Open the CIPO recordAbstract From the Canadian patent
A mosaic image is formed from a database of source images. More particularly, the source images are analyzed selected and organized to produce the mosaic image. A target image is divided into tile regions, each of which is compared with individual source image portions to determine the best available matching source image by computing red green and, blue channel root-mean square error. The mosaic image is formed by positioning the respective best-matching source images at the respective tile regions.

Why it's free to use
- Filed December 31, 1997 and granted October 9, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 31, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 31, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
