METHOD AND APPARATUS OF ENCODING/DECODING IMAGE DATA BASED ON TREE STRUCTURE-BASED BLOCK DIVISION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240031603 titled 'METHOD AND APPARATUS OF ENCODING/DECODING IMAGE DATA BASED ON TREE STRUCTURE-BASED BLOCK DIVISION

Simplified Explanation

The abstract describes a method and apparatus for encoding and decoding image data. The method of decoding an image involves receiving a bitstream containing the encoded image, obtaining index information to determine the block division type of the current block in the image, and determining the block division type from a pre-defined candidate group in the decoding apparatus. The candidate group includes various division types such as non-division, quad-division, binary-division, and triple-division. The current block is then divided into sub-blocks, and each sub-block is decoded using syntax information obtained from the bitstream.

  • The patent/application is related to image data encoding and decoding.
  • The method involves decoding an image by obtaining index information and determining the block division type.
  • The block division type is determined from a pre-defined candidate group in the decoding apparatus.
  • The candidate group includes various division types such as non-division, quad-division, binary-division, and triple-division.
  • The current block is divided into sub-blocks, and each sub-block is decoded using syntax information from the bitstream.

Potential Applications:

  • This technology can be used in various image and video compression applications.
  • It can be implemented in devices such as cameras, smartphones, and video streaming platforms.
  • It can improve the efficiency of image and video transmission over networks.

Problems Solved:

  • The technology solves the problem of efficiently encoding and decoding image data.
  • It addresses the issue of determining the block division type in image decoding.
  • It provides a solution for dividing blocks into sub-blocks for more efficient decoding.

Benefits:

  • The technology improves the compression efficiency of image and video data.
  • It reduces the bandwidth and storage requirements for transmitting and storing images and videos.
  • It allows for faster decoding and playback of compressed image and video data.


Original Abstract Submitted

disclosed are methods and apparatuses for image data encoding/decoding. a method of decoding an image includes receiving a bitstream in which the image is encoded; obtaining index information for specifying a block division type of a current block in the image; and determining the block division type of the current block from a candidate group pre-defined in the decoding apparatus. the candidate group includes a plurality of candidate division types, including at least one of a non-division, a first quad-division, a second quad-division, a binary-division or a triple-division. the method also includes dividing the current block into a plurality of sub-blocks; and decoding each of the sub-blocks with reference to syntax information obtained from the bitstream.
