Abstract
Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature-based video compression to improve the accuracy and versatility of encoding interframe motion and intraframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrary configurations.
