A Rough Transform Technique for Extracting Lead Features from Sea Ice Imagery

Infrared imagery from polar-orbiting satellites provides a synoptic and long-term view of lead patterns in Artic pack ice: The large quantity of satellite data in image form suggests the use of automated methods for compiling lead statistics from imagery. A Hough transform technique for the semi-aut...

Description
Summary:Infrared imagery from polar-orbiting satellites provides a synoptic and long-term view of lead patterns in Artic pack ice: The large quantity of satellite data in image form suggests the use of automated methods for compiling lead statistics from imagery. A Hough transform technique for the semi-automated extraction of lead orientation and spacing is described and first results are presented.
