Abstract
The invention relates to a document-processing system, which includes a device suitable for supplying consecutive recorded images as well as a background surface, comprising a step of storing a standard background surface image. The next step consists of detecting the presence of a document moving across a series of recorded images relative to the standard background surface image. The following step consists of monitoring the movement of the document within the series of images. The end of the movement of the document is then detected and the standard background surface image is updated. The movement of the document is monitored by determining document-extraction masks respectively for the recorded images, the extraction mask of a recorded image being obtained according to an entropy card of the recorded image relative to said standard background surface image.
