Abstract :
This paper describes an original approach for structuring video documents into scenes by grouping video shots. The method is based on the construction of 1D mosaics. 1D mosaics are built based on X-ray projections of color video frames representing integration along vertical and horizontal axes. The mosaicing is realized by motion compensation in a 1D domain. Grouping of shots in a scene is done by local and global matching of mosaics, based on piecewise linear approximation and hierarchical clustering. The results obtained on feature documentaries are promising.
