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。
(The DCT of image high-pass, low pass filter and compared with the Fourier transform.)

为对细管中的细胞作图像分析,所以就先作了一个管道区域分割的程序,用的的竖直直线和水平直线腐蚀的方法,比较基础和大家分享讨论^_^
其中autothreshold是一个自动阈值分割的程序
(For the pairs of thin tube of cells for image analysis, so we made a first pipe region segmentation process, using the vertical and horizontal straight line method of corrosion, compare the basis and share the discussion ^ _ ^
One autothreshold is an automatic thresholding procedure

Wavelet-Denoise
是一个小波降噪的程序,里边包括了小波降噪的实例,有三种方法:默认阈值去噪;软硬阈值的去噪;强制性去噪。(Is a wavelet noise reduction program, including the inside of the Wavelet Transform instance, there are three ways: the default threshold denoising hard and soft threshold de-noising mandatory de-noising.)
