Contrast Stretching: Write your own program to implement a piecewise linear transformation for contrast adjustment using MATLAB/C/C++/Java/Python. The piecewise linear transformation function is illustrated in Fig. 1. Apply the transformation to an 8-bit gray-level image (a low-contrast image of your choice) to adjust its visual appearance. Experiment the transformation with three different sets of parameters: (ri, si) & (r2, s2). on to an8-itgrayovel imaont tne transformation with three (1) Show the original image and its intensity transformed images; (2) Describe specific change(s) (in terms of visual appearance) in the intensity adjusted image after each transformation (of different set of parameters) is applied; (3) Turn in your implementation codes in a separate file.
