Digital Imaging Procesing Techiques

Image Processing Image processing is any type of signal processing, such as a picture or video frame, and the output of the image processing can be an image, or a series of features or parameters associated with the image. Most image processing techniques involve treating the image as a two dimensional signal and applying standard signal processing techniques to it. Image processing generally refers to digital image processing, but optical and analog image processing is also possible.

Audio signal processing is similar to audio processing, signals are first investigated and then processed digitally. It includes signals such as audio signals, image signals, ECG signals and control system signals. Audio signal processing is a combination of audio processing and signal processing. Audio processing is just a study of audio, images and other signals, and these signals are processed in digital form.

First, it was important to explain the difference between digital image processing and digital image analysis. Image processing can be thought of as transforming images into images. That is, a modified (highlighted) image is obtained from the beginning of the image. Digital image analysis, on the other hand, converts the image to something different from that image. In other words, it generates information that describes explanations and decisions. Digital image processing has three objectives; to improve the look of the image to the human observer, to extract quantitative information invisible to the eyes from the image, and to extract the image with luminance or geometric terms To calibrate. Image processing is both art and science. This is an interdisciplinary field that includes elements of photography, computer technology, optics, electronics, mathematics.

The earliest application of image processing to digital images dates back to the 1920's when telegraphy was needed to improve the quality of images transmitted over long distances. In the 1960's, image processing became to analyze and manipulate digital images, especially to improve its quality, when digital computers became powerful enough to execute important data. After the invention of computed tomography (CAT) by Sir Godfrey N. Hounsfield and Professor Allan M. Cormack (also known as computed tomography (CT)), the application of digital image processing began with biomedical science . Since the 1980's, the application of digital image processing technology began in various fields such as image enhancement / recovery, artistic effect, medical visualization, industrial inspection, law enforcement agency, human machine interface.
