The method comprises the following steps:
- detection of non-static pixels (2) in a picture, with respect to a preceding picture,
- calculation of the number of non-static pixels (3) in the picture,
- calculation of the variation (5), in absolute value, of the number of non-static pixels for the picture, corresponding to the difference between the number of non-static pixels of the picture and that of the preceding picture,
- detection of a peak in the variation (7), the picture relative to the variation leading to the peak then being the first picture of the new scene. The applications relate to video coding, for example video stream switches. |
