2. Image geometry correction - Wikipedia

   en.wikipedia.org/wiki/Image_geometry_correction

   Image Geometry Correction onto regular surfaces (such as spheres and cylinders) is the next level of complexity. Both these regular shapes are encountered frequently in Professional Audio Video (Pro AV) situations, in the form of domed or curved wall theatres. Other commonly encountered regular-shaped surfaces are subway walls and pillars.

3. Corner detection - Wikipedia

   en.wikipedia.org/wiki/Corner_detection

   Corner detection is an approach used within computer vision systems to extract certain kinds of features and infer the contents of an image. Corner detection is frequently used in motion detection, image registration, video tracking, image mosaicing, panorama stitching, 3D reconstruction and object recognition.

4. Fillet (mechanics) - Wikipedia

   en.wikipedia.org/wiki/Fillet_(mechanics)

   An interior or exterior corner, with an angle or type of bevel, is called a "chamfer". Fillet geometry, when on an interior corner is a line of concave function, whereas a fillet on an exterior corner is a line of convex function (in these cases, fillets are typically referred to as rounds

5. Harris corner detector - Wikipedia

   en.wikipedia.org/wiki/Harris_corner_detector

   The Harris corner detector is a corner detection operator that is commonly used in computer vision algorithms to extract corners and infer features of an image. It was first introduced by Chris Harris and Mike Stephens in 1988 upon the improvement of Moravec's corner detector . [ 1 ]

6. Hidden-line removal - Wikipedia

   en.wikipedia.org/wiki/Hidden-line_removal

   A wire-frame image using hidden-line removal. In 3D computer graphics, solid objects are usually modeled by polyhedra. A face of a polyhedron is a planar polygon bounded by straight line segments, called edges. Curved surfaces are usually approximated by a polygon mesh.

7. Distortion (optics) - Wikipedia

   en.wikipedia.org/wiki/Distortion_(optics)

   In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
