Bicubic Interpolation
Bicubic interpolation is an image processing method. If an image is enlarged beyond its
original size, not only are the four neighboring pixels analyzed to calculate the new resulting
pixel, but other nearby pixels are analyzed as well. This way, the new pixel is interpolated
based on eight neighboring pixels.
Bilinear Interpolation
Bilinear interpolation refers to an image processing method. If a picture is enlarged beyond
its original size, the resulting new image pixels are calculated based on the average between
the four neighboring pixels. The more a picture is enlarged with this method, the less sharp it
becomes.
Bit rate
Bit rate refers to the amount of data (binary digits) that is transmitted within a time unit
(generally 1 second), i.e. in bits/s. The higher the bit rate, the better the image quality.
Deinterlace
The deinterlacing process converts interlaced video files into complete frames (progressive),
since computer displays and modern televisions do not work with the interlaced system
anymore, but rather with complete frames.
GOP
A Group of Pictures refers to a group of consecutive individual pictures in the picture flow of
a video file. Each movie or video flow consists of consecutive GOP's. The viewable individual
pictures are generated from them.
Lanczos interpolation
Lanczos interpolation refers to an image enlargement method. The method was developed
according to an algorithm created by Cornelius Lanczos. This interpolation method provides
high quality and good sharpness levels. However, the actual visual resolution of the images
is not increased.
Superresolution
The interpolation with superresolution algorithms permits an increase of resolution in picture
and video material. Thus, for instance, old DVDs can be converted to HD material. The
increase in resolution is the result, among others of information on previous and following
pictures.
