DM642 Video Stabilization

Started by darko79 June 3, 2005
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 This message was sent using the Comp.DSP web interface on www.DSPRelated.com
