Samsung patents AI method to fix blurry pixels in video decoding
Samsung describes a method for improving video quality during decoding by using a neural network to analyze the image data. The system identifies specific pixels that need adjustment and applies a correction value to sharpen or clarify them.
In the filing’s own words
Provided are an image decoding method and apparatus and an image encoding method and apparatus, which are for: acquiring a feature map for a plurality of pixels by inputting, into a neural network, a decoded image, a prediction image and coding context information for the current image including the plurality of pixels, mapping, on the basis of the feature map, an index corresponding to at least one pixel correction value for at least one pixel from among the plurality of pixels, identifying, on the basis of the index, a pixel correction value from the at least one pixel correction value, obtaining a corrected pixel value for the at least one pixel on the basis of the identified pixel correction value, and obtaining, on the basis of the current image, an output image corrected so that the at least one pixel has the corrected pixel value.
What exactly they claim (claim 1)
1. An image decoding method comprising: obtaining a feature map for a plurality of pixels by inputting, to a neural network, a decoded image, a prediction image, and coding context information for a current image comprising the plurality of pixels; mapping, based on the feature map, an index corresponding to at least one pixel correction value for at least one pixel from among the plurality of pixels; identifying, based on the index, a pixel correction value from the at least one pixel correction value; obtaining a corrected pixel value for the at least one pixel based on the pixel correction value; and obtaining, based on the current image, an output image in which the at least one pixel is corrected to the corrected pixel value.
