T-61.5100 Digital image processing, Exercise 1/07 1. Suppose that a flat area with center at (x0, y0) is illuminated by a light source with intensity distribution i(x, y) = Ke−[(x−x0)2+(y−y0) ... 2]. The reflectance r(x, y) of the area is 1 and K = 255. If the resulting image is digitized using n bits of intensity resolution, and the eye can detect an abrupt change of eight shades of intensity between adjacent pixels, what value of n will cause visible false contouring? 2. A common measure of transmission for digital data is the number of bits transmitted per second (bit/s). Generally, transmission is accomplished in packets consisting of a start bit, a byte (8 bits) of information, and a stop bit. Using this approximation, answer the following: [Show More]
