RGB to YUV to RGB

i read somewhere that converting from RGB to YUV could be done with this

Y=.3R+.59G+.11B;

U=B-Y;

V=R-Y

but what is the conversion from YUV to RGB ?

Just treat it as three equations and solve it.

B=Y+U; R=Y+V; G=(Y-.3R-.11B)/.59;

Actually:

R = 1.164*(Y - 16) + crv*(V - 128) G = 1.164*(Y - 16) - cgu*(U - 128) - cgv*(V - 128) B = 1.164*(Y - 16) + cbu*(U - 128) // where: /* For SMPTE 170M (NTSC;MPEG-1) */ crv = 1.596f; cbu = 2.018f; cgu = 0.391f; cgv = 0.813f;

Assuming input and output is between 0 and 255. You also need to be warry over overflow/underflow and clamp accordingly.
