Effect of CNN shape segmentation on MPEG-4 shape bit-rate
Lauri Koskinen, A. Paasio, Mika Laiho, Kari A. I. Halonen · 2003
The effect of the cellular nonlinear network (CNN) shape segmentation algorithm on the shape bit-rate of a context-based arithmetic encoder has been simulated. Also, the correlation of shape boundary block and opaque block motion vectors and shape motion vectors and texture motion vectors has been simulated. It is found that, along with content-based MPEG-4 encoding, the intermediate results of the CNN algorithm can be used for power consumption reduction in the encoder.
