Application of Image Processing Techniques to Marine Fisheries

The problem of subdividing an ocean area into coherent subregions is investigated. The subdivision is based on the image processing technique of region segmentation. The region segmentation applied is the Global-Local Edge Coincidence algorithm (GLEC). GLEC requires the application of several image processing operations including clustering, gradient analysis, region labelling, and others. The data bases selected for this analysis consist of the Nimbus-7 Satellite CZCS sensor derived phytoplankton concentration and temperature images. The interpretation of the resulting ocean area subdivision is also discussed.
