发明名称 Image compression method using a table of hash values corresponding to motion vectors
摘要 A method of compressing image data comprising the steps of generating a set of motion vectors representative of one or more image frames, generating, by means of a predetermined hash function a set of hash values, responding to said motion vectors, and storing as a code book said hash values in the form of a table or array. Vector quantisation may be used to index the hash values in the table or array to enable them to be retrieved by a decoder.
