MATLAB: Can anybody please give me the matlab code to estimate and compare the motion vectors of blocks of two images

Image Processing Toolboxmotion estimation

I did upto divide the images into blocks. After that how to find motion vector for each block and compare those values with the other frame blocks to find a best match?

Algorithms for motion estimation are a theory question, not a MATLAB implementation question.

One of the algorithms is mentioned at http://www.mathworks.co.uk/matlabcentral/answers/21713-cross-diamond-cds-block-matching-algorithm-for-motion-estimation

Yes.

swap1324 = @(x)([x((floor(size(x,1)/2)+1):end,(floor(size(x,2)/2)+1):end) x((floor(size(x,1)/2)+1):end,1:floor(size(x,2)/2)); x(1:floor(size(x,1)/2),(floor(size(x,1)/2)+1):end) x(1:floor(size(x,1)/2),1:floor(size(x,2)/2))]);
I = imread('cameraman.tif'); %sample image
I2 = swap1324(I);
imtool(I2)

Obviously the above should be broken down into it's own function that doesn't have to repeat the function floor(size(stuff))) over and over again.
