Backward ME with Linear Interpolation (backward)
- estimate m.v. backwards
- compensate for motion assuming velocity is constant
- do linear interpolation of the luminance component
Bi-Directional ME with Linear Interpolation (bidirectional)
- estimate m.v. both ways
- assume velocity is contant
- for each macroblock in the interpolated frame determine blocks that intersect with it, and keep m.v. from one with the biggest intersection area
- do linear interpolation of the luminance component
Bi-Directional ME with pixel 4-class classifier (pixel classifier)
- same as previous, but instead of linear interpolation use 4-class classifier
