Transition detection

With the enhancement of the editing techniques, the set of available transitions has spread and grown. Besides, anybody can build its own transitions.
Among the most transitions used, let us quote the cuts, the dissolves, the page turns, etc.

The transition diversity increases even more than the detection techniques improve. We have nevertheless built two detection techniques, which are efficient respectively in the case of simple transitions such as cuts and in the case of dissolves. The simplicity and rapidity of the techniques have been considered as the first main qualities to obtain. If the transition detection is essential for the following of the indexing process, it is in effect nevertheless only a first step, a pre-treatment which should be achieved rapidly.
