YUV is a color encoding system typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, thereby typically enablingtransmissionerrors or compression artifacts to be more efficiently mas...

RGB2YUV Reference 我发现一个超有用的 AI Noise Reduction Group 小组,参与论文讨论来加入小组一起学习吧 CMC:Color Matrix Correction 即色彩矩阵矫正。一般来说sensor 对光谱的响应(下图左),在 RGB 各分量上与人眼对光谱的响应(下图右)通常是有偏差的,而且图像数据经过ISP的AWB处理之后会存在较为明显的色偏,因...

1、YUV(亦称YCrCb)是被欧洲电视系统所采用的一种颜色编码方法。在现代彩色电视系统中,通常采用三管彩色摄像机或彩色CCD摄影机进行取像,然后把取得的彩色图像信号经分色、分别放大校正后得到RGB,再经过矩阵变换电路得到亮度信号Y和两个色差信号R-Y(即U)、B-Y(即V),最后发送端将亮度和两个色差总共三个信号分别进行...
