Samsung patents video decoding method using directional intra prediction
Samsung describes a method for decoding video images by predicting pixel values in a block based on surrounding pixels. The system tests different directional patterns to find the best match for reconstructing the image data.
In the filing’s own words
An image decoding method includes: identifying a first sample set and a second sample set reconstructed before the current block; performing intra prediction by using one of the first sample set or the second sample set as a reference sample set according to each directional mode of a plurality of directional modes to obtain a plurality of prediction sample sets corresponding to the other one of the first sample set or the second sample set; determining a directional mode for the current block, from among the plurality of directional modes, based on cost values corresponding to comparison results between each prediction sample set of the plurality of prediction sample sets and the other one of the first sample set or the second sample set; and reconstructing the current block by performing intra prediction on the current block according to the directional mode for the current block.
What exactly they claim (claim 1)
1. An image decoding method comprising: identifying a first sample set reconstructed before a current block and a second sample set reconstructed before the current block; performing intra prediction by using one of the first sample set and the second sample set as a reference sample set according to each directional mode of a plurality of directional modes to obtain a plurality of prediction sample sets corresponding to the other one of the first sample set and the second sample set; determining a directional mode for the current block, from among the plurality of directional modes, based on cost values corresponding to comparison results between each prediction sample set of the plurality of prediction sample sets and the other one of the first sample set and the second sample set; and reconstructing the current block by performing intra prediction on the current block according to the directional mode for the current block.
