Abstract

The invention discloses a webp image coding method. Device and electronic equipment, The method comprises the following steps of: obtaining image data in a Webp format, and segmenting the image data to obtain a Y component, a U component and a V component, carrying out parallel coding processing on the Y component, the U component and the V component through an FPGA to obtain a coding Y component,a coding U component and a coding V component, and obtaining image coding data according to the coding Y component, the coding U component and the coding V component. The Y component, the U componentand the V component are respectively processed by adopting a parallel mode through the FPGA, so that the coding effect is good, and the real-time performance of coding the webp format image is improved. The technical problems that in the prior art, the encoding speed of the image in the webp format is low, and the real-time performance and bandwidth requirements are difficult to meet are solved,and the technical effects that the encoding effect is good, and the real-time performance of encoding the image in the webp format is improved are achieved.

Description

technical field [0001] The invention relates to the technical field of image coding, in particular to a webp image coding method, device and electronic equipment. Background technique [0002] Webp is a new generation image format launched by Google. Compared with the traditional jpeg image format, in the case of the same quality, the image in webp format occupies an average of 30% to 40% less memory than the jpeg format. Therefore, using images in webp format on the network can greatly reduce transmission bandwidth. However, compared with the encoding of images in jpeg format, the encoding of images in webp format is more complicated, and the computational complexity of images in webp format is more than 10 times that of images in jpeg format. However, the encoding speed of images in webp format by traditional CPU servers is slow, and it is difficult to meet real-time and bandwidth requirements. Therefore, it is an urgent problem to be solved to accelerate the encoding of...
