METHOD AND DEVICE FOR ENCODING/DECODING IMAGES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18160981 titled 'METHOD AND DEVICE FOR ENCODING/DECODING IMAGES

Simplified Explanation

The patent application describes a method and device for encoding/decoding images based on the scan type of a residual signal for a current block.

• The method involves determining the scan type of the residual signal for a block based on whether it is a transform skip block.
• The scan type is then applied to the residual signal for the block, with transform skip blocks being those where transform is not applied.

Key Features and Innovation

• Method for encoding images based on scan type of residual signal.
• Differentiates between transform skip blocks and applies scan type accordingly.

Potential Applications

This technology can be applied in image and video compression algorithms to improve encoding efficiency.

Problems Solved

Questions about Image Encoding

How does the scan type of a residual signal impact image encoding efficiency?

The scan type determines how the residual signal is processed, affecting the compression ratio and image quality.

What are the potential drawbacks of using transform skip blocks in image encoding?

Transform skip blocks may result in lower compression efficiency but can be beneficial for preserving image details.

Original Abstract Submitted

A method and a device for encoding/decoding images are disclosed. The method for encoding images comprises the steps of: deriving a scan type of a residual signal for a current block according to whether or not the current block is a transform skip block; and applying the scan type to the residual signal for the current block, wherein the transform skip block is a block to which transform for the current block is not applied and is specified on the basis of information indicating whether or not transform for the current block is to be applied.
