本课题研究的主要内容是在空间域直接处理图像的基础上，几种典型的变

换域快速算法分析与研究及这些快速算法的程序设计实现。还研究了图像增强

中的变换域处理方法，主要针对几种典型变换域滤波器及其程序实现；最后对

小波变换的算法分析及在图像压缩中的应用进行了理论研究。-This task includes a series of speedy arithmetic analysis and their programme

implement in frequency domain after spatial domain.It also includes image

enchancement in the frequency domain that is several frequency-domain filter.At

last the task includes the arithmetic of wavelet transformation and its application in

image copression.
