After we classify the mesh frames in the animation model into intra- and inter-meshes, each mesh frame is decomposed into linear triangular strips, which in turn are partitioned into several fixed-length segments.

• I-frames contain an entire image. They are coded without reference to any other frame except (parts of) themselves. • May be generated by an encoder to create a random access point (to allow a decoder to start decoding properly from scratch at that picture location). • May also be generated when differentiating image details prohibit generation of effective P or B-frames. WebDec 13, 2016 · If the intra flag is false, each block will predict pixel values by copying pixels from 1 or 2 previously coded reference frames at specified pixel offsets, called motion vectors.
