DCT
实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见,经DCT低通滤波后,图像变得很模糊。因为DCT是FFT取其实部,能量减少,因此图像变得很模糊,没有经FFT滤波后的效果好。
经DCT高通滤波后的图像:
经DCT高通滤波后,图像的低频部分被滤除掉,图像变黑,只有边缘的痕迹可见。

codeofroughset
粗糙集的基本算法,包括数据补齐,属性约简,值约简,规则生成,非常实用。(Rough set theory is a new mathematical approach to imperfect knowledge. The problem of imperfect knowledge has been tackled for a long time by philosophers, logicians and mathematicians. Recently it became also a crucial issue for computer scientists, particularly in the area of artificial intelligence. )
