“…Firstly, we compare the classification performance of the proposed HAD-based approach with the state-of-the-art approaches [16], [24], [10], which reports only binary classification results for the pair-wise combinations of structured vs. structured, structured vs. semi-structured, and semistructured vs. unstructured scenes. The results shown in Table 2 (results for the existing approaches are obtained from the paper [10]) clearly indicates the superior performance of the proposed HAD-based approach, which is also able to perform consistently well for each of the selected three classifiers. The state-of-the-art approaches work by complex interactions among the trajectories to generate a collectiveness measure.…”

“…In contrast, Li et al [25] used a point selection strategy to refine the features points which are tracked, followed by a manifold ranking approach to compute the crowd collectiveness. In an extended work, Li et al [10,26] modelled the motion intention of individuals in a scene by proposing an intention-aware model which is combined with a manifold ranking strategy to compute the collectiveness of the crowd. Recently, Roy et al [27] proposed an approach to classify a given crowded scene into structured, semi-structured and unstructured based on the definitions presented in [15].…”

“…Crowd analysis is still present in papers in 2020. Li et al [58] propose quantifying and detecting collective motion through a multi-stage clustering strategy and a method to provide crowd anomaly detection and localization using histogram of magnitude and momentum [4]. Regarding crowds and environments: Sun et al [95] propose to predict crowd flows using graph convolutional networks.…”

“…Recently, deep learning models have improved the state of the art related to recognizing speech or objects, image processing, signal and information [12,21,23]. For the problem of detection and classification of PQ disturbances, deep neural networks can not only improve the performance, but also automate the process of extraction and selection of features, reducing and simplifying the process, from a threestep process into one unified process.…”
