Abstract

This paper introduces a model based morphology technique for detecting linear segments in Landsat TM imagery. Linear segment detection has been identified as the initial step in many automated processes -- multiple image registration using linear features, lines of communication (LOC) detection, and target detection algorithms. Even though there have been many research studies aimed at the detection of linear segments in single band imagery, little research has been done on multispectral data which considers all the bands simultaneously. The fundamental idea behind this paper is to apply normal gray level image operations to multispectral imagery. Simply applying a single band edge detection algorithm to each band separately ignores the radiometric response of the edge detector. Applying morphological based operations to each band and accounting for the radiometric response of the target (i.e., LOC) pixels, one may develop a measure for the radiometric fit for each band and combine the individual band responses into a single useful output. Application of the model-based morphological filter designed in accordance with the radiometric responses of the linear segments and fusion of the results from all the bands improves linear segment detection.
