Abstract

Background and Objectives: Object detection has been a fundamental issue in computer vision. Research findings indicate that object detection aided by convolutional neural networks (CNNs)‌ is still in its infancy despite -having outpaced‌ other methods‌.
Methods: This study proposes a straightforward, easily implementable, and high-precision object detection method that can detect objects ‌‌‌with minimum least error. ‌Object detectors generally fall into one-stage ‌‌and two-stage‌‌ detectors‌‌. Unlike one-stage detectors, two-stage detectors ‌are often more precise, despite performing at a lower speed. In this study, a one-stage‌‌ detector is proposed, and the results indicated its sufficient precision‌. The proposed method uses a feature pyramid network ‌(FPN) to detect objects on multiple scales‌. This network is combined with the ResNet 50 deep neural network.
Results: The proposed method is trained and tested on ‌Pascal VOC 2007 and COCO datasets. It yields a mean average precision (mAP) of 41.91 in Pascal Voc2007 and 60.07% in MS COCO. The proposed method is tested under additive noise. The test images of the datasets are combined with the salt and pepper noise to obtain the value of mAP for different noise levels up to 50% for Pascal VOC and MS COCO datasets. The investigations show that the proposed method provides acceptable results.
Conclusion: It can be concluded that using deep learning algorithms‌ and CNNs‌ and combining them with a feature network can significantly enhance object detection precision.
