Autores: De Pontual, Helene.
Existing methods to assess the biomass of reared oyster's stocks are ail based on aerial photographs and field data.  In this study, we propose an automatic processing of the digitized aerial photographs making use of advanced vision tools such as mathematical morphology.  The implemented a1gorithms are described. They give enough convincing results to suggest further developments.  However, this method requires the use of digital images. To this respect, a part of this paper deals with data acquisition problems. We particularly study the feasibility of using airborne video recording system. Such device should give a quite accurate information, easier to process than the classical aerial photographs.
