  2. Digital image processing - Wikipedia

    en.wikipedia.org/wiki/Digital_image_processing

    Digital image processing is the use of a digital computer to process digital images through an algorithm. [ 1 ] [ 2 ] As a subcategory or field of digital signal processing , digital image processing has many advantages over analog image processing .

  3. Canny edge detector - Wikipedia

    en.wikipedia.org/wiki/Canny_edge_detector

    An edge in an image may point in a variety of directions, so the Canny algorithm uses four filters to detect horizontal, vertical and diagonal edges in the blurred image. The edge detection operator (such as Roberts , Prewitt , or Sobel ) returns a value for the first derivative in the horizontal direction (G x ) and the vertical direction (G y ).

  4. Edge detection - Wikipedia

    en.wikipedia.org/wiki/Edge_detection

    The same problem of finding discontinuities in one-dimensional signals is known as step detection and the problem of finding signal discontinuities over time is known as change detection. Edge detection is a fundamental tool in image processing, machine vision and computer vision, particularly in the areas of feature detection and feature ...

  5. Median filter - Wikipedia

    en.wikipedia.org/wiki/Median_filter

    The median filter is a non-linear digital filtering technique, often used to remove noise from an image, [1] signal, [2] and video [3]. Such noise reduction is a typical pre-processing step to improve the results of later processing (for example, edge detection on an image).

  6. Feature (computer vision) - Wikipedia

    en.wikipedia.org/wiki/Feature_(computer_vision)

    Feature detection is a low-level image processing operation. That is, it is usually performed as the first operation on an image and examines every pixel to see if there is a feature present at that pixel. If this is part of a larger algorithm, then the algorithm will typically only examine the image in the region of the features.

  7. Digital imaging - Wikipedia

    en.wikipedia.org/wiki/Digital_imaging

    In the field of technology, digital image processing has become more useful than analog image processing when considering the modern technological advancement. Image sharpen & reinstatement – Image sharpens & reinstatement is the procedure of images which is capture by the contemporary camera making them an improved picture or manipulating ...

  8. Image analysis - Wikipedia

    en.wikipedia.org/wiki/Image_analysis

    Image analysis or imagery analysis is the extraction of meaningful information from images; mainly from digital images by means of digital image processing techniques. [1] Image analysis tasks can be as simple as reading bar coded tags or as sophisticated as identifying a person from their face .

  9. Image segmentation - Wikipedia

    en.wikipedia.org/wiki/Image_segmentation

    In digital image processing and computer vision, image segmentation is the process of partitioning a digital image into multiple image segments, also known as image regions or image objects (sets of pixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to ...
