Abstract

According to one aspect, an image encoding device (100) is provided, which is used for dividing (800) an image data block into sub-blocks step by step; determining (802) that the encoded sub-block belongs to a block using unequal size division; according to Preparing (804) a phase for said sub-block of said block partitioned using unequal size using the size of the sub-block of the block partitioned using unequal size and the partition type of at least one adjacent block using the block partitioned using unequal size Neighboring block list; according to the prepared neighboring block list, deduce (806) a context model, the context model is used to encode the partition information of the sub-block of the block using unequal size partitioning into the bitstream .

Description

technical field [0001] The invention relates to the field of image processing, eg image and / or video encoding and / or decoding. Background technique [0002] Digital video communication and storage applications are implemented in many digital devices such as digital cameras, cellular radiotelephones, notebook computers, broadcasting systems, and video conferencing systems. Video compression is one of the most important and challenging tasks in these applications. Video compression is a complex task constrained by two conflicting parameters of compression efficiency and computational complexity. Video coding standards such as ITU-T H.264 / AVC (Advanced Video Coding) or ITU-T H.265 / HEVC (High Efficiency Video Coding) provide a good compromise between these parameters. [0003] When encoding video, the progressive encoder generates various syntax elements that further signal the bitstream according to the assigned probability model. The syntax elements contain data representin...
