Identify correct position of mustaches?

how to identify the correct position for mustaches ?
i use this code with the help of net.
for i in range(mostache.shape[0]):
for j in range(mostache.shape[1]):
if(mostache[i,j,3]>0):
fullimg[y+i,x+j,:]=mostache[i,j,:-1]
but from this mustaches does not fit perfectly it is somewhat on the nose not below the nose. so how can i correct it?

hey @anuj_singla8 ,
these locations / positions depend upon your haarcascade detection.
so based on that detection , then you need to alter it somewhat by yourself. and then you can use that to paste you moustache there and it will work.
