“MATLAB is a high-level language and interactive environment that enables you to perform computationally intensive tasks faster than with. The purpose of this tutorial is to gain familiarity with MATLAB's Image Processing. Toolbox. This tutorial does not contain all of the functions available in MATLAB. Processing half of the Computer Graphics and Image Processing course unit. .. Such a histogram is called the probability density function (pdf) and reflects the.
Image processing Image processing is the technique to convert an image into digital format and perform operations on it to get an enhanced image or extract some useful information from it. Changes that take place in images are usually performed automatically and rely on carefully designed algorithms. Image processing is a multidisciplinary field, with contributions from different branches of science including mathematics, physics, optical and electrical engineering. Moreover, it overlaps with other areas such as pattern recognition, machine learning , artificial intelligence and human vision research. Different steps involved in image processing include importing the image with an optical scanner or from a digital camera, analysing and manipulating the image data compression, image enhancement and filtering , and generating the desired output image. The need to extract information from images and interpret their content has been the driving factor in the development of image processing. Image processing finds use in numerous sectors, including medicine, industry, military, consumer electronics and so on.

What is a digital image? A digitised image is represented as: Each element in the array is referred to as a pixel or an image element.
When an image from another directory has to be read, the path of the image has to be specified. Semicolon ; at the end of a statement is used to suppress the output. These images can be downloaded from the EFY website and stored in the current working directory.
