The use of edge-enhancing smoothing pre-filters to aid in the detection of oceanic features
José M. Ortiz, Miguel Vélez-Reyes · 2005
Sea Surface Temperature (SST) images obtained by satellites, such as AVHRR, are used to detect turbulent oceanic pattern flows. Pre-processing techniques (filters) are used to remove possible noise contamination from the obtained images and improve oceanic feature detection. In this paper, we present how image pre-processing techniques based on the use of edge-enhancing smoothing nonlinear filters improve the detection of oceanic features by enhancing diffuse edges and removing scattered clouds present in SST imagery.
