Abstract: A multi-scale algorithm was proposed to detect the targets flexibly. In coarse scale, an optimized DPM (Deformable Part Model) method was used to filter out sparse objectives that was represented by whole body. Then the whole scenario was cut into multiple finer regions and the Faster R-CNN (Region-based Convolutional Neural Network) method was trained and utilized to detect dense objects that was indicated by head in fine scale. These two detection results were incorporated via NMS (Non - Maximum Suppression) method, in order to supplement with each other and remove redundancy. The effectiveness of the proposed method has been proved comparing detect accuracy with DPM and R-CNN individually in the final experiment.

Key words: dense crowd target detection, multi-scale detection, DPM, Faster R-CNN
