报告题目1：Performance-Enhancing Deep-learning Models for Crowd Counting
报告内容： Counting people or objects with significantly varying scales and densities has attracted much interest from the research community and yet it remains an open problem. Although many attempts have been reported, real world problems, such as huge variation in subjects’ sizes in images and serious occlusion among people, make it still a challenging problem. In this talk, an Adaptive Counting Convolutional Neural Network (A-CCNN), which considers the scale variation of objects in a frame adaptively, is presented. Then, a pruning strategy is presented to remove the irrelevant filters, of which feature maps contain little information, and the negative filters, which are determined by a mask learned on a training dataset. Last, a simple but efficient and effective network, named DENet, is introduced. It is composed of two components, i.e., a detection network (DNet) and an encoder-decoder estimation network (ENet). The proposed models are evaluated on the ShanghaiTech dataset, UCF dataset, WorldExpo’10 dataset etc. to show their superiority compared with the state-of-the-art methods.
