Hi,
I think there is a bug in IPP function "ippiYCbCr411ToBGR_8u_P3C4R" when it converts saturated YCbCr 411 values to RGB values. When an image is saturated, its YCbCr values are Y=235, Cb=128, and Cr=128. In this case, after conversionis done, the RGB values are all 254, instead of 255.
I am using IPP 7.0.6.278
I attached my sample codes, and the output of my sample codes are shown as below:
dst[ 0]=254
dst[ 1]=254
dst[ 2]=254
dst[ 3]=0
dst[ 4]=254
dst[ 5]=254
dst[ 6]=254
dst[ 7]=0
dst[ 8]=254
dst[ 9]=254
dst[10]=254
dst[11]=0
dst[12]=254
dst[13]=254
dst[14]=254
dst[15]=0
Does anyone else ever encounter the same issue?
