Abstract :
This work aims at automatically identify and extract the region covered by the upwelling waters in the costal ocean of Morocco using the well-known region-growing segmentation algorithm. The later consists in coarse segmentation of upwelling area which characterized by cold and usually nutrient-rich water near the coast. The proposed approach has been validated by an oceanographer over a database of 30 Sea Surface Temperature (SST) satellite images of the year 2007 obtained from Advanced Very High Resolution Radiometer (AVHRR) sensor onboard NOAA-18 satellite serie. The results show a robustness and effectiveness to detect and reproduce the shape of upwelling area.
