Adaptive Thresholding Adaptive Method - It decides how thresholding value is calculated. cv2.ADAPTIVE_THRESH_MEAN_C : threshold value is the mean of neighbourhood area. cv2.ADAPTIVE_THRESH_GAUSSIAN_C : threshold value is the weighted sum of neighbour…
Adaptive Threshold 1. Otsu's Binarization: Using a discriminant analysis to partition the image into 2 classes C0 = {0, 1, 2, ..., t} and C1 = {t+1, t+2, ..., L-1} at which is the total number of the gray levels in image; (1). Let n be the total numb…

参考文档: Adaptive Thresholding for the DigitalDesk.pdf Adaptive Thresholding Using the Integral Image.pdf 一.问题的由来 一个现实: 当用照像机拍摄一副黑纸白字的纸张时,照相机获得的图像并不是真正的黑白图像.不管从什么角度拍摄,这幅图像实际上是灰度或者彩色的.除非仔细的设置灯光,否则照相机所拍摄的放在桌子上的纸张图像并不能代表原始效果.不像在扫描仪或打印机内部,想控制好桌子表面的光源是…

这篇blog,原来是西弗吉利亚大学的Li xin整理的,CV代码相当的全,不知道要经过多长时间的积累才会有这么丰富的资源,在此谢谢LI Xin .我现在分享给大家,希望可以共同进步!还有,我需要说一下,不管你的理论有多么漂亮,不管你有多聪明,如果没有实验来证明,那么都是错误的. OK~本博文未经允许,禁止转载哦! By wei shen Reproducible Research in Computational Science “It doesn't matter how beautif…
