Difficulties and high computational costs in the model establishmen and parameter estimation seriously de-graded the efficiency of the underwater object detection system. making them too cumbersome to the practical work. A noval light intensity. spectrum and polarization feature fusion method was proposed. https://www.markbroyard.com/deal-time-gtech-airram-mk2-k9-roller-roll-brush-bar-filter-vacuum-cleaner-hot-on-sale-best-find/
