Abstract
Image compression addresses the problem of reducing the amount of data required to represent a digital
image called the redundant data.
The underlying basis of the reduction process is the removal of redundant
data.
The redundancy used here is pschychovisual redundancy.
3D-DCT video compression algorithm takes
a full-motion digital video stream and divides it into groups of 8 frames.
Each group of 8 frames is
considered as a three-dimensional image, which includes 2 spatial components and one temporal
component.
