Samsung patents method to adjust image compression using neural networks

This patent describes a way to decode compressed images by using a neural network to determine how to unpack the data. It adjusts the statistical rules used to read the file based on specific details found in the image itself, rather than using a fixed set of rules.

Why it mattersIt offers a more precise way to handle image compression, which could lead to better quality videos or photos at the same file size.

In the filing’s own words

An image decoding method includes obtaining, second feature data from a bitstream for first feature data of a current image, obtaining quantization data and probability data by applying the second feature data to a neural network, modifying the probability data, based on sample values of the quantization data, obtaining quantized first feature data by applying entropy decoding, based on the modified probability data, on bits included in the bitstream, obtaining dequantized first feature data by dequantizing the quantized first feature data based on the sample values of the quantization data, and reconstructing the current image by performing neural network-based decoding on the dequantized first feature data. The first feature data having been obtained by performing neural network-based encoding on the current image.

What exactly they claim (claim 1)

1. An image decoding method, comprising: obtaining second feature data from a bitstream for first feature data, the first feature data having been obtained by performing neural network-based encoding on a current image; obtaining quantization data and probability data by applying the second feature data to a neural network; modifying the probability data, based on sample values of the quantization data; obtaining quantized first feature data by applying entropy decoding, based on the modified probability data, on bits comprised in the bitstream; obtaining dequantized first feature data by dequantizing the quantized first feature data based on the sample values of the quantization data; and reconstructing the current image by performing neural network-based decoding on the dequantized first feature data.
