Abstract
A method of identifying a rip current that includes receiving an image comprising a body of water, and identifying, in the image an estimated location of a rip current associated with the body of water, wherein the identification comprises a plurality of displayed vertices based on least one of a rip length or a rip width. The method may include digitizing the estimated location of the rip current, the estimated location having highest, lower, and no confidence boundaries. The method may include generating, based on the digitized estimated location, a set of fuzzy-set scheme labels for one or more pixels in the image based on a respective confidence boundary, where the fuzzy-set scheme labels are based on a pixel interpolation associated with the lower confidence boundary, and generating, based on the generated fuzzy-set scheme labels, a refined digitizing of the estimated location of the rip current.
