Paper Abstract

We present a new method for automatic thresholding of thermal images when the target is a landing aircraft. The raw thermal image is subjected to clip-low operations based on a sequence of threshold pairs. Each threshold pair is derived from the median and upper hinge (in Tukey's sense) of the sub-sampled raw image. The inter-centroid distance for each resulting image pair in the sequence along with the corresponding sample population are used to select the desired threshold. Experimental results on real FLIR imagery are presented.
