Abstract:
A method for building in a coding environment a mosaic representing a composite of multiple images, comprising:forming a mosaic out of a first image;segmenting a second image into background regions and foreground regions by identifying changes between the second image and the mosaic; andupdating the mosaic only with the segmented background regions of the second image,the method including:identifying regions that have changed between the first and second image;segmenting background regions in the second image where associated regions in a current mosaic are unknown and where there have not been any identified changes in the associated regions of the first and second image;segmenting background regions in the second image where there have not been any identified changes between the second image and the associated regions in the current mosaic;segmenting foreground regions in the second image where there have been changes between the second image and the associated regions in the current mosaic;segmenting foreground regions in the second image where there have been identified changes between first image and second image and associated regions in the current mosaic are unknown; andsegmenting foreground regions in the second image where there have been identified regions that only exist in the second image and associated regions in the current mosaic are unknown.
