Abstract

In-scene glint greatly affect the usability of maritime imagery and several glint removal algorithms have been developed that work well in some situations. However, glint removal algorithms produce several unique artifacts when applied to very high resolution systems, particularly those with temporally offset bands. The optimal solution to avoid these artifacts is to avoid imaging in areas of high glint. The glint avoidance tool (GAT) was developed to avoid glint conditions and provide a mea- sure of parameter detectability. This work recreates the glint avoidance tool using Hydrolight, as a validation of a fast GAT using an in-water radiative transfer model which neglects in-water scattering. Because avoiding glint is not always possible, this research concentrates on the impact of glint and residual artifacts using RIT's Digital Imaging and Remote Sensing Image Generation (DIRSIG) dynamic wave model and Hydrolight back-end to create accurate case 1 synthetic imagery. The synthetic imagery was used to analyze the impact of glint on automated anomaly detection, glint removal, and development of a new glint compensation technique for sensors with temporally offset bands.
