Method and apparatus for region-based moving image encoding and decoding |
摘要 |
In partitioning and encoding an image into multiple regions, the degree of freedom of the region shape has generally been low and setting regions based on image features was difficult. A moving image encoding apparatus includes a region partitioning section, an encoder, and a memory for motion-compensated prediction. The region partitioning section includes a partitioning processing section and a integration processing section. The partitioning processing section partitions the input image based on a criterion relating to the state of partition. The integration processing section integrates mutually close regions based on a criterion relating to the state of integration. Thereafter, each region is encoded. A large variety of region shapes can be produced by the integration processing section.</PTEXT>
