1. A method of localizing of wireless transmitters, the method comprising: retrieving, by a localization device, one or more Received Signal Strength Indicator (RSSI) values measured by one or more sensors, corresponding to a plurality of wireless transmitters distributed in a region in which the one or more sensors are located; generating, by the localization device, a plurality of clusters based on the retrieved one or more RSSI values, wherein the generation of the plurality of clusters is based on a K-means clustering algorithm; generating, by the localization device, a binary image based on the generated plurality of clusters, wherein the binary image comprises one or more white regions and one or more black regions; and localizing, by the localization device, a position of each of the plurality of wireless transmitters, based on a determination of contours of the one or more white regions present in the binary image, wherein the one or more white regions in the binary image are indicative of a region in which one of the plurality of wireless transmitters is present.
