Ringing Effect in Image Processing

An image having uneven sharp edges is called a ringing effect image. It is also known as the overshoot effect.

The ringing or overshoot effect is produced by the edge enhancement filter. The solution to the ringing effect depends upon the parameter of the problem: if the cause is a low-pass filter, we can choose a different filter design. Where we can not replace the filter in case of a band-limited signal which results in difficulties in fixing the ringing artifacts.

What is Image Processing ?

Digital Image Processing is an on-demand technique and plays a crucial role in this evolving era. Digital Image Processing is a process that involves analyzing and manipulating images digitally via computer to make them more informative for human interpretation and picture information for tasks such as maintaining storage, fast transmission, and extraction of pictorial data. This is used in various domains such as automation, medicine, remote sensing, and more.

What are Digital images?

An image is a two-dimensional rectilinear of pixels that gives a pictorial representation of something. An image can also be defined as a two-dimensional function f(x,y) where X and Y are spatial coordinates, and f at any pair of coordinates (x,y) is called the intensity. When the x, y, and f are all finite then the image is called a digital image....

Digital Image Processing focuses on two major tasks: improvement of pictorial representation for human interpretation and Processing of image data for storage, transmission, and representation for autonomous machine perception....

Origin of Digital Image Processing

Digital Image Processing was first used in the newspaper industry. At that time images were sent by submarine cable between London and New York. In the early 1920s, the Bartlane cable picture transmission system was introduced which reduced the time requirement to transport a picture across the Atlantic from more than a week to less than three hours. The pictures are coded in specialized printing equipment, and after reaching the end they are reconstructed. Initial problems found in improving the visual quality of early digital pictures were related to the selection of printing procedures and the distribution of intensity levels....
