hi,

btw, the color conversion problem ( YUV -> RGB ) i've raised on that list was an error on my side : the object was not picking the right pixel, oops !!

the following formulas are allright :

• conversion from YUV to RGB
• r = 1.164*(y-16) + 1.596*(v-128);
• g = 1.164*(y-16) - 0.813*(v-128) - 0.391*(u-128);
• b = 1.164*(y-16) + 2.018*(u-128);
• conversion from RGB to YUV
• y = 0.257*r + 0.504*g + 0.098*b + 16
• u = -0.148*r - 0.291*g + 0.439*b + 128
• v = 0.439*r - 0.368*g - 0.071*b + 128
