Samsung patents image decoding method that picks math tools based on picture details
Samsung describes a way to decode video images by looking at the direction of patterns in a small section of the picture. It uses that direction to choose the best mathematical tool for reconstructing the image data, which helps reduce errors when viewing the video.
In the filing’s own words
An image decoding method, an image decoding device, an image encoding method and an image encoding device are provided. The image decoding method includes: obtaining a reference block in a reference image; determining an intra mode for the reference block based on at least one of a plurality of neighboring samples of the reference block or a plurality of internal samples of the reference block; determining a transform kernel of the current block from among one or more transform kernels by using the intra mode for the reference block; and performing an inverse transform on the current block by using the transform kernel.
What exactly they claim (claim 1)
1. An image decoding method comprising: obtaining a reference block in a reference image; determining an intra mode for the reference block based on at least one of a plurality of neighboring samples of the reference block or a plurality of internal samples of the reference block; determining a transform kernel of a current block from among one or more transform kernels by using the intra mode for the reference block; and performing inverse transformation on the current block by using the transform kernel.
