Q. 3. (a) Discuss Generalized Hough transform, and express it in an algorithmic form using pseudo code. (4 Points) (b) Using a 5x5 Hough array with the integral values of each of the parameters a and b ranging between -2 to 2, show that the points (-1, 1), (-2, 7), (0, -1), (1, 1), (2, 7) fall on a second degree curve y= a.x + b, and find the values of a and b. Ignore the cells that are not in the range. (2 Points)
