سوال کتاب گنزالس
Only the registered members can see the link
و جواب اون مطابق زیر است:
The image in question is given by
(f (x,y ) = i (x,y )r (x,y
= 255e −[(x−x0)2+(y−y0)2] ×1.0
= 255e −[(x−x0)2+(y−y0)2]
A cross section of the image is shown in Fig. P2.7(a). If the intensity is quantized
using m bits, then we have the situation shown in Fig. P2.7(b), where
G = (255 +1)/2m. Since an abrupt change of 8 intensity levels is assumed to
be detectable by the eye, it follows that G = 8 = 256/2m, or m = 5. In other
words, 32, or fewer, intensity levels will produce visible false contouring.
لطفا در مورد جواب توضیحات بیشتری بفرمائید.
با سپاس فراوان
