Video Processing Projects using Matlab

In electronics engineering, video processing is a particular case of signal processing, in particular image processing, which often employs video filters and where the input and output signals are video files or video streams.

Nvidia's High-Definition Digital Processing (HDVP) is a HDTV accelerator on the Geforce 2 GTS. It has a downscalar that supports 1080i and 720p to sdtv resolution. In combination with a tuner chip it creates an accelerated hdtv viewing system that supports time-shifted recording. The Geforce 2 GTS also includes second generation motion compensation, improved from the motion compensation on the Geforce 256. It does not seem to include IDCT acceleration. The HDVP also includes de-interlace acceleration including bob, weave, temporal filter, and advanced de-interlacing. Finally, HDVP supports subpicture compositing, and color enhancements including brightness, hue, contrast, and saturation.[1] nVidia's HDVP would endure through the GeForce 4 Series in the Geforce 4 Ti NV25

Video post-processing is the process of changing the perceived quality of a video on playback (done after the decoding process). Image scaling routines such as linear interpolation, bilinear interpolation, or cubic interpolation can for example be performed when increasing the size of images; this involves either subsampling (reducing or shrinking an image) or zooming (enlarging an image). This helps reduce or hide image artifacts and flaws in the original film material. It is important to understand that post-processing always involves a trade-off between speed, smoothness and sharpness.
