Interface for digitization and detection of rip currents within optical imagery by way of a fuzzy set

A method of identifying a rip current, comprising:

• receiving, by a computing device, an image comprising a body of water;
• identifying, by the computing device, 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;
• digitizing, by the computing device and based on the displayed vertices, the estimated location of the rip current, the estimated location comprising a highest confidence boundary, a lower confidence boundary, and a no confidence boundary;
• generating, by the computing device and 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, wherein the fuzzy-set scheme labels are based on a pixel interpolation associated with the lower confidence boundary;
• and
• generating, by the computing device and based on the generated fuzzy-set scheme labels, a refined digitizing of the estimated location of the rip current associated with the body of water,
• wherein identifying the estimated location comprises generating a cross-segment of a segment of the rip length and a segment of the rip width, wherein the cross-segment comprises four vertices associated with the rip length and the rip width and is used to digitize the rip current.
