Crowd counting, for estimating the number of people in a crowd using vision based computer techniques, has attracted much interest in research community. 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) is introduced and it takes into account the scale variation of objects in a frame adaptively so as to improve the accuracy of counting. The proposed method takes advantages of contextual information to provide more accurate and adaptive density maps and crowd counting in a scene. Extensively experimental evaluation has conducted using different benchmark datasets for object-counting, and shows that the proposed approach is effective and outperforms state-of-the-art approaches.
