Perspective control. Perspective control is a procedure for composing or editing photographs to better conform with the commonly accepted distortions in constructed perspective. The control would: make all lines that are vertical in reality vertical in the image. This includes columns, vertical edges of walls and lampposts. This is a commonly ...
Celemony Software GmbH is a German musical software company that specializes in digital audio pitch correction software. It produces Melodyne, a popular audio pitch modification tool similar to Auto-Tune , although the program itself is manual tuning software.
Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape. [1] Image geometry correction compensates for the distortion created by off-axis projector or screen placement or non-flat screen surface ...
A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror. Figure 1 shows the construction of such a compressor. Although the dispersion of the prism material causes ...
Atmospheric correction is the process of removing the scattering and absorption effects of the atmosphere on the reflectance values of images taken by satellite or airborne sensors. [1] [2] Atmospheric effects in optical remote sensing are significant and complex, dramatically altering the spectral nature of the radiation reaching the remote ...
Prism graphs are examples of generalized Petersen graphs, with parameters GP ( n ,1). They may also be constructed as the Cartesian product of a cycle graph with a single edge. [1] As with many vertex-transitive graphs, the prism graphs may also be constructed as Cayley graphs. The order- n dihedral group is the group of symmetries of a regular ...
PRISM is a code name for a program under which the United States National Security Agency (NSA) collects internet communications from various U.S. internet companies. [1] [2] [3] The program is also known by the SIGAD US-984XN. [4] [5] PRISM collects stored internet communications based on demands made to internet companies such as Google LLC ...
Pitch correction. Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano ). Pitch correction devices do this without affecting other aspects of its sound.
