Part1. Image Processing. A gray scale image is given as follow, where 0 represents black and 15 represent white pixels: [0 0 0 15 15 4 0 0 15 1 1 10 0 15 4 0 0 2 15 10 2 12 11 11 a) What is the debt of the gray-scale color (number of bits)? b) Propose a kernel that can be used to detect lines with 45 c) Apply your proposed kernel (analytically) to the above image and compare your result to MATLAB output using conv2 function
