Optical Flow
显示 更早的评论
Thanks for the response David. I have optical flow in a matrix. What i want to do is actually calculate optical flow by block matching as the result is quite noisy. Also I only want to calculate the optical flow of the object not the whole frame. I am unable to do so as LK algorithm works on image not on co-ordinates.

You could try using local feature matches to find the optic flow. Then your problem is essentially segmentation - you need to find areas representing separate objects, either on the basis of properties of the images, or using the flow itself.
To find optic flow using local features, you could again look at the file exchange for examples, such as this. This particular example may not be the best one - you should search for something that works best for your application.
