RGBToYCbCr422 将RGB图像转换为YCbCr图像,采样为4:2:2。 此函数将伽马校正的R'G'B'图像src转换为Y'Cb'Cr'图像dst,采样格式为4:2:2。其中转换公式与函数RGBToYCbCr相同。 像素阶图像的转换缓冲区的位深度降低为每像素16位,而源缓冲区的位深度为24位。 函数接口声明如下:

i need convert RGB image to YCbCr colour space, but have some colour shift problems, i used all formulas and got the same result. Formula in python cbcr[0] = int(0.299*rgb[0] + 0.587*rgb[1] + 0.114*rgb[2]) #Y cbcr[1] = int(-0.1687*rgb[0] - 0.3313*rgb[1] + 0.5*rgb[2]...
很像altera VIP IP核中的CSC;另外我还找到了Xilinx的两个版本的RGB2YCbCr的VHDL代码,一个是Color-Space Converter: RGB to YCrCb,XAPP930,这个代码包还有对应的说明文档,这些都能在Xilinx官网上下载到;另一个是在国内某论坛上下载的,相对简单一点,而且思路清晰,也是Xilinx公司的,于是我就选择了这个版本,细细研读...
前面已经讲到由单片CCD彩色摄像机得到Bayer Raw Data(Bayer格式视频数据),并且通过插值算法得到RGB数据;或者通过三片式CCD彩色摄像机直接得到RGB数据。同时我们也常听到YUV或者YCbCr视频数据,这些不同的概念直接有什么关系呢,今天就关于这个话题做详细介绍。首先,这里

It would be great to see more variations on the RGBToYCbCr functions (RGB to 4:4:4 YCbCr). Specifically, 709HDTV versions in both packed (C3) and planar (P3) varieties. Also, support for BGRtoYCbCr in each variation would be very helpful to us. A few specific functions that would be...
