Basically, the idea behind enhancement techniques is to bring out detail that is obscured, or simply to highlight certain features of interest in an image. Mage enhancement is among the simplest and most appealing areas of digital image processing. Generally, the image acquisition stage involves per-processing, such as scaling, etc. Image acquisition could be as simple as being given an image that is already in digital form. This is the first step or process of the fundamental steps of digital image processing. This is the Image Processing Block Diagram image step by step as follow: Image Recognition Distinguish the objects in an image.Measurement of pattern Measures various objects in an image.Image retrieval - Seek for the image of interest.Image sharpening and restoration - To create a better image.Visualization - Observe the objects that are not visible.The purpose of image processing is divided into 5 groups.
Usually Image Processing system includes treating images as two-dimensional signals while applying already set signal processing methods to them. It is a type of signal dispensation in which input is an image, like video frame or photograph and output, may be image or characteristics associated with that image. Image Processing is a method to convert an image into digital form and perform some operations on it, in order to get an enhanced image or to extract some useful information from it. Here we discuss about the fundamental steps in Digital Image Processing and the Block Diagram of Digital Image Processing System with figure in step by step.
