METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18389320 titled 'METHOD AND APPARATUS FOR PROCESSING IMAGE SIGNAL
Simplified Explanation
The abstract describes a method and apparatus for processing video signals, specifically focusing on determining input and output lengths for a non-separable transform based on the size of a current block, and applying a corresponding transform matrix to the block.
- The method involves determining the input and output lengths of a non-separable transform based on the height and width of the current block.
- A non-separable transform matrix is then selected based on the determined input and output lengths.
- The selected transform matrix is applied to the current block, with specific dimensions set when the block size is 4x4.
Potential Applications
This technology could be applied in video encoding and decoding systems, image processing applications, and multimedia communication devices.

The potential cost and resource savings from implementing this technology are not explicitly discussed in the article, leaving this question unanswered.
Original Abstract Submitted
Embodiments of the disclosure provide a method and apparatus for processing video signals. An image signal decoding method according to an embodiment of the disclosure comprises the steps of: determining, on the basis of the height and width of a current block, an input length and output length of a non-separable transform; determining a non-separable transform matrix corresponding to the input length and output length of the non-separable transform; and applying the non-separable transform matrix to the current block, wherein, when the height and width of the current block are 4 each, the input length and output length of the non-separable transform are determined to be 8 and 16 respectively.
