1.4、绘制直方图 OpenCV中内置的函数---calcHist: calcHist—计算图像直方图函数原型:calcHist(images, channels, mask, histSize, ranges, hist=None, accumulate=None) - images:图像矩阵,例如:[image] - channels:通道数,例如:0 - mask:掩膜,一般为:None - histSize:直方图大小,一般等于灰度级数 - ranges:...
直方图均衡化是一种图像处理方法,用来提高图像的对比度,本博客涉及到直方图的应用PYTHON+OPENCV2 如果一个图像的像素取值范围在很狭窄的一个区域内,那么图像的细节就不是那么的明显,如果可以将图像的像素分布范围均衡化,那么能够提高图像的对比度,如下图所示: 使用python+opencv2计算一幅图像的直方图,图像如下图: 由...
