currently displaying my grayscale image using Intensity Graph.

Transparency and overlays are really just arithmetic on the images. It
is either done by the windowing system or by you. At the moment you
can't set transparency on LV controls. You can set it on LV floating
windows on some OSes, but then you will need to have the windows lined up.
A more direct approach is to lighten or darken the color image elements
based upon whether they will display over white, black, or a shade of
gray. If the images don't have the same size pixels, this will have a
first step of resampling th
e images so they do. Then combine the pixels
using the transparency you were going to apply to the color and the
shade of gray beneath it. I'm being vague here because there are lots
of physical models for combining colors.
If I look in my paint program I see about fifteen, so this is where you
get to make a choice and decide if black behind a red pixel is black, or
dark red. It all depends on whether these are two transparent
images(acetate sheets) backlit, or is it a transparency over a
nontransmitting media like paper. Anyway, if you can be more specific
about what you want, none of this is hard, typically just scaling the
int32s, adding, and some sort of normalization.

Overlaying Photo image on multi-colour background

Hello,
I hope someone can point me in the right direction with this
one - as I'm a bit stuck.
I am creating a graphic for use as a background image on a
webpage that uses three colours. I want to add a picture in the top
right of the page. I have removed the background from this picture
using the magic want tool - but when I import it into my existing
graphic, it appears within a box with a white background. You can
see what I mean at this url:
http://www.magicalwonders.com/background/test.html
I'm not sure how to overlay this picture so that the graphic
underneath is showing? Is there an easy way to do this?
Hope someone can advise,
Many thanks,
Myles

other graphic.
Just for future reference, you can have multiple images in a
Fireworks document, too. You could have done that operation in
Fireworks. I thought you were trying to use the colorful image as a
Web page background and put Web content over it. I'm sorry I
misunderstood you.
Glad you found a way to work it, though!

Batch overlay multiple images

I'm an architect and would like to automate a process we do all the time: shadow studies. Here's a typical scenario: we render a view of a building, same camera angle, just changing the time of day for each rendering. Then we take those renderings and overlay them in Photoshop setting each layer to "Multiply", add a Brightness/Contast or Levels adjustment layer, and save said image. We do this for three times a year (one equinox and each solstice), often a few views of the building for each. So a typical shadow study might be 4-5 views, three times a years, so that's 12-15 composite images. This process gets repeated multiple times for each project as we change the design, so there is a lot of repetition.
I know how to create simple Actions. I know how to run a batch. What I don't know how to do and would like is a way to run a batch where I select some files and it creates the composite. The hurdle is making the Action and Batch be "generic" so that when I run the batch, I can select the images I want and the place to save it. That's the part I don't know how to do.
The Action I created is limited by (a) files open and (b) therefore only applicable to a certain number of open files (if I create the Action with 4 open files, it will only work on 4 files, not 3, not 5).
If required, I could probably script something. I know some programming/scripting, but have never done it for Photoshop.
I'm looking for guidance and a plan of attack. Any help would be greatly appreciated.

For free you may want to look at a tool that I think would be more suited for what you want to do. You could even put the build on Google Earth
Shadow and X-ray views no problem

Web Content Overlay | Local images do not load

Hi there,
the tutorial for the Web Content Overlay says, that you have to place all images and scripts in the same file folder, as the html-file itself, when you are using a local html-page.
example:
index.html
pic1.png
pic2.jpg
Unfortunatlly it isn`t working. Why? Any ideas? The pictures are not visible on my device or the folie preview builder.
And yes, if I open the html in my browser (like firefox or chrome) it works well.
It works only with pictures, which are hosted online on a server.
Thanks for answering.
Bart

It finally works!
I tried a lot, but now I know the misstake/failure/bug.
Unfortunatlly Indesign uses a absolute Link to the local Webpage.
example: C:/Jobs/Customers/CustomerFake/JobNo/v1/index.html
If this URL is too long (more than 40 characters), it does not work.
At first I thought, that my path was wrong, because I used german characters like ä or ß. But this doesn't matter. Its all about the lenght of the URL.

JEditorPane.setPage - detecting that asynchronous image loading is complete

Hi,
I'm using a JEditorPane to load and display an html page of a url by using
setPage(String url) ... and I've added a progress bar to show the user that loading is still occuring.
Currently i'm detecting that the page has finished loaded by listening for the property change event named "page", like this:
    this.viewEditorPane.addPropertyChangeListener(
      new PropertyChangeListener() {
        public void propertyChange(PropertyChangeEvent event) {
          if (event.getPropertyName().equals("page")) {
            loadingProgressBar.setIndeterminate(false);
            System.out.println("... finished loading");
      });I appreciate that images are loaded asynchronously.
So what I'm wondering is how I can detect that all these associated images have also completed loading?
Thanks ... Dougall

if you want to load images synchronously you can use like, (i got it from this forum only)
public class SynchronousHTMLEditorKit extends HTMLEditorKit {
    public SynchronousHTMLEditorKit() {
    public ViewFactory getViewFactory() {
        return new SynchronousImageViewFactory(super.getViewFactory());
    static class SynchronousImageViewFactory implements ViewFactory {
        ViewFactory impl;
        SynchronousImageViewFactory(ViewFactory impl) {
            this.impl = impl;
        public View create(Element elem) {
            View v = impl.create(elem);
            if((v != null) && (v instanceof ImageView)) {
                ((ImageView)v).setLoadsSynchronously(true);
            return v;
}

Setting order of precedence of ROI and Overlay in image

Hi Folks -
I am trying to have an overlay of points appear OVER a line ROI. I can convert the line ROI to an overlay, and clear the ROI, to get the effect I want.
However, the downside of that approach is that if the user wants to draw a new line, they always have to re-click on the line tool and redraw the line from scratch. If the ROI line is still in the image, the user can just mouse grab the end points or entire line and shift as needed. But if I leave the ROI line in the image, or clear it and then re-draw it, it always appears over the overlay.
The order makes a significant difference when not zoomed in on the image. One can hardly see the blue line if zoomed out.
I thought many years ago in the Vision user manual that I read about the order of precedence in an image for image, overlay, and ROI, and that ROI will always appear over the image and overlay. I don't see anything about this in the current Vision concepts manual.

Hello,
yes, it does seem that the ROI has precedence over overlay display. You could make the ROI dissapear when the mouse cursor leaves the image bounds and use your first solution (to convert the ROI to overlay). When the mouse cursor enters the image bounds, clear the overlays and add the original ROI back.
See the example in the attachment.
Best regards,
K
