Will the motion estimation algorithm work? Is there any other way to determine the directional vectors?

What motion estimation algorithm are you referring to? There are many.
Personally I would recommend block by block phase correlation.

Yes! Break your reference and target images into blocks. Perform the phase correlation on each block (probably padded with zeros to a bigger block in the target image), recover the u,v, components of motion, store them in their own matrices.

Hey Sean...How can I plot motion field for Phase Correlation method ??? I want to plot motion field for both Phase Correlation and block by block phase correlation....

The Video and Image Processing Blockset provides optical flow functionality...written just for this purpose!
Cheers,

I am a student and Can I use the trial version of the Simulink Video and Image Processing Blockset ???Will it have all the features ???

Our student versions are fully functional. You can take full advantage of whichever of our products to which you have access.

to find the direction of my moving object,I have divided the video frame into blocks. how do i know in which block is my object present now.
