Q \# 3 [3 Marks]: a) Consider a rectangular 6-bit gray image with 512 row pixels. If this image is stored in a digital computer using 3. 145728 Mbits: 1 - determine the number of intensity levels used to represent each pixel 2 - find the number of column pixels in this image b) For the same image defined above, if the number of possible gray (intensity) levels is increased to 256, find the number of storage bits required to store this image. ANSWER: a) 1. L=2k26>64 - The grayscale [063] 2 - Size =mnk3145728=512n6 3145728=n1024 30723145728=n1024 b) 2k=256k=8 Storagesize=mxnk51210248=41943074bytes 444194304Mbits Q \# 4 [2 Marks]: What are the two steps required to convert an analog image to a digital image, explain briefly each step. ANSWER: I - sampling:o discritization of spacial values (x,y) 2 - quantizationso digitizing the so amplitude values of (x,y)
