摘要

A method for determining the amplitude of an infrared object may include receiving an infrared image of the object from a sensor, and expressing the objects infrared amplitude as a function of its position coordinates. The sum of the squared residuals of the objects true infrared response and a model of the objects infrared response may be minimized to determine the centroid of the infrared image. The objects infrared amplitude may then determined based on the centroid location.
