Image Processing

Image Processing is the semester 5 subject of IT engineering offered by Mumbai Universities. Prerequisite for studying these subject is Mathematics and Statistics.

As images are two dimensional signals, the single dimensional Digital Signal Processing fundamentals. Course Objectives of the subject Image Processing are as follows the course will help the students to get familiar with Fundamental concepts of a digital image processing system. Concepts of image enhancement techniques. Various Image Transforms. Compression techniques and Morphological concepts. Various segmentation techniques, and object descriptors. Color models and various applications of image processing. Course Outcomes of the subject Image Processing are as follows Students should be able to remember the fundamental concepts of image processing. Explain different Image enhancement techniques. Understand and review image transforms. Analyze the basic algorithms used for image processing &image compression with morphological image processing. Contrast Image Segmentation and Representation. Design & Synthesize Color image processing and its real world applications.
Digital image processing is the use of a digital computer to process digital images through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions (perhaps more) digital image processing may be modeled in the form of multidimensional systems. The generation and development of digital image processing are mainly affected by three factors: first, the development of computers; second, the development of mathematics (especially the creation and improvement of discrete mathematics theory); third, the demand for a wide range of applications in environment, agriculture, military, industry and medical science has increased.
