Interframe image coding with three-dimensional gradient motion estimation
Two new methods for coding image sequences in video conferencing systems are developed in this dissertation. A simple 3-D gradient operator is developed to estimate motion in an image sequence on a pixel-by-pixel basis. A stochastic 3-D gradient operator is also developed for a gradient calculation...
