This paper presents a framework of integrating a mixture of part-based models and region-based convolutional networks for accurate and efficient object detection. Each mixture component consists of a small number of parts accounting for both object aspect ratio and contextual information explicitly. The mixture is category-agnostic for the simplicity of scaling up in applications. Both object aspect ratio and context have been extensively studied in traditional object detection systems such as the mixture of deformable part-based models [13]. They are, however, largely ignored in deep neural network based detection systems [17, 16, 39, 8]. The proposed method addresses this issue in two-fold: (i) It remedies the wrapping artifact due to the generic RoI (region-of-interest) pooling (e.g., a 3 x 3 grid) by taking into account object aspect ratios. (ii) It models both global (from the whole image) and local (from the surrounding of a bounding box) context for improving performance. The integrated framework is fully convolutional and enjoys end-to-end training, which we call the aspect ratio and context aware fully convolutional network (ARC-FCN). In experiments, ARC-FCN shows very competitive results on the PASCAL VOC datasets, especially, it outperforms both Faster R-CNN [39] and R-FCN [8] with significantly better mean average precision (mAP) using larger value for the intersection-over-union (IoU) threshold (i.e., 0.7 in the experiments). ARC-FCN is still sufficiently efficient with a test-time speed of 380ms per image, faster than the Faster R-CNN but slower than the R-FCN. |
