Pixel

Umair Uddin
If i am selecting a pixel from any gray scale image like this

d = D(u,v) ; where u,v are loop counters .

More Precisly the question is what D(u,v) will return . Is it the
intensity of the pixel or the position of the pixel.
If it is the position so should i save the result in the single
variable d ? Please guide . Thanks in advance

D is an image.

D(u,v) suppose to return content (intensity in case of grayscale image)
of D at location (u,v).
