cv2.applyColorMap函数通过查找一个内置的颜色映射表(colormap),将输入的灰度值转换为对应的RGB颜色值。OpenCV提供了多种内置的colormap,如COLORMAP_JET、COLORMAP_HOT等,每种colormap都有不同的颜色渐变方式。在转换过程中,函数会根据输入的灰度值在colormap中查找对应的颜色,并将该颜色赋值给输出图像的相应像素。
python常常用opencv模块来处理图像。 importcv2ascv 读取图片:imread() 默认按照彩色三通道读取: img= cv2.imread(path) 读取灰度图: img= cv2.imread(path, cv2.IMREAD_GRAYSCALE) 色彩空间转换:cvtColor() #彩色图转灰度图gray= cv.cvtColor(img, cv.COLOR_BGR2GRAY)#彩色图转HSV [255,255,128]img2= cv...
