Abstract
The invention relates to a method and device for generating a large static image M(n), such as a sprite or a mosaic, from a video sequence including successive video objects. This method comprises a first step for estimating motion parameters related to the current video object V (n) of the sequence with respect to the previously generated static image M(n−1), a second step for warping this video object on the basis of the estimated motion parameters, and a third step for blending the warped video object WV (n) thus obtained with the previously generated static image M(n−1). According to the invention, an additional step for computing, for each picture element of the current video object, a weighting coefficient w [x,y] correlated to the error between the warped video object and the static image M(n−1) is provided, and the blending formula now takes into account said weighting coefficients.
