Abstract
Object detection models have known important improvements in the recent years. The state-of-the art detectors are end-to-end Convolutional Neural Network based models that reach good mean average precisions, around 73%, on benchmarks of high quality images. However, these models still produce a large number of false positives in low quality videos such as, surveillance videos. This paper proposes a novel image fusion approach to make the detection model focus on the area of interest where the action is more likely to happen in the scene. We propose building a low cost symmetric dual camera system to compute the disparity map and exploit this information to improve the selection of candidate regions from the input frames. From our results, the proposed approach not only reduces the number of false positives but also improves the overall performance of the detection model which make it appropriate for object detection in surveillance videos.
