Digital Image Processing means processing digital image by means of a digital computer. We can also say that it is a use of computer algorithms, in order to get enhanced image either to extract some useful information. Show Image processing mainly include the following steps:1.Importing the image via image acquisition tools; What is an image?An image is defined as a two-dimensional function,F(x,y), where x and y are spatial coordinates, and the amplitude of F at any pair of coordinates (x,y) is called the intensity of that image at that point. When x,y, and amplitude values of F are finite, we call it a digital image. Types of an image
A 16 bit format is actually divided into three further formats which are Red, Green and Blue. That famous RGB format. Image as a MatrixAs we know, images are represented in rows and columns we have the following syntax in which images are
represented: The right side of this equation is digital image by definition. Every element of this matrix is called image element , picture element , or pixel. DIGITAL IMAGE REPRESENTATION IN MATLAB:In MATLAB the start index is from 1 instead of 0. Therefore, f(1,1) =
f(0,0). PHASES OF IMAGE PROCESSING:1.ACQUISITION– It could be as simple as being given an image which is in digital form. The main work involves: OVERLAPPING FIELDS WITH IMAGE PROCESSINGAccording to block 1,if input is an image and we get out image as a output, then it is termed as Digital Image Processing.
