基于Matlab的变换域数据压缩实验设计

On the Experiments Designing for Data Compression Coding in Transformation Domains Based on Matlab

变换域编码,是电子信息专业课"数据压缩"中限失真信源编码理论重要内容,具有应用的广泛性和理论上的抽象性,需要根据教学内容设计适当的实验项目配合。作为工程技术应用语言,Matlab具有丰富的信息处理函数资源、简单易学,适合于变换域语音、图像数据压缩方案设计,成为实验设计优先选择的编程工具。

Experiments, as one important sector in teaching procedure, is beneficial to students on reviewing what they have learned in class, and can strengthen the ability to solve practical problems by the application of their knowledge. Transform coding, as one of the essential theory included in the course of Data Compression, has a variety of application in speech and image compression and its principles are so abstruse that appreciate experiments are needed to reinforce teaching effects. Hence, Matlab should be used in the design of such projects because of the characteristics of having the easiness to understand and profound source of functions on information processing.
