I have a video of an eye, converted into pngs.
I need to annotate the pupil, with an ellipse. Sometimes the eye does not move, and I would like to annotate the next image with the ellipse/pupil found in the previous image.
How would I do this?
I tried:
importing json, but this is a bit tedious and its creates a new image/ID.
Create copy of current annotation but the new annotation stays on the same image and can't be pasted in the next similar image.
Thank you very much for your help.

I haven't dabbled with animated gifs for a very long time. I'd like to create something similar to this:
https://dribbble.com/shots/2941889-Wind
I can't imageine whoever created this animated frame-by-frame to get that result. So i'd like to know what tools there are for doing something like that? Or perhaps i'm all wrong and the only way to do it is frame-by-frame?
Just some advice where to get started if anyone is able.
So what i did in the end was use Adobe Illustrator to create the paths.
I then changed the stroke to dashed. Modifying the dash i was able to make it appear as thought the line was growing along the path. I then created more paths.
I then created a js file to incrementally increase the dash and save a gif. This created me over 100 snapshots.
Imported these into Adobe Photoshop and export! Bingo!
Im trying to check if a screenshot contains an image that is saved in the project resources, I need to find a 100% match only and would like to not use any extra libraries, now with that being said, I have no idea how to do so.
heres a few questions:,
do I compare the two buffered images together? do I change them into something else?
Il have to compare it atleast once a second or so. (just as general information)
I have a resource folder under my project in eclipse and the .png files are shown as text, is there a way to change that? I tried tinkering with the settings, no luck yet.
public static BufferedImage screenshot(){
BufferedImage capture = robot.createScreenCapture(screenSize);
return capture;
}
this is my screenshot, another bufferedimage is for example "compare", where the size of the compared image is smaller than the screenshot. how will I be able to check if the image contain the second image?
*For those who wondering, im trying to make a simple program that clicks a certain image once it pops up.
I'd like to append a border (20px white) to an image, save as a new jpeg image (orginal image with a border), I don't know how do I start. Can anyone give me a direction or code example?
Thanks
You have two ways to do it:
On your UI, wrap the image with a Border element with the correct settings and use new WriteableBitmap(borderElement, null) to create a new WriteableBitmap which you can then save using the SaveJpeg extension method.
Your other option is to use the WriteableBitmapEx class library to graphically add the graphical elements you want.
I've used both. The advantages for (1) is that there's less hassle in the sense of adding a dependeny on another DLL. The advantage in (2) is that you don't need to mess with your UI to create the image.
I am building an Eclipse RCP application, based on eclipse 3.5.
I'd like to modify an image at runtime. The image is loaded and will be used as an icon, but depending on the situation, I'd like to add a filter on the image to give it a red or orange color, depending on some user-configured value.
It's the image transformation that I'm interested in. I already know how to get the image and ask a component to display it.
Has anybody done that? Thanks for your help :)
There are possibly many choices for doing just that, you can use ImageIO to load an image as BufferedImage and then get the Graphics2D and modify it as you wish. When you are finished modifying you can reaasign the newly created image back into your component which holds the original image and thats it.
You can of course look for some libraries to allow you easier image manipulation, maybe jmagick or something similar.
You can use DecoratingLabelProvider with a suitable ILabelDecorator. See also FAQ What is a label decorator?
I have a set of really big images out of which I need to crop little snippets. These snippets are all exactly the same size but don't follow a strict pattern so I can't do this programatically.
Ideally I would like to open up one of the big files and be able to point and click on say, the top left corner of a snippet and have that automatically be saved to disk without even having to enter a file name, and then continue on with the rest. (Of course this would be the ideal way which I know is probably way off the real possible way!).
I started doing this in Photoshop CS4 but cropping a snippet, saving, undoing (to get to the full image), and starting over again takes way too long.
Maybe someone has a better way to do this in photoshop or in some other software.
Thanks for reading!
Instead of cropping and undoing, you could:
make (or resize) a selection
copy the selection to a new image
save the image
close the image
You might need to split it into two actions, I don't know enough about programming Photoshop.
Thank you everyone for your input.
I ended up doing this with a suggestion a colleague of mine came up with. It consisted of creating a Photoshop "slice" over the first region I wanted to crop and then cloning that region over the rest of the other sections. After that, using Save For Web (and ofter hitting Continue when PS complained about how that image was way beyond Save For Web's capabilities) I could save all images at once.
This was the fastest and easiest method I could find. Until then I was going with Mark Ransom's method.
