Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a method for transmitting text blocks is provided. It should be noted that the steps shown in the flow charts of the accompanying 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.

[0027] figure 1 is a flowchart of a method for transmitting text blocks according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0028] Step S102, divide the pixels of the text block into multiple layers according to the frequency of occurrence of the pixels.

[0029] Specifically, the foregoing text blocks may be text blocks obtained by dividing an image into blocks. In an optional embodiment, the picture can be divided into blocks, ...

Embodiment 2

[0098] According to an embodiment of the present invention, an embodiment of a text block transmission device is provided, Figure 4 is a schematic diagram of a text block transmission device according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0099] A layering module 40, configured to divide the pixels of the text block into multiple layers according to the frequency of occurrence of the pixels.

[0100] The transmission module 42 is configured to sequentially transmit each layer of pixels according to the frequency of each layer of pixels from high to low.

[0101] As can be seen from the above, the above-mentioned embodiments of the present application divide the pixels of the text block into multiple layers according to the frequency of occurrence of the pixels through the layering module, and use the transmission module to sequentially process each layer according to the order of the frequency of occ...

Embodiment 3

[0129] According to an embodiment of the present invention, a processor is provided, wherein the processor is used to run a program, wherein the method for compressing and encoding a text block in any one of Embodiment 1 is executed when the program is running.

[0130] The serial numbers of the above embodiments of the present invention are for description only, and do not represent the advantages and disadvantages of the embodiments.

Abstract

The invention discloses a character block transmission method and apparatus. The method comprises the following steps: dividing pixels of character blocks into multiple layers according to the pixel occurrence frequency; and transmitting each layer of pixels according to the occurrence frequency of each layer of pixels in a sequence from high to low. By adoption of the character block transmission method and apparatus, the technical problem of relatively large bandwidth occupation in the character block transmission in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for transmitting text blocks. Background technique [0002] There is a big difference between the video sequence collected by the computer screen and the video sequence collected by the camera and other equipment. In computer screen images, there are text images in many scenes, for example: browsing the web, playing slideshows, etc., there will be a lot of text. In this paper, the text image is intercepted and divided into blocks according to a fixed size, and the obtained image block information is referred to as a text block. Based on its unique properties, text blocks can still maintain a relatively reasonable degree of distortion under a large compression ratio. [0003] Among the current mainstream compression algorithms (for example: H.264, H.265, JPEG), the effect of compressing text blocks is not ideal. For example, in video conferencing, rem...
