SYSTEM FOR VERY LOW RATE FACE IMAGE COMPRESSION

摘要

In this system for very low rate face image compression, the compression is obtained by decomposition of a digital face image over a redundant library of functions. The image is converted into a series of geometric function indexes, along with their respective coefficient tuples which may be used to reconstruct the compressed face image for display. The system includes a face model encoder (10), a matching pursuit encoder (13) fed with residual face image signals (14) delivered from a first output of said face model encoder (10) and giving MP -parameter signals (15) to a first input of a bit-stream generator (16) which delivers the desired bit-stream (17). The face model encoder (10) has a second output giving model parameter signals (18) to a second input of said bit-stream generator (16).
