Hi, I'm new and just developing on J2EE. I am modifying an existing application (an OpenSource project). I need to save an image on a client sent by the server, but I do not know how.

Hi, I'm wondering what type of threshold would work well for distinguishing features that are very small (small in the xy sense) in comparison with the full spread, if that makes sense. The graythresh() function in Matlab that uses the Otsu method doesn't work too well for my data. Otsu is a clustering method where I think the # of pixel...
I am working on a bit of javascript to plot data on a <canvas>. The data points are marked by one of several different (small) image files. I am attempting to have the plot method wait until all the images are loaded. My best attempt thus far is such: var icon = { left : { air : new Image(), bone : new Image(), ...

Hey all, I am streaming some data down from a webcam. When I get all of the bytes for a full image (in a string called byteString) I want to display the image using OpenCV. Done fast enough, this will "stream" video from the webcam to an OpenCV window. Here's what I've done to set up the window: cvNamedWindow('name of window', CV_WIND...

It's working fine on all versions of IE/Firefox/Safari, with ONE exception... one machine that I tried it on tonight shows a white area where the transparent crop area should be displayed. Strangely enough, we've tried this on other machines running the same (most recent) version of IE 8...

I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I ...

I would like to use the images through xaml in a WPF application, but the only way I can figure is to do it through the code behind manually. Is there a way to do the winform to wpf image converti...

So basically what I'm ask...

I have a MemoryStream containing the bytes of a PNG-encoded image, and want to check if there is an exact duplicate of that image data in a directory on disk. The first obvious step is to only look for files that match the exact length, but after this I'd like to know what's the most efficient way to compare the memory against the files....
