Abstract: An exemplary system includes a memory that stores instructions and a processor communicatively coupled to the memory. The processor is configured to execute the instructions to access a thermal image captured by a thermal imaging device, the thermal image including a plurality of pixels, convert the thermal image to a heatmap image, generate a foreground image by separating a background represented in the heatmap image from a foreground represented in the heatmap image, identify, in the foreground image, at least one hotspot representing a heat source located at the user premises, determine a contour shape of the at least one hotspot, and determine, based on the contour shape of the at least one hotspot, whether the at least one hotspot represented in the foreground image represents a target heat source located at the user premises.

Abstract: A system described herein may generate visual representations of physical locations, such as floors of office buildings, outdoor areas, or other types of places. The visual representations may be based on a node map, which may be generated based on data received from user devices and/or by owners or proprietors of business or other types of locations. The node map, for a given place, may indicate features of the place, such as architectural features (e.g., doors, walls, or rooms), visible features (e.g., wall hangings, signs, or other landmarks), Radio Frequency (“RF”) footprint features, or other features. The node map may indicate the likelihood of a given user device moving from one node to another node, and these likelihoods may be used to generate navigation instructions.
