Assignee: UNIVERSITY OF CONNECTICUT
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A system to generate a flood inundation map, the system comprising:
a flood trigger system configured to identify a flood occurring zone having one or more bodies of water;
a SAR data query system to identify relevant satellite images for the flood occurring zones; and
a kernel algorithm system including an electronic processor configured to
receive the data from the flood trigger system,
receive the satellite images from the SAR data query system,
generate a binary classification of water and non-water at pixel level of the satellite images,
morphologically process the satellite images to reduce over-detection of the bodies of water and to reduce under-detection of the bodies of water,
apply a multi-threshold compensation to reduce speckle noise in the bodies of water,
apply machine learning-based correction for speckle, and
generate a flood inundation map.
