Formatted abstract
Specular reflection of solar radiation on non‐flat water surfaces is a serious confounding factor for benthic remote sensing in shallow‐water environments. This problem was recently overcome by Hochberg et al., who provided an effective method for the removal of ‘sun glint’ from remotely sensed images by utilization of the brightness in a near‐infrared (NIR) band. Application of the technique was shown to give an increase in the accuracy of benthic habitat classification. However, as presented, the method is sensitive to outlier pixels, requires a time‐consuming masking of land and cloud, and is not formulated in a manner leading to ease of implementation. We present a revised version of the method, which is more robust, does not require masking and can be implemented very simply. The practical approach described here will hopefully expedite the routine adoption of this effective and simple technique throughout the aquatic remote sensing community.
