Image Processing

Problem 2 (10 points) Assume that a Gaussian pyramid of an image is being created. Smoothing is done using binomial kernel 1 4 6 4 1 16 The decimation factor is r-2. Figure below shows the analysis stage for a portion of a single image row a) b) Calculate the missing values A, B, C and D. Show all the steps in the calculations! Which values must be computed to find the value of D?
