Unformatted text preview: sigma_r: Intensity (range) standard deviation parameter. sigma_d: Spatial (domain) standard deviation parameter. N: Spatial neighborhood parameter. It controls how many pixels are included in the neighborhood. The size of the neighborhood will be [2N+1 x 2N+1]. img_bilateral: Output image. Problem 2: (50 points) The histogram of an image is given as below. (a) Draw the histogram equalization function for this image. 0.4 0.6 1 A A/2 r p(r) (b) What would be new value of a pixel with intensity 0.5 after histogram equalization is applied? (c) What would be the histogram of the output image when the following transformation is applied to the image? (d) (Bonus 10 points) If we would like to obtain an image with the following histogram, what should be the mapping applied to the input image. 0.4 0.8 1 1 1/2 r T(r) 1 r T(r) 0.5 1...
