Image Processing is a computer system that processes digital images. It is often used to improve the quality of pictures, modify the appearance of an image, or generate new images. Image processing technology has a variety of applications in the world of computers.
In its broadest definition, image processing is the alteration of a digital image. This may be as simple as resizing or cropping the image, or more complex such as adding text or adjusting the brightness and contrast. This can be done manually with the aid of a graphics editor, or automatically with the use of image processing software.
When image processing is used, pixels are the basic unit of measure. Pixels are individual points of light or shade in an image, and computers can manipulate these individual points. Image processing algorithms can be used to manipulate the individual pixels to create a desired effect, or to analyze the entire image for qualities such as color or texture.
Image processing is widely used in the world of computers. Common applications include digital editing of photographs, 3D computer graphics, medical imaging, and satellite image analysis. The technology is also used in many areas of science, engineering, and business. For example, it can be used to examine the surface of a product for flaws or imperfections, to detect objects in a motion picture or video, or to recognize handwriting.
In recent years, the applications of image processing have expanded as technology advances and many more complexities can be manipulated and explored. Various new techniques have been developed for handling images, including artificial intelligence and machine learning techniques. This is opening up a whole new range of possibilities for application of image processing technology.
