Understanding Discrete-time Signal Processing : Lecture Notes

Digital image processing deals with manipulation of digital images through a digital computer. It is a subfield of signals and systems but focus particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. The input of that system is a digital image and the system process that image using efficient algorithms and gives an image as an output. The most common example is Adobe Photoshop. It is one of the widely used applications for processing digital images. This book gives you the knowledge of widely used methods and procedures for interpreting digital images for image enhancement and restoration and performing operations on images such as (blurring zooming sharpening edge detection etc.). It also focuses on the understanding of how the human vision works. How do human eye visualize so many things and how do brain interpret those images?  The book also covers some of the important concepts of signals and systems such as (Sampling Quantization Convolution Frequency domain analysis and providing information Security using image processing).
