Motion estimation for compression of calibrated multi-view image sequences
First Claim
1. A method for estimating motion of each of a plurality of tessels in an intermediate image relative to a reference image, the method comprising:
- searching the reference image to find points that lie along epipolar lines in the reference image corresponding to upper-left and lower-right vertices of the tessel, respectively, that result in a best-matching shape;
estimating a depth of each of at least two of the vertices of the tessel; and
using the depth estimates of the at least two vertices of the tessel to estimate the motion of the tessel relative to the best-matching shape.
