A system for the recognition of geological lineaments in remotely sensed imagery
Lineament maps are an important intermediate step in the production of geological interpretations from remotely sensed images. A system that reduces the bias and performs the most menial stages of lineament analysis allows interpreters to spend more time on tasks requiring thought and judgement. The system uses standard edge- and line-detection techniques within a structure based on a model of the human visual system. Features are recognized using a paradigm of progressive refinement of an image description within information channels an azimuth and spatial frequency. The system produces accurate and visually appealing lineament maps for practical images.
