Title:
DATA PROCESSING METHOD AND APPARATUS FOR IMAGE COMPRESSION, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/130653
Kind Code:
A1
Abstract:
Provided are a data processing method and apparatus for image compression, a device, and a storage medium. The method comprises: segmenting an image to be compressed into a plurality of image matrices, and performing first matrix calculation on elements of the image matrices to obtain first intermediate matrices (S1); configuring a storage space size and storage addresses of the first intermediate matrices according to the resolution and pixel component depth of the image to be compressed, and storing the first intermediate matrices (S2); reading the first intermediate matrices, performing second matrix calculation on elements of the first intermediate matrices and elements of a preset conversion matrix to obtain second intermediate matrices, and performing third matrix calculation on elements of the second intermediate matrices and the elements of the conversion matrix to obtain third intermediate matrices (S3); and performing fourth matrix calculation on the conversion matrix and the third intermediate matrices to obtain result matrices, and encoding the result matrices to obtain a compressed image (S4).
