I have a bitmap sourceImage.bmp locking it's bits: BitmapData dataOriginal = sourceImage.LockBits(new Rectangle(0, 0, sourceImage.Width, sourceImage.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb); Do analysis, get a clone : Bitmap originalClone = AForge.Imaging.Image.Clone(dataOriginal); unlocking bits: sourceImage.UnlockBits(dataOriginal); is it possible to specify which part of "dataOriginal" to copy (x,y,w,h)? or to create new data from the dataOriginal, specifying X and Y coordinates as well as H and W? The aim is to copy a small area from this image. This method might be

I'm trying to develop an image focusing algorithm for some test automation work. I've chosen to use AForge.net, since it seems like a nice mature .net friendly system. Unfortunately, I can't seem to find information on building autofocus algorithms from scratch, so I've given it my best try: take image. apply sobel edge detection filter, which generates a greyscale edge outline. generate a histogram and save the standard dev. move camera one step closer to subject and take another picture. if the standard dev is smaller than previous one, we're getting more in focus. otherwise, we've past the

Like many people already seem to have (there are several threads on this subject here) I am looking for ways to create video from a sequence of images. I want to implement my functionality in C#! Here is what I wan't to do: /*Pseudo code*/ void CreateVideo(List<Image> imageSequence, long durationOfEachImageMs, string outputVideoFileName, string outputFormat) { // Info: imageSequence.Count will be > 30 000 images // Info: durationOfEachImageMs will be < 300 ms if (outputFormat = "mpeg") { } else if (outputFormat = "avi") { } else { } //Save video file do disk } I know there's a project called
