2-6-2读取特定彩色图像像素坐标的BGR值 参考ch2_2.py第4行,使用如下指令读取图像。 img = cv2.imread(“jk.jpg”) 假设想获得(169, 118)的BGR值(这是采用OpenCV坐标概念),可以使用如下指令。 px = img[169, 118] 上述用彩色图像读取时,返回的是Numpy模块的数组数据类型(numpy.ndarray)。 程序实例ch2_4....

opencv中默认的色彩空间是RGB颜色空间,但是顺序是BGR,所以此文中均已BGR颜色空间来说明。仅表示BGR的顺序,并没有其他含义。 HSV颜色空间 HSV(Hue, Saturation, Value)是根据颜色的直观特性由A. R. Smith在1978年创建的一种颜色空间, 也称六角锥体模型(Hexcone Model)。色调H用角度度量,取值范围为0°～360°,...
