DM642 Video Stabilization

I would like to make implementation of video stabilization algorithm on
DM642. Can I process that. I will implement SAD or bit-plane algorithm. Do
I need external memory. Video is in standard PAL resolution.

Hi,
I have implemented a few image stabilization algorithms on the DM642.
You do need external memory for several reasons:
1. Assuming you are selecting random blocks in other find the global
motion vector, you will need access to the entire image
2. The DM642 can't hold internally a PAL image( 720x576)
3. After finding the global motion vector, you will need to crop from the
entire image a portion, You will need access to the entire image
4. Assuming you are using TI's DDK, they require at least three buffers.

So I guess external memory is a must
