METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18520383 titled 'METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL
Simplified Explanation
The abstract describes a method and device for processing a video signal, specifically decoding an image signal using non-separable transform sets and transform kernels.
- Non-separable transform sets are determined based on an intra-prediction mode of the current block.
- A transform kernel is selected from the non-separable transform set for the current block.
- The selected transform matrix is applied to the upper left region of the current block.
Potential Applications
This technology can be applied in video encoding and decoding systems, image processing applications, and multimedia communication devices.
Problems Solved
1. Efficient processing of video signals. 2. Improved image quality through non-separable transform sets.
Benefits
1. Enhanced video compression capabilities. 2. Increased accuracy in image signal decoding. 3. Optimal utilization of transform kernels for better image representation.
Potential Commercial Applications
Optimized video streaming services, advanced video editing software, high-definition television broadcasting systems.
Possible Prior Art
One possible prior art could be the use of separable transform sets in video signal processing, which may not provide the same level of efficiency and image quality as non-separable transform sets.

Original Abstract Submitted
Embodiments of the present disclosure provide a method and device for processing a video signal. A method for decoding an image signal according to an embodiment of the present disclosure comprises the steps of: determining a non-separable transform set index indicating a non-separable transform set used for a non-separable transform of a current block from among non-separable transform sets predefined on the basis of an intra-prediction mode of the current block; determining. as a non-separable transform matrix, a transform kernel indicated by a non-separable transform index for the current block from among transform kernels included in the non-separable transform set indicated by the non-separable transform set index; and applying the non-separable transform matrix to an upper left region which of the current block, which is determined according to the width and height of the current block, wherein each of the predefined non-separable transform sets includes two transform kernels.
