Abstract

The invention discloses a picture processing method, which comprises the following steps of acquiring an original image, and carrying out virtual rotation on the original image in order to obtain a rotating image, wherein the rotating image comprises a plurality of macro blocks with no data dependence each other; sequentially acquiring Y channel data and UV channel data of each macro block, and carrying out macro block compression operation on the Y channel data and the UV channel data in order to obtain a compressed macro block; and acquiring a WebP picture according to boundary data of eachcompressed macro block. According to the picture processing method disclosed by the invention, the data dependence between the macro blocks of a WebP algorithm is removed by realizing virtual rotationof the image, and parallel data processing between the macro blocks of a WebP lossy compression algorithm is achieved; and through parallel processing of the Y channel data and the UV channel data, the efficiency of the WebP lossy compression is further improved. The invention further discloses a picture processing system, picture processing equipment and a computer readable storage medium, and the technical effects are also realized.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to an image processing method and system, an image processing device, and a computer-readable storage medium. Background technique [0002] The WebP image format is a new image compression format proposed by Google in 2010. Due to its high compression rate, it has been used by major Internet companies at home and abroad. However, in order to improve the compression rate, the WebP algorithm has designed a relatively complex image encoding and decoding principle, which makes its image encoding and decoding time several times that of the existing image format. Therefore, the research on the acceleration method of WebP algorithm is very important. [0003] OpenCL (full name in English: Open Computing Language, full name in Chinese: Open Computing Language) is a high-level programming language specially designed for parallel computing of heterogeneous computing...
