Definitions
- This invention relates to video processing and particularly to motion compensation of video processes.
- FIG. 3 is a diagram of apparatus according to another embodiment of the invention.
- phase correlation is a particularly useful technique, other and perhaps simpler forms of correlation could alternatively be employed, such as block matching.
- a gradient approach could also be employed.
