Abstract: A method of detecting concealed objects using a thermal imager includes obtaining an output comprising a plurality of pixels representing a person, analyzing each pixel matching a contour of the person and excluding any pixel within a blob bounding box of the person, and determining whether a pixel address is represented in a pixel map. In addition, the method includes comparing a value of each remaining pixel to an allowable minimum threshold value representing a lower pre-defined body temperature, and comparing the value of each remaining pixel greater than or equal to the allowable minimum threshold value to an upper allowable threshold value representing an upper pre-defined body temperature. The method also includes excluding any of the remaining pixels within a range between the lower and upper pre-defined body temperatures to define final set of pixels and calculating a pixel difference to indicate a severity of the difference.

Abstract: A method and system for detecting concealed objects using a handheld thermal imager is disclosed. In a particular embodiment, the method includes capturing thermal sensor data from the handheld thermal imager, transmitting the thermal sensor data to a processor, and formatting the sensor data using the processor. The method also includes identifying a pre-determined relative difference between a temperature of a subject and a background scene and isolating the subject of interest from the background scene in the thermal sensor data using the processor. In addition, the method includes detecting a deviation in the temperature within a discrete area to suggest a size and location of the concealed object on the subject and filtering the thermal sensor data to generate a visual image displaying the concealed object on the subject of interest.
