Title:
CLOUD DESKTOP IMAGE PROCESSING METHOD, IMAGE PROCESSING METHOD, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/094077
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a cloud desktop image processing method, an image processing method, a device, and a storage medium. In the present application, the cloud desktop image processing method comprises: segmenting a cloud desktop image into a plurality of image blocks, and, according to color values of pixels of the image blocks, performing content classification on the image blocks; performing lossless compression on image blocks of the target type to ensure the display quality of the image blocks of the target type; and, according to the smoothness of image blocks of the non-target type, using quality parameters adapted for the smoothness to perform lossy compression on the image blocks of the non-target type, so as to reduce the size of compressed data on the basis of ensuring the display quality of the image blocks. Therefore, the present application uses different image compression modes for processing image blocks of different content types, so as to make compression rates of different areas to be matched with the content of the respective areas, thus considering both the picture display quality and the size of compressed data of different areas of images, and further considering both the picture display quality and the network transmission bandwidth of cloud desktops.
