This question will analyze your understanding and the concepts learned during classes and labs to answer this question. What are applications of non-linear point operations on images? Describe how log transformation transforms an image? What is histogram equalization and how it improves an image? What are applications of histogram shaping? How image averaging removes noise in an image? What are applications of image differencing?

Point Operations:

                Point operations refer to running the same conversion operation for each pixel in a grayscale image. The transformation is based on the original pixel and is independent of its location or neighboring pixels.

There are two types of Point Operations.

1. Linear Point Operations
2. Non-Linear Point Operations

Before understanding the Non-Linear Point Operations, we should understand the concept of Linear and Non-Linear Functions.

Linear Function:

                Linear functions are those whose graph for input and output is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
