The module explains how digital images are represented in computers and explores the trade offs between image quality and file size. additionally, students will gain insights into different image file formats and compression techniques used to store and transmit digital images efficiently.

This module focuses on image enhancement techniques, essential for improving visual quality and extracting useful information from images. students will learn about various enhancement methods, including contrast stretching, histogram equalization, and noise reduction. Very simple way of improving image quality, either doing a simple linear stretch or contrast stretch, contrast enhancement by histogram stretching, that means histogram stretching. Use one of the two basic approaches of gray level slicing: approach 1 – all gray levels in the range of interest are displayed using a high value and the rest using a low value.

This document discusses image enhancement techniques in digital image processing. it defines image enhancement as modifying image attributes to make an image more suitable for a given task. Comprehensive guide to image enhancement, covering spatial domain point operations, histogram equalization, and frequency domain filtering like unsharp masking. Study of the subject is motivated by three major applications. the first application is in improvement of pictorial information for human perception i.e. enhancing the quality of the image so that the image will have a better look. The next step is image enhancement, which is one among the simplest and most appealing areas of digital image processing. basically, the idea behind enhancement techniques is to bring out detail that is obscured, or simply to highlight certain features of interest in an image.
