4 contains reference colors that are lightened or darkened to have a luminance comparable to the camera colors. Depending on what color model is used the color saturation may or may not be a good match to the camera values. Choices are1. HSL (default),2. HSV,3. xyY, and4. L*a*b*...
类型:颜色空间转换包括但不限于BGR到灰度、BGR到HSV、BGR到Lab等。 应用场景:在人脸识别、自动驾驶、医学影像分析等领域,颜色空间转换是预处理步骤中非常重要的一环。 解决方法 如果你遇到“cv2.cv2没有属性‘COLOR_BGR2GREY’”的问题,可以尝试以下几种解决方法: ...

颜色模型指的是某个三维颜色空间中的一个可见光子集,它包含某个色彩域的所有色彩。一般而言,任何一个色彩域都只是可见光的子集,任何一个颜色模型都无法包含所有的可见光。常见的颜色模型有RGB CIECMY/CMYK、(HSK NTSC、YcbCr、HSV 等。 BGR/RGB <-> HLS/HSV <-> GRAY <-> BINARY ...
