YUV to RGB formula：
/* R = Y + 1.14V，G = Y - 0.39U - 0.58V，B = Y + 2.03U YUV对应YCbCr
r = y + 1.14*cr;
g = y - 0.39*cb - 0.58*cr;
b = y + 2.03*cb; */
/* YCbCr与RGB的关系 */
r = 1.164*(y-16) + 1.596*(cr-128);
g = 1.164*(y-16) - 0.813*(cr-128) - 0.392*(cb-128);
b = 1.164*(y-16) + 2.017*(cb-128);

/* r=1.0*y+1.402*(cr-128) ;
g=1.0*y-0.34413*(cb-128)-0.71414*(cr-128);
b=1.0*y+1.772*(cb-128);*/

Sometimes All White or Black
imshow(uint8(A));
If the format is double, the value will be 0 or 1.
Or U can: imshow(I,[])
