Abstract:The infrared thermopile array sensor detects the object at motion based on the infrared radiation radiated by the human body. The infrared radiation radiated is related to the human body temperature. Temperature difference exist between the human body and room temperature. Temperature values are obtained as the person approaches the field of view of a sensor. In this paper a mechanism is developed to track the moving object based on their centroid values. From the each temperature frame the foreground region is extracted and from the obtained centroid value of each region, the object is tracked by representing the bounding box across the tracked foreground region.
