IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18673266 titled 'IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS
The patent application describes methods and apparatuses for decoding images using a recursive division structure.
- The method involves receiving a bitstream obtained by encoding the image, dividing a first coding block into multiple second coding blocks, generating a prediction block based on syntax information from the bitstream, and reconstructing the second coding block using the prediction block and a residual block obtained through dequantization and inverse-transform.
- The first coding block is divided based on quad tree, binary tree, or triple tree division.
- The innovation allows for efficient decoding of images by recursively dividing coding blocks and generating prediction blocks based on syntax information from the bitstream.
Potential Applications:
- Image and video compression technologies
- Multimedia communication systems
- Digital signal processing applications
Problems Solved:
- Efficient decoding of images
- Improved compression and transmission of multimedia data
Benefits:
- Enhanced image quality

Questions about the technology: 1. How does the recursive division structure improve image decoding efficiency?
- The recursive division structure allows for more accurate prediction block generation, leading to better image reconstruction.
2. What are the potential drawbacks of using quad tree, binary tree, or triple tree division in image decoding?
- These division methods may introduce complexity in the decoding process, potentially impacting computational efficiency.
Original Abstract Submitted
Disclosed are methods and apparatuses for decoding an image. A method includes receiving a bitstream obtained by encoding the image; dividing a first coding block into a plurality of second coding blocks; generating a prediction block of a second coding block based on syntax information obtained from the bitstream; and reconstructing the second coding block based on the prediction block and a residual block of the second coding block, the residual block being obtained by performing a dequantization and an inverse-transform on quantized transform coefficients from the bitstream. The first coding block has a recursive division structure. The first coding block is divided based on at least one of a quad tree division, a binary tree division or a triple tree division.
