If the images to be rectified are taken from camera pairs without geometric distortion, this calculation can easily be made with a linear transformation.X & Y rotation puts the images on the same plane, scaling makes the image frames be the same size and Z rotation & skew adjustments make the image pixel rows directly line up [citation needed].
Elfster was founded by software engineer Peter Imburg in 2004 after hearing about the difficulty his wife and sister had when trying to organize a Secret Santa for their family. [4] [5] In November 2011, the website reached 2 million members. In Christmas of the same year, the Elfster Facebook App was launched for mobile device users. The app ...
Virtual cinematography is the set of cinematographic techniques performed in a computer graphics environment. It includes a wide variety of subjects like photographing real objects, often with stereo or multi-camera setup, for the purpose of recreating them as three-dimensional objects and algorithms for the automated creation of real and simulated camera angles.
In the field of computer vision, any two images of the same planar surface in space are related by a homography (assuming a pinhole camera model). This has many practical applications, such as image rectification , image registration , or camera motion—rotation and translation—between two images.
DeepArt or DeepArt.io was a website that allowed users to create artistic images by using an algorithm to redraw one image using the stylistic elements of another ...
A view frustum The appearance of an object in a pyramid of vision When creating a parallel projection, the viewing frustum is shaped like a box as opposed to a pyramid.. In 3D computer graphics, a viewing frustum [1] or view frustum [2] is the region of space in the modeled world that may appear on the screen; it is the field of view of a perspective virtual camera system.
Calligraphic projection is a system for displaying or projecting an image composed of a beam of light or electrons directly tracing the image, as opposed to sweeping in raster order over the entire display surface, as in a standard pixel-based display.
Adaptive tile refresh is a computer graphics technique for side-scrolling video games. It was most famously used by id Software 's John Carmack in games such as Commander Keen to compensate for the poor graphics performance of PCs in the early 1990s.
