ANALYSIS OF THE EFFICIENCY OF THE ADAPTIVE CANNY METHOD FOR THE DETECTION OF ICEBERGS AT OPEN SEA
The detection of icebergs in the open sea, as well as its evolution in displacement and shrinking, is vital for navigation, the study of the evolution of Polar regions, and the Earth climate change, among others. In order to carry out these studies, it is necessary to delimit accurately the icebergs...
