A Method of Simultaneous Transmission of Multiple Images Based on Information Hiding

Abstract

The invention discloses a method for transmitting multiple paths of images at the same time based on information hiding. The method for transmitting the multiple paths of images at the same time based on information hiding comprises the steps that the multiple paths of images are compressed respectively according to a specified compression ratio, one path of image which is closest to an index is selected, compression ratios are distributed to the other paths of images automatically according to objective evaluation indexes of the images, and the other paths of images are compressed at the same time according to the distributed compression ratios, wherein the compression ratios are always larger than the compression ratio of the first path of image; relevant compression information of the multiple paths of images is extracted and is hidden in the first path of image, then compression is conducted according to the specified compression ratio, the formats of the data of the images with different compression ratios are unified, the data of the images are then transmitted by several paths, the number of the paths of data transmission is not larger than the number of the paths of the images, and the overall transmission rate is reduced obviously. According to the method for transmitting the multiple paths of images at the same time based on information hiding, by means of the difference of the compression performance of the multiple paths of images, the compression ratios are distributed in a self-adaptive mode, the defects of a conventional technique for transmitting multiple paths of images are overcome, and on the premise that the quality of the multiple paths of images meets requirements, the actual compression ratio can be improved all the time, and pressure of a data transmission system is reduced.

Description

technical field [0001] The invention relates to a method for simultaneously transmitting multi-channel images based on information hiding, in particular to a method for compressing and transmitting images, and belongs to the technical field of data communication. Background technique [0002] Data transmission and image processing are important research topics in the field of communication at present. With the development of technology, the number of sensors continues to increase, and the acquired image is not only a single image, but also includes many images, such as multi-spectral images, hyperspectral images, there are many images to be transmitted, visible light images are also multi-channel transmission question. [0003] At present, most of the methods for transmitting multi-channel images are to transmit each channel separately, and there is a lack of effective joint processing and transmission methods. Using a single-channel image processing method to process mult...
