RGBToGray bug?

I use RGBToGray to convert a color image to a gray scale image, but I found the result was very strange, if I convert a white color image whose pixel values are (255,255,255), I got a gray scale image with all values 254 ( not 255), why?

P.S. I used the latest IPP.

Hello,

thank you for your report, we will analize the code. It seems that optimized version of this function suffer from lack of precision of color conversion coefficients.

Regards,
Vladimir
