This paper proposes a crowd counting method. Crowd counting is difficult because of large appearance changes of a target which caused by density and scale changes. Conventional crowd counting methods generally utilize one predictor (e,g., regression and multi-class classifier). However, such only one predictor can not count targets with large appearance changes well. In this paper, we propose to predict the number of targets using multiple CNNs specialized to a specific appearance, and those CNNs are adaptively selected according to the appearance of a test image. By integrating the selected CNNs, the proposed method has the robustness to large appearance changes. In experiments, we confirm that the proposed method can count crowd with lower counting error than a CNN and integration of CNNs with fixed weights. Moreover, we confirm that each predictor automatically specialized to a specific appearance.

本论文提出了一种群众计数方法，该方法使用多个针对特定外观的 CNN 进行预测，这些 CNN 根据测试图像的外观被自适应地选择，从而具有对大尺度外观变化的鲁棒性，并且可以比 CNN 和固定权重的集成方法更准确地计算群体数量。
