A method and system for receiving, processing, responding and managing firefighter request calls is described. The vessel is charged with a batch of an aqueous solution of H2S scavenging treatment liquid. The correction coefficients are progressively updated and improved by means of a dynamic correction process. The electrode tab is electrically connected to the power generating member and protruding outwardly from the cell main body. This segmentation uses a similarity criterion involving, for sub-entities of each shot, the level of homogeneity of these sub-entities on the motion parameters of the camera used to acquire the original images and generate the bitstream constituting the processed sequence.
