Techniques for Segmenting Infrared Cloud Cover Images

Abstract

This report investigates three techniques for segmenting cloud cover images into regions of homogeneous cloud type. Two of these techniques select thresholds based on an analysis of the edge strengths of the borders of the above-thresholds connected components (or of the coldest such component). The third technique selects thresholds based on cluster analysis of the infrared histogram, combined with a statistical feature analysis of the clusters in the image domain.
