The Ice Processing System is a digital image processing function that performs sea-ice lead statistics analysis functions and ice-motion estimations. The menu-driven process permits the user to utilize Advanced Very High Resolution Radiometer and/ or Operational Line Scan infrared or visible satellite imagery. The lead analysis software utilizes a Hough transform technique to determine lead orientation statistics. The function also provides/ displays lead size, lead orientation, and lead spacing information in various forms to the user. Ice-motion vectors are obtained automatically from image pairs using a cross-correlation technique. The resultant motion vectors are then displayed over a screen image. Together, these techniques provide analysts with near-real-time indications of sea-ice conditions over regions of interest. Sea ice forecasting, Sea ice models, Sea ice analysis.
