Neural features for pedestrian detection

This paper presents a pedestrian detection approach that uses neural features from a fully convolutional network (FCN) instead of features manually designed. We train an AdaBoost detector per layer and compare the performance to find the optimal layer for this task. Combining results of multiple detectors can further improve the performance. In order to adapt the FCN to pedestrian detection task, we fine-tune it with bounding boxes labels. Using neural features generated by fine-tuned FCN, the log-average miss rate (MR) on Caltech pedestrian dataset is 18.79% by a single detector and 16.50% by combining two detectors. We also evaluate the proposed method on INRIA pedestrian dataset and the MR is 11.17% with a single detector and 9.91% through combining two detectors. The improved performance indicates that the proposed neural features are applicable to pedestrian detection task, due to their strong representation. (C) 2017 Elsevier B.V. All rights reserved.
