Abstract
The present invention provides techniques for detecting foreign objects in a region of interest in maritime environments. Image data indicative of a sequence of successively acquired images of the region of interest, is analyzed to determine candidate points of interest, and data indicative of said points is processed to identify candidate points that are adjacently accumulated in different locations in images data. Grouping data may be then generated based on the identified accumulations of candidate points indicative of a group of said candidate points. The grouping data is processed to identify spatio-temporal correlation between the points in the group and determine a corresponding track function, thereby enabling detection of a presence of a foreign object in the image data.
