Fig: Fundamental Steps in Digital Image Processing Image acquisition: It could be as simple as being given an image that is already in digital form. Generally the image acquisition stage involves processing such scaling. Image Enhancement: It is among the simplest and most appealing areas of digital image processing.

Download PDF It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions (perhaps more) digital image processing may be modelled in the form of multidimensional systems.

Image processing. An image processing operation typically defines a new image g in terms of an existing image f. The simplest operations are those that transform each pixel in isolation. These pixel-to-pixel operations can be written: g(x, y) = t( f (x, y)) Examples: threshold, RGB → grayscale. Note: a typical choice for mapping to grayscale.

to processing digital images by means of a digital computer. Note that a digital image is composed of a finite number of elements, each of which has a particular location and value. These elements are called picture elements, image elements, pels, and pixels. Pixel is the term used most widely to denote the elements of a digital image. EXAMPLES.
