What is image smoothing? Try to explain the basic principle of mean filtering.

Practice Test Question #1: You want to solve a simplified 4x4 version of the Sudoku game with the following grid configuration (image attached): (a) Show the first ten steps of backtracking search on the sample provided, where you order the variables in increasing order first by row, then by column (in English reading-order), and the values from lowest to highest (1 to 4). Recall that backtracking search uses a depth-first strategy to expand the search tree. (b) Show the first ten steps of backtracking search on this problem with one-step forward checking, with the same variable ordering.

Demonstrate the effectiveness of histogram equalization as a powerful adaptive contrast enhancement tool using Matlab. a. Compute and display the histogram of a grey-scale image with and without using the built-in functions. b. Equalize the histogram with and without using the built-in functions. c. Construct the histogram equalized image. d. Compare the equalized and original images and histograms.

an input color RGB image with the height of 200 and the width of 200 has entered a Convolutional Neural Network that has the convolutional layer with 50 filters each with the size of 3x3. How many parameters does this convolutional layer (filter parameters and biases altogether) have?
