代码说明:

  数字图像快速傅里叶变换(FFT)。将图像转化成二维灰度图像后再做FFT变换,并输出变换后的幅值图。(Digital image fast Fourier transform (FFT).The image is transformed into a two-dimensional gray level image and then the FFT transformation is made, and the amplitude diagram is output after the transformation.)

  • OTSUMultiThre
    1.本程序功能包含显示直方图,OTSU的单值分割,OTSU的二值分割,OTSU的三值分割 2.在OTSU的分割时,通常情况下我们是通过类间方差得到一个分割阈值,但是有时候我们需要得到各灰度级别的目标,那么采取多值分割是 很必要的,通过改进得到OTSU的多值分割方法 3.本程序另外还有显示直方图,计算程序运行时间,处理结果以新的窗口显示等细节,这部分适合MFC初学者。(1. This procedure shows the histogram feature, OTSU single segmentation, OTSU binary segmentation, OTSU three segmentation 2. OTSU segmentation, it is usually the case we are through the between-cluster variance by a partition threshold , but sometimes we need to be the gray level of the target, then the multi-segmentation is necessary, through improved access to multi-OTSU segmentation methods 3. This procedure in addition to show the histogram to calculate run time, treatment the results of a new window display the details of this part of MFC for beginners.)
