Computer vision is the science and technology of machines that see Digital image processing is the use of computer Algorithms to perform Image processing on Digital images As a subfield of Digital signal processing An image histogram is type of Histogram which acts as a graphical representation of the tonal distribution in a Digital image. Histogram equalization is a method in Image processing of contrast adjustment using the image 's histogram. Tone mapping is a technique used in Image processing and Computer graphics to map a set of colours to another often to approximate the appearance of High dynamic Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma, is the name of a nonlinear operation used to code and decode luminance In Geometry, an affine transformation or affine map or an affinity (from the Latin affinis, "connected with" between two Vector The Hough transform (ˈhʌf rhymes with tough) is a Feature extraction technique used in Image analysis, Computer vision, and Digital image In Mathematics, the Radon transform in two dimensions named after the Austrian mathmematician Johann Radon, is the Integral transform consisting of the The Hadamard transform (also known as the Walsh-Hadamard transform, Hadamard-Rademacher-Walsh transform, Walsh transform, or Walsh-Fourier transform A filter bank is an array of band-pass filters that separates the input signal into several components each one carrying a single Frequency Subband A Gabor filter is a Linear filter whose Impulse response is defined by a Harmonic function multiplied by a Gaussian function JPEG 2000 is a Wavelet -based Image compression standard It was created by the Joint Photographic Experts Group committee in the year 2000 with the intention An adaptive filter is a filter that self-adjusts its Transfer function according to an optimizing algorithm In the study of the perception of Color, one of the first mathematically defined Color spaces was the CIE 1931 XYZ color space (also known as CIE 1931 color space A Color model is an abstract mathematical model describing the way Colors can be represented as Tuples of numbers typically as three or four values or color components In digital imaging systems color management is the controlled conversion between the Color representations of various devices such as Image scanners Digital In Color management, an ICC profile is a set of data that characterizes a color input or output device or a Color space, according to standards promulgated by the The method of least squares is used to solve Overdetermined systems Least squares is often applied in statistical contexts particularly Regression analysis. In Computer science, geometric hashing is a method for efficiently finding two-dimensional objects represented by discrete points that have undergone an Affine transformation Particle filters, also known as sequential Monte Carlo methods (SMC are sophisticated model Estimation techniques based on Simulation. RANSAC is an abbreviation for "RANdom SAmple Consensus" Given a set of images depicting a number of 3D points from different viewpoints, bundle adjustment can be defined as the problem of simultaneously refining the 3D coordinates In the area of Computer vision, ' blob detection' refers to visual modules that are aimed at detecting points and/or regions in the image that are either brighter or darker An Active Appearance Model (AAM is a Computer vision algorithm for matching a Statistical model of object shape and appearance to a new image Projective geometry is a non- metrical form of Geometry, notable for its principle of duality. The pinhole camera model describes the mathematical relationship between the coordinates of a 3D point and its Projection onto the image plane of an ideal Pinhole Epipolar geometry refers to the geometry of stereo vision. When two cameras view a 3D scene from two distinct positions there are a number of geometric relations between the In Computer vision, the fundamental matrix \mathbf{F} is a 3 \times 3 matrix of rank 2 which relates corresponding points in stereo In Computer vision, the trifocal tensor can be considered as the generalization of the fundamental matrix in three views Edge detection is a terminology in Image processing and Computer vision, particularly in the areas of feature detection and Feature extraction The Canny Edge detection operator was developed by John F Canny in 1986 and uses a multi-stage Algorithm to detect a wide range of edges in images Active Contour, also called Snakes, is a framework for delineating an object outline from a possibly noisy 2D Image. The level set method (sometimes abbreviated as LSM) is a numerical technique for tracking interfaces and Shapes The advantage of the level set method is In Signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them Scale-space theory is a framework for multi-scale signal representation developed by the Computer vision, Image processing and Scale-invariant feature transform (or SIFT) is an algorithm in Computer vision to detect and describe local features in images A Markov network, or Markov random field, is a model of the (full Joint probability distribution of a set \mathcal{X} of Random variables In Computer vision the motion field is an ideal representation of 3D motion as it is projected onto a camera image In Video compression, a motion vector is the key element in the Motion estimation process Optical flow or optic flow is the pattern of apparent motion of objects surfaces and edges in a visual scene caused by the relative motion between an observer In Computer vision, segmentation refers to the process of partitioning a Digital image into multiple Regions ( sets of Pixels. The medial axis is a method for representing the Shape of objects by finding the Topological skeleton, a set of curves which roughly run along the middle of an object This is a list of Computer graphics and Descriptive geometry topics, by article name Virtual Design and Construction (VDC is the use of integrated multi-disciplinary performance models of Design - Construction projects including the Product (i
