Task -2 [10 Marks] Histogram normalization is one of the common procedures to enhance the contrast of the image. Your task for this part is to: a) Create an image processing function which implements the histogram of an image b) Create an image processing function which implements the histogram normalization procedure to enhance the contrast of the image. c) Demonstrate the working of the code for histogram measurement in Part- a, by plotting the histogram of the 5 images that you acquire. d) Apply the procedure implemented in Part-(b) to enhance the contrast of these images. Analyse the histogram of the resultant contrast enhanced image. Demonstrate the results
