Open the CIPO recordAbstract From the Canadian patent
A method is described for estimating the motion for image sequences carrying out a decimation of the function used for the extraction of the characteristic parameters of an image block. The method is iterated by decreasing the function decimation and carrying out the block-matching on a set of the best matchings of the preceding steps. The method does not require the recalculation of the parameters on the referenceimage for each block to be matched; moreover in the extraction of the, characteristic parameters of a block the use of the Integral Projections is notmandatory but one of the possible variants only (Fig. 1).

Why it's free to use
- Filed March 10, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
