Image Compression and Encryption of MATLAB Design and Implementation

随着信息爆炸时代的到来,图像信息的高效与安全传输问题迫切需要解决。从系统的角度出发,利用MATLAB平台,设计并实现了一种新的图像压缩与加密方法。首先分析了SVD图像压缩、JPEG图像压缩、混沌系统和DNA编码运算解码等原理和方法;然后基于MATLAB GUI界面开发方法,把多个相关模块串联到一起,进而设计了融合图像压缩、加密、编码、传输的数字通信系统。该研究对图像高速传输与安全性能的提高具有重要的实际意义,对于同类设计具有一定的指导作用。

With the advent of the era of image information explosion,high speed and security of image information transmission are becoming more and more urgent.From the perspective of the system,a new image compression and encryption method is designed and implemented by using MATLAB platform.The principles and methods of SVD and JPEG image compression,chaotic system and DNA coding operation and decoding are analyzed,and various modules are connected in series using MATLAB GUI,so as to design a digital communication system that integrates information source encoding and decoding,modulation and demodulation,encryption and decryption,and noise superposition.This research has important practical significance for the improvement of high speed and security performance of image transmission,and has a certain guiding role for similar designs.
