Problems solved by technology

[0004] In the compression method for text information in the related art, after distinguishing and identifying the text area, use a lossless or lossy, space domain or frequency domain compression algorithm to compress the text area as a whole. In this way, the text compression efficiency has not been optimized.

Abstract

The invention discloses an information compression / decompression method and device, and the method comprises the steps: dividing a to-be-processed text block into different text regions, and providinga precondition that the text block can be split into text lines for the subsequent line feature analysis of the text regions, thereby guaranteeing compression of text information through the distribution features of texts, and improving compression efficiency of text information. The compression efficiency of the text information is improved, and meanwhile, the transmission definition of the textinformation is improved.

Description

technical field [0001] This application relates to but not limited to information processing technology, especially an information compression / decompression method and device. Background technique [0002] With the popularization of cloud computing, virtual desktop and other technologies, it is necessary to transmit a large amount of remote data as quickly and clearly as possible to the user terminal for display through the network. In cloud desktop daily office-related scenarios, the screen content usually contains a large amount of text, and the clarity of the text content can significantly affect the comfort of human vision. Therefore, in common cloud desktop scenarios, text is used in lossless or Approximately lossless compression algorithm for processing. [0003] In the related art, a mainstream method for text compression is based on the limited distribution of pixel values ​​in the text area. After the text area is clustered to generate a palette, the palette index ...
