An image is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving...

called an image point, is a point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically...

In mathematics, for a function f : X → Y {\displaystyle f:X\to Y} , the image of an input value x {\displaystyle x} is the single output value produced...

The point spread function (PSF) describes the response of a focused optical imaging system to a point source or point object. A more general term for...

A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of mutually parallel lines...

at each image point is a 2D vector with the components given by the derivatives in the horizontal and vertical directions. At each image point, the gradient...

the mirror/lens than the focal point, and this real image is inverted. As the object approaches the focal point the image approaches infinity, and when...

In optics, an erect image is one that appears right-side up. An image is formed when rays from a point on the original object meet again after passing...

part of an image, and features are used as a starting point for many computer vision algorithms. Since features are used as the starting point and main...

In digital image processing and computer vision, image segmentation is the process of partitioning a digital image into multiple image segments, also...

spread out over some region of space rather than focused to a point. Aberrations cause the image formed by a lens to be blurred or distorted, with the nature...

field of view of an image for use as a point of reference or a measure. It may be either something placed into or on the imaging subject, or a mark or...

The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics. The name...

ImageJ is a Java-based image processing program developed at the National Institutes of Health and the Laboratory for Optical and Computational Instrumentation...

monocular image depth estimation using deep learning. For 2D point set registration used in image processing and feature-based image registration, a point set...

new image[1, 1] = 1 9 {\displaystyle {\tfrac {1}{9}}} * (image[0,0]+image[0,1]+image[0,2]+image[1,0]+image[1,1]+image[1,2]+image[2,0]+image[2,1]+image[2...

brightness of a given color at any specific point. Typically, the pixels are stored in computer memory as a raster image or raster map, a two-dimensional array...

at the scan point. The size of the striking ray is tiny compared to the size of the target, allowing 480–486 horizontal scan lines per image in the NTSC...

triangulation refers to the process of determining a point in 3D space given its projections onto two, or more, images. In order to solve this problem it is necessary...

In optics, the image of an object is defined as the collection of focus points of light rays coming from the object. A real image is the collection of...

two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect...

Image restoration may refer to: Conservation and restoration of photographs Digital photograph restoration Image restoration by artificial intelligence...

Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means...

high-resolution image. Commonly performed through the use of computer software, most approaches to image stitching require nearly exact overlaps between images and...

points in a scene from a specific point, normally associated with some type of sensor device. The resulting range image has pixel values that correspond...

relationship between the coordinates of a point in three-dimensional space and its projection onto the image plane of an ideal pinhole camera, where the...

image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost. The 3D point corresponding to a specific image point is...
