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.
