Motion Vector calculation

How to find the motion vector of a macroblock?

[Walter Roberson]

That sounds like an image processing algorithm question, rather than a MATLAB question.

I am doing a project in image processing, in which i have to group the similar images in a video. Motion based object detection concept is also used in that. For that, i need to calculate motion vectors.(Block Matching motion estimation). can anyone help me with the code snippet for the calculation of motion vectors.

Note: The input video is seperated into individual images and each image is divided into 8*8 blocks. I need to calculate motion vectors for each block..
