METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18519996 titled 'METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL
Simplified Explanation
The abstract describes a method and apparatus for processing a video signal, specifically focusing on decoding an image signal. The method involves determining a modified intra prediction mode based on the ratio between the width and height of a current block, selecting an inverse non-separable transform set based on the modified intra prediction mode, and applying an inverse non-separable transform matrix to the top-left region of the current block.
- Ratio between width and height used to determine modified intra prediction mode
- Selection of inverse non-separable transform set based on modified intra prediction mode

Benefits
The method and apparatus described in the patent application can enhance the quality of decoded video signals, reduce artifacts, and optimize the processing of non-uniform blocks.
Potential Commercial Applications
The technology could be utilized in video streaming services, video conferencing platforms, surveillance systems, and digital media players.
Possible Prior Art
One possible prior art could be the use of traditional intra prediction modes and transform matrices in video processing algorithms.
What are the specific types of video signals that can benefit from this technology?
This technology can benefit video signals with non-uniform block sizes, where traditional decoding methods may not be as effective. By adapting the prediction mode and transform set based on the block dimensions, the decoding process can be optimized for various types of video signals.
How does this technology compare to existing methods in terms of computational efficiency?
This technology aims to improve the efficiency of decoding image signals by adapting the prediction mode and transform set based on the block dimensions. By optimizing these parameters, the decoding process can be more accurate and efficient compared to traditional methods that do not take block size variations into account.
