An example of a typical computer vision computation pipeline for face recognition using k-NN including feature extraction and dimension reduction pre-processing steps (usually implemented with OpenCV): Haar face detection; Mean-shift tracking analysis; PCA or Fisher LDA projection into feature space, followed by k-NN classification
Graphics represented as a rectangular grid of pixels. Rasterization Converting vector graphics to raster graphics. This terms also denotes a common method of rendering 3D models in real time. Ray casting Rendering by casting non-recursive rays from the camera into the scene. 2D ray casting is a 2.5D rendering method. Ray marching
The set of images in the MNIST database was created in 1994. Previously, NIST released two datasets: Special Database 1 (NIST Test Data I, or SD-1); and Special Database 3 (or SD-2).
Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.
The fields of graphics, games, and machine learning are the main adopters of this software design with the majority of tools using node graph architecture. [citation needed] To this day, there is some debate as to the benefits of visual programming and node graph architecture. Advocates highlight how the abstraction that node graphs provide ...
In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards.
The Warnock algorithm is a hidden surface algorithm invented by John Warnock that is typically used in the field of computer graphics. [1] It solves the problem of rendering a complicated image by recursive subdivision of a scene until areas are obtained that are trivial to compute.
In computer graphics, back-face culling determines whether a polygon that is part of a solid needs to be drawn. [ 1 ] [ 2 ] [ 3 ] Polygons that face away from the viewer do not need to be drawn, as they will be obscured by other polygons facing the viewer.
