Embodiment 1

[0035] According to an embodiment of the present invention, an embodiment of an image coding and compression method is provided. It should be noted that the steps shown in the flow charts of the drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0036] figure 1 is a schematic flow chart of an image encoding and compression method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0037] Step S102, divide the image to be transmitted into blocks, and classify the macroblocks after the block division of the image to be transmitted according to preset conditions;

[0038] Step S104, encoding and compressing the classified macroblocks according to the encoding and compression mode corresp...

Embodiment 2

[0067] According to another aspect of the embodiments of the present invention, a method for image decoding and compression is also provided, image 3 is a schematic flowchart of a method for image decoding and compression according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps:

[0068] Step S302, splitting the received code stream according to the corresponding type at the decoding end;

[0069] Step S304, correspondingly decode the code streams of each layer obtained after splitting;

[0070] Step S306, displaying the decoded code streams of each layer.

[0071] In the embodiment of the present invention, different encoders are used to compress the low-frequency sub-band to achieve a smaller code rate to meet the demand for a small bandwidth.

Abstract

The invention discloses a method, device and system for image coding and decoding compression. The method comprises the following steps: performing block division for an image to be transmitted, and classifying macro blocks of the image to be transmitted after being subjected to block division based on preset conditions; performing coding compression for the classified macro blocks based on a coding compression mode corresponding to the type of the macro blocks; and separately transmitting the macro blocks that are subjected to coding compression as each layer of code stream. According to themethod, device and system disclosed by the invention, the technical problem that the image is low in transmission efficiency in the case of bandwidth limitation as the prior art lacks a scheme of breaking the bandwidth limitation and implementing image transmission through progressive compression can be solved.

Description

technical field [0001] The present invention relates to the application field of image processing technology, in particular, to a method, device and system for encoding, decoding and compressing images. Background technique [0002] With the rapid increase of network users, narrow bandwidth is the bottleneck of network transmission. For the limitation of bandwidth, the progressive compression transmission of lossless compression can meet the needs of customers. First, the outline of the overall image is transmitted, and then the data is gradually transmitted. Image Quality. [0003] However, in the prior art, there is a lack of a solution for how to break through the bandwidth limitation and realize image transmission through the realization of progressive compression. [0004] Aiming at the above-mentioned problem of low image transmission efficiency under the condition of limited bandwidth due to the lack of a solution to break through the bandwidth limitation through pro...
