SIGNALING DECODING USING SEGMENTATION INFORMATION

The invention also relates to a method and an apparatus for decoding data (for still image or video processing) from a code stream. And obtaining two or more than two segmentation information element sets from the code stream. Then, each split information element set of the two or more split information element sets is respectively input into two or more split information processing layers of a plurality of cascade layers. In each of the two or more divided information processing layers, the respective divided information set is processed. And acquiring decoded data for image or video processing according to the segmentation information processed by the plurality of cascade layers. Thus, the data may be decoded from the code stream in a hierarchical structure in an efficient manner. 本发明还涉及用于从码流中解码(用于静止图像或视频处理的)数据的方法和装置。从所述码流中获取两个或两个以上分割信息元素集。然后，将所述两个或两个以上分割信息元素集中的每个分割信息元素集分别输入到多个级联层中的两个或两个以上分割信息处理层中。在所述两个或两个以上分割信息处理层中的每个分割信息处理层中，处理各自的分割信息集。根据所述多个级联层处理的所述分割信息，获取用于图像或视频处理的经解码数据。因此，可以在分层结构中以高效的方式从所述码流中解码所述数据。
