libobs: Rework RGB to YUV conversion Browse files RGB to YUV converison was previously baked into every scale shader, but this work has been moved to the YUV packing shaders. The scale shaders now write RGBA instead. In the case where base and output resolutions are identical, the ...
一般人们所讲的YUV大多是指YCbCr。 YCbCr的两种常用格式[3]: 1)ITU-R BT.601 conversion 缩放到具有上下动态裕量的8bit,平移后可以用无符号数表示。 2)JPEG conversion 使用完全的8bit输出表示每一个分量。 相比RGB,YUV或者YCbCr的优点是减少通道之间的相关性。可以方便的对色彩进行阈值处理;简化了彩色图像的...
大M的小世界 [原]又一个yuv和rgb的转换公式 手上一套arm汇编的yuv to rgb代码,用的就是这个公式,在很多地方,也看到是用这个,记录于此。 RGB to YUV Conversion Y = (0.257 * R) + (0.504 * G) + (0.098 * B) + 16 Cr = V = (0.439 * R) - (0.368 * G) - (0.071 * B) + 128...
