Title: 2-d transform for image and video coding
Inventor: SRINIVASAN SRIDHAR
IPC: H04N19/60
Filed: 2003-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a computationally efficient transform implementation such as for use in image and video coding.  <P>SOLUTION: The transform implementation of this invention provides a set of one and two-dimensional transforms that is constructed subject to certain range limited constraints. The constraints can include that the transform has a scaled integer implementation, provides perfect or near perfect reconstruction, has a DCT-like basis function, is limited to a coefficient within a range represented in n-bits (e.g. n is 16 bits), and provides a sufficient headroom for overflow of the range. A set of transforms is constructed with this procedure having an implementation within an n-nit integer range for efficient computation using integer matrix multiplication operations.  <P>COPYRIGHT: (C)2004,JPO
