Abstract
There are provided an improved scan interleaving method based on context values of neighboring pixels, an improved binary shape encoding/decoding method, and encoding/decoding apparatus suitable for the same. The hierarchical binary shape encoding apparatus includes a portion for down-sampling for SI method, the portion for performing down-sampling for SI method on the binary shape data to form a base layer, a portion for encoding the base layer supplied from the down-sampling portion, and a portion for encoding an enhancement layer having the current binary shape data by referring to the base layer or a preceding frame. The encoding apparatus can perform hierarchical encoding, thereby enhancing the overall coding efficiency.
