Video decoding and encoding methods, data transmission methods for images and storage media readable by non-routine computers.

Abstract

The invention relates to a method for decoding images performed by a decoding device comprising the following steps: inferring predictive patterns by performing a prediction for the current block; determining whether the current block is partitioned based on the size of the current block and the largest transformation size; partitioning the current block into transformed blocks based on whether the current block is partitioned; inferring transformation coefficients for the transformed blocks; inferring residual patterns by performing an inverse transformation process for the transformation coefficients; and generating a reconstructed image based on the residual patterns and predictive patterns, where the size of the current block is greater than the largest transformation size, it is determined that the current block is partitioned. The invention also relates to a method by which a digital image and storage medium can be read by a non-transferable computer.
