Problems solved by technology

If the existing lossless compression method is used, once the resolution of the image increases, the encoder will have to spend a long time and a large amount of storage space to process it into a high-quality image
In other words, the existing lossless compression methods have the problems of low computational efficiency due to high computational complexity and huge temporary storage space required

Abstract

The invention discloses a lossless image compression method, which is used for processing an image with a plurality of pixels, wherein the image width of the image is W. The lossless image compression method comprises the following steps of: selecting N continuous pixels from the image, wherein N is a positive integer more than or equal to 2 and less than the image width W; executing differentialpulse code modulation means to obtain N nonnegative difference values corresponding to the N pixels according to values of the N pixels; computing coding parameters according to the N nonnegative difference values; and coding the N nonnegative difference values according to the coding parameters.

Description

technical field [0001] The invention relates to a distortion-free image compression method, in particular to a distortion-free image compression method requiring less memory space. Background technique [0002] With the advancement of electronics and information technology, the development of technologies for processing and displaying images on computers or various electronic devices is becoming more and more common. Early electronic information technology could only store or process digital images with relatively low pixels. However, people's demand for high-quality images is increasing, and how to process and store high-quality images has become a very hot focus. In order to obtain high-quality images, a lossless compression method is often used in image compression. [0003] However, a high-quality image without distortion needs to store relatively high pixels, which also poses a big challenge to the calculation speed of the calculator and the capacity of the storage me...
