METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18084127 titled 'METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL
Simplified Explanation
The present invention is a method and apparatus for processing a video signal. It involves decoding an image signal using a modified intra prediction mode and an inverse non-separable transform set. The method includes the following steps:
- Determining a modified intra prediction mode for a current block based on the ratio between its width and height and the intra prediction mode.
- Determining an inverse non-separable transform set based on the modified intra prediction mode.
- Applying an inverse non-separable transform matrix selected from the set to the top-left region of the current block, determined by its width and height.
Potential applications of this technology:
- Video encoding and decoding systems
- Video streaming services
- Video surveillance systems
- Video conferencing platforms
Problems solved by this technology:
- Efficient processing of video signals with blocks of different width and height
- Improved image quality and compression efficiency
- Reduced computational complexity in video decoding
Benefits of this technology:
- Enhanced video compression and transmission efficiency
- Improved video quality and resolution
- Reduced bandwidth and storage requirements
- Faster video decoding and processing
Original Abstract Submitted
Embodiments of the present invention provide a method and apparatus for processing a video signal. A method for decoding an image signal according to an embodiment of the present invention comprises the steps of: for a current block having a width and a height different from each other, determining a modified intra prediction mode from an intra prediction mode, on the basis of a ratio between the width and the height of the current block and the intra prediction mode; determining an inverse non-separable transform set on the basis of the modified intra prediction mode; and applying an inverse non-separable transform matrix selected from the inverse non-separable transform set with respect to the top-left region of the current block, which is determined according to the width and the height of the current block.
