Wavelet transform. An example of the 2D discrete wavelet transform that is used in JPEG2000. In mathematics, a wavelet series is a representation of a square-integrable ( real - or complex -valued) function by a certain orthonormal series generated by a wavelet. This article provides a formal, mathematical definition of an orthonormal wavelet ...
Gamma correction is a type of power law function whose exponent is the Greek letter gamma ( γ ). It should not be confused with the mathematical Gamma function. The lower case gamma, γ, is a parameter of the former; the upper case letter, Γ, is the name of (and symbol used for) the latter (as in Γ ( x )).
Alpha compositing. This color spectrum image's alpha channel falls off to zero at its base, where it is blended with the background color. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]
Some containers only support a restricted set of video formats: DMF only supports MPEG-4 Visual ASP with DivX profiles. EVO only supports MPEG-4 AVC, MPEG-1 Video, MPEG-2 Video and VC-1. F4V only supports MPEG-4 AVC, MPEG-4 Visual and H.263. FLV only supports MPEG-4 Visual, VP6, Sorenson Spark and Screen Video.
A Multimedia database ( MMDB) is a collection of related for multimedia data. [1] The multimedia data include one or more primary media data types such as text, images, graphic objects (including drawings, sketches and illustrations) animation sequences, audio and video . A Multimedia Database Management System ( MMDBMS) is a framework that ...
Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. [citation needed] The resulting image is referred to as a rendering. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.
Linear video editing. Linear video editing is a video editing post-production process of selecting, arranging, and modifying images and sound in a predetermined, ordered sequence. [1] Regardless of whether it was captured by a video camera, [2] tapeless camcorder, or recorded in a television studio on a video tape recorder (VTR) the content ...
The standard describes the format of the encoded data and how the data is decoded, but it does not specify algorithms for encoding video – that is left open as a matter for encoder designers to select for themselves, and a wide variety of encoding schemes have been developed.
