Digital Signal & Image Processing is semester 7 subject of final year of computer engineering in Mumbai University. Prerequisite for studying this subject are Applied Mathematics. Course objectives for subject Digital Signal & Image Processing is to understand the fundamental concepts of digital signal processing and Image processing. To explore DFT for 1-D and 2-D signal and FFT for 1-D signal. To apply processing techniques on 1-D and Image signals.  To apply digital image processing techniques for edge detection. Course outcomes for subject Digital Signal & Image Processing On successful completion of the course learner will be able to:  Apply the concept of DT Signal and DT Systems. Classify and analyze discrete time signals and systems. Implement Digital Signal Transform technique DFT and FFT. Use the enhancement techniques for digital Image Processing.  Differentiate between the advantages and disadvantages of different edge detection techniques. Develop small projects of 1-D and 2-D Digital Signal Processing.

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values. 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 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; third, the demand for a wide range of applications in environment, agriculture, military, industry and medical science has increased.
