Part 3: Image Scanning 2

Assume a scanner has 4 x 4 resolutions, i.e. only 16 dots. The numbers in the cells are the intensity / brightness samples measure by the scanner, which has gray scale with 256 quantization levels ( 0 255) using 8 bits.

200.2	100.7	112.4	115.8
182.3	40.5	23.9	90.6
77.2	156.8	134.9	8.2
35.4	128.1	127.6	12.5

1.Find the quantized decimal values, e.g., scanned value 7.9 should be quantized to 8.
