Embodiment Construction

[0060] figure 1 It is a schematic diagram of a typical application scenario of the image compression method of the embodiment of the present invention. Such as figure 1 As shown, the server 11 takes a screenshot of the local desktop, applies the image compression method of the embodiment of the present invention to compress the local desktop image obtained by the screenshot, and obtains a corresponding compressed code stream. The server 11 transmits the compressed code stream to the remote client device through the communication network, for example including figure 1 PC 12, mobile terminal 13 and portable computer 14 in. After receiving the compressed code stream sent by the server 11, the PC 12, the mobile terminal 13 and the portable computer 14 decode the compressed code stream, recover and display the desktop image of the server 11. Next, from the perspective of server 11 performing local desktop image compression, the image compression method of the embodiment of the ...

Abstract

The invention provides an image compression method and equipment, and a system. The method comprises: according to a preset image block size, segmenting a to-be-compressed image into a plurality of image blocks that are not overlapped mutually; according to the colors and/or texture features of all image blocks, determining types of all the image blocks; and on the basis of a mapping relation between a preconfigured image type and a compression rule as well as the types of all the image blocks, carrying out compression coding on all image blocks so as to complete compression of the to-be-compressed image. According to the method, the equipment, and the system, effective compression of a mixed image containing text graph information and natural image information can be realized.

Description

technical field [0001] The invention relates to data processing technology, in particular to an image compression method, device and system, and belongs to the field of communication technology. Background technique [0002] With the continuous improvement of computer application technology and the rapid development of computer networks, the graphical user interface, that is, Graphic User Interface (GUI), has become a variety of different computing devices, such as personal computers (Personal Computer, PC), Essential functions for portable terminals, etc. At the same time, people are no longer satisfied with the text, voice and video communication based on the network, and begin to use the network to realize remote control, monitoring and computer supported cooperative work (Computer Supported Cooperative Work, CSCW), etc., and it has been more and more widely used. , including network multimedia conferencing, remote office, distance education, product demonstration and st...
