Image Concepts and Principles

It is important to understand certain key concepts related to understanding computer graphics and image processing. These important concepts include,

• Pixel Art: The images are edited at the pixel level. This form of digital art is created using raster graphics software and a few examples of pixel art include computer video games, mobile phone games, etc.

• Vector Graphics: Vector graphics contains encoding information about shapes and colors that make up the image and allows more flexibility in rendering. This form of graphic format represent images as an array of pixels and mostly used in representing photographic images.

• Raster Graphics: A raster graphics image is a structure representing a rectangular grid of pixels or points of colors, viewed via a monitor or other display unit. It is also called bitmap images and stored in image files with varying formats.

• Pixel: A pixel is a single point and is an element of the picture, and normally represented using dots or squares. Each pixel is a sample of the original image and varies in terms of intensity. ...
... Typically the pixel has three components such as red, blue and green.

• Graphics: Graphics is a visual representation of an object to illustrate an image. Graphics has the ability to combine text, color, pictures, symbols, etc. The representation of graphics in the computer is done through the monitor.

• Rendering: The process of generating an image from a model is called rendering. This is a computer program built into the graphics software and produces the final video output.

The area of computer graphics or digital image processing is a major field under computer science and this area provides the reader with comprehensive studies on the synthesis and manipulation of digital content.
