Abstract EN
Weather recognition based on outdoor images is a brand-new and challenging subject, which is widely required in many fields.
This paper presents a novel framework for recognizing different weather conditions.
Compared with other algorithms, the proposed method possesses the following advantages.
Firstly, our method extracts both visual appearance features of the sky region and physical characteristics features of the nonsky region in images.
Thus, the extracted features are more comprehensive than some of the existing methods in which only the features of sky region are considered.
Secondly, unlike other methods which used the traditional classifiers (e.g., SVM and K-NN), we use discriminative dictionary learning as the classification model for weather, which could address the limitations of previous works.
Moreover, the active learning procedure is introduced into dictionary learning to avoid requiring a large number of labeled samples to train the classification model for achieving good performance of weather recognition.
Experiments and comparisons are performed on two datasets to verify the effectiveness of the proposed method.
