Multi-Class Weather Classification Method using Multiple Weather Features and Supervised Learning

Abstract

Traffic accidents are particularly serious on a rainy day, a dark night, an overcast and/or rainy night, a
foggy day, and many other times with low visibility conditions. Present vision driver assistance
systems are designed to perform under good-natured weather conditions.Classification is a
methodology to identify the type of optical characteristics for vision enhancement algorithms to make
them more efficient. To improve machine vision in bad weather situations, a multi-class weather
classification method is presented based on multiple weather features and supervised learning. First,
underlying visual features are extracted from multi-traffic scene images, and then the feature was
expressed as an eight-dimensions feature matrix. Second, five supervised learning algorithms are used
to train classifiers. The analysis shows that extracted features can accurately describe the image
semantics, and the classifiers have high recognition accuracy rate and adaptive ability. The proposed
method provides the basis for further enhancing the detection of anterior vehicle detection during
nighttime illumination changes, as well as enhancing the driver’s field of vision on a foggy day
