  • receiving, by a processor, the image;

    calculating, by the processor, a score for each one of a plurality of locations in the image;

    performing, by the processor, a box plot of the score of the each one of the plurality of locations of the image;

    identifying, by the processor, an outlier score that falls outside of the box plot;

    determining, by the processor, that a distance ratio of the outlier score is less than a predefined distance ratio, wherein the distance ratio is a ratio that is based upon a comparison of a first distance of a second highest score and a second distance of the outlier score; and

    detecting, by the processor, the object in a location of the plurality of locations of the image corresponding to the outlier score.
