A method and apparatus for efficiently encoding images using a set of nonorthogonal basis functions, thereby allowing reduction of file size shorter , transmission time, and improved accuracy. The non-orthogonal basis functions include homogenous color basis functions luminance-encoding basis functions , that have luminance edges and chromatic basis functions that exhibit color opponency. Some of the basis functions are non-orthogonal with respect to each other. Using these basis functions, a source vector is calculated to provide a number of coefficients, each coefficient associated with one basis function. The source vector is compressed by selecting a subset of the calculated …

Why it's free to use
- Filed April 30, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 30, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 30, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
