Samsung patents image compression using two types of neural networks

Samsung describes a method for compressing images by converting them into a simplified data format using a reversible neural network. It then uses a second, irreversible network to help predict the best way to pack that data efficiently for storage or transmission.

Why it mattersThis filing focuses on improving how digital images are compressed, which could lead to smaller file sizes or better quality in future software updates.

In the filing’s own words

There is provide an image encoding method including transforming an image block into a first latent representation based on an invertible neural network, transforming the first latent representation into a second latent representation based on a non-invertible neural network, estimating a probability distribution of the first latent representation, and performing entropy encoding on the first latent representation based on the probability distribution by using an entropy encoder.

What exactly they claim (claim 1)

1. An image encoding method comprising: transforming an image block into a first latent representation based on an invertible neural network; transforming the first latent representation into a second latent representation based on a non-invertible neural network; estimating a first probability distribution of the first latent representation based on the second latent representation; and performing entropy encoding on the first latent representation based on the first probability distribution by using a first entropy encoder.
