DIGITAL IMAGE PROCESSING: With Matlab Example

Digital signal processing is the subject of engineering in which we process the digital signal with the help of computer, perform some mathematical operation upon signal and extract desired information from the signal. Digital Image processing is the branch of digital signal processing in which first we convert an image into the digital signal with the help of a digital camera and computer then store this image into a computer. Once image is stored into the computer then it is converted into the two dimensional matrix of numbers. Now we can perform any mathematical operation with these numbers and can modify or transform these numbers in to the desired way and can extract an information. This process of modifying or extracting the desired information from digital image is called digital image processing.
