IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18673242 titled 'IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS
The patent application describes methods and apparatuses for decoding an image using a recursive division structure.
- The method involves receiving a bitstream, dividing a coding block into smaller blocks, generating a prediction block based on syntax information, and reconstructing the block using the prediction block and a residual block.
- The first coding block is divided based on quad tree, binary tree, or triple tree division.
- The residual block is obtained through dequantization and inverse-transform of quantized transform coefficients from the bitstream.
Potential Applications:
- Image and video compression technologies
- Multimedia communication systems
- Digital signal processing applications
Problems Solved:
- Efficient image decoding
- Improved image quality
- Reduced data transmission bandwidth
Benefits:
- Higher compression ratios
- Enhanced image quality
- Reduced storage and transmission costs
Commercial Applications:
- Video streaming services
- Digital media platforms
- Telecommunication companies
Questions about Image Decoding: 1. How does the recursive division structure improve image decoding efficiency?
- The recursive division structure allows for more accurate prediction and reconstruction of image blocks, leading to higher compression ratios and improved image quality.
2. What are the potential drawbacks of using quad tree, binary tree, or triple tree division in image decoding?
- While these division methods offer flexibility in block partitioning, they may introduce complexity in the decoding process and require additional computational resources.
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.
