Abstract

Interframe video coders using the discrete cosine transform (DCT) and motion compensation (MC) produce block artifacts in the decoded video at low bit-rates. Results on lapped orthogonal transforms (LOTs) suggest that they can reduce these artifacts. However, LOTs are difficult to use efficiently with motion compensation because of block overlap. The authors propose a new video coding algorithm that forms a natural connection between LOTs and motion compensation using two novel concepts: overlapped motion compensation (OMC) and overlapped macroblocks using frequency domain coefficients.
