The Hough Transform Algorithm for Sea Ice Lead Analysis: An Evaluation

Abstract

An algorithm for sea ice lead analysis using a Hough transform technique has been developed at the Naval Research Laboratory (NRL) Remote Sensing Applications Branch and is currently in use at NRL and the Navy/National Oceanic and Atmospheric Administration (NOAA) Joint Ice Center (JIC). The algorithm resides on a Sun microcomputer system as part of a larger image processing package (the NRL Satellite Image Processing System or NSIPS) developed at NRL. Currently, the algorithm functions on Advanced Very High Resolution Radiometer (AVHRR) and Operational Line Scan imagery. Algorithm performance was evaluated by comparing resulting from the Hough transform technique to those obtained through manual analysis for a set of five AVHRR infrared images. The algorithm operated well, but there is still room for improvement. Details of the evaluation and recommendations for improvement are contained in this report.
