在opencv3.0中, cv::IMREAD_COLOR 解析jpg时候,由cv::JpegDecoder解码得到一个RGB图像,然后由icvCvt_RGB2BGR_8u_C3R() 函数交换R和B空间,得到BGR格式的彩色图。 cv::IMREAD_GRAYSCALE 这个图像由cv::JpegDecoder解码...
IMREAD_REDUCED_COLOR_2 = 17, //!< If set, always convert image to the 3 channel BGR color image and the image size reduced 1/2. IMREAD_REDUCED_GRAYSCALE_4 = 32, //!< If set, always convert image to the single channel grayscale image and the image size reduced 1/4. IMREAD_REDUC...
