IV B.Tech I Semester Examinations,November 2010 DIGITAL IMAGE PROCESSING Electronics And Communication Engineering Time: 3 hours Max Marks: 80 Answer any FIVE Questions All Questions carry equal marks ????? 1. (a) What is meant by Image Filtering and Restoration? (b) Draw the appropriate Digital image restoration system.
[8+8]
2. Develop an algorithm for converting a one pixel thick, 8-connected path to 4connected path. [16] 3. A binary erasure channel is one in which there is a finite probability β that a transmitted symbol will not be received. The channel has three possible outputs: a0, an erasure (no received symbol), and a1. These three outcomes form the three rows of the binary erasure channel matrix. 1−β 0 β Q = β 0 1−β (a) Find the capacity of the channel. (b) Would you prefer a binary symmetric channel with a 0.125 probability of error or an erasure channel with probability of erasure β = 0.5 ? [16] 4. Explain in detail about the CMY and HIS color spaces.
[16]
5. What is Thresholding? Explain about Local Thresholding.
