چکیده
Abstract This paper studies the target detection algorithm based on Faster R-CNN. Aiming at insufficient regression accuracy of prediction box, an improved R-CNN is proposed. Firstly, ResNet 50 residual network selected and feature pyramid (FPN)is introduced to improve ability detection. Secondly, GIOU optimize anchor frame positioning problem candidate frame. Finally, a bilinear interpolated ROI Alian used replace original pooling, which avoids pixel error caused by two quantization operations. The data set Pascal VOC 2012 for training testing, it verified that proposed improves mAP 5.4% compared with algorithm.

Face Detection Using Improved Faster RCNN
Faster RCNN has achieved great success for generic object detection including PASCAL object detection and MS COCO object detection. In this report, we propose a detailed designed Faster RCNN method named FDNet1.0 for face detection. Several techniques were employed including multi-scale training, multi-scale testing, light-designed RCNN, some tricks for inference and a vote-based ensemble metho...

In this report, we present a new face detection scheme using deep learning and achieve the state-of-the-art detection performance on the well-known FDDB face detetion benchmark evaluation. In particular, we improve the state-of-the-art faster RCNN framework by combining a number of strategies, including feature concatenation, hard negative mining, multi-scale training, model pretraining, and pr...
متن کاملRevisiting RCNN: On Awakening the Classification Power of Faster RCNN
Recent region-based object detectors are usually built with separate classification and localization branches on top of shared feature extraction networks. In this paper, we analyze failure cases of state-ofthe-art detectors and observe that most hard false positives result from classification instead of localization. We conjecture that: (1) Shared feature representation is not optimal due to t...

Tracking and detecting of object is one of the most popular topics recently, which used for motion detection of various objects on a given video or images. To achieve the goal of intelligent navigation of a moving platform operating on the sidewalk, our goal is to build the software that is able to detect the pedestrians and predict their trajectories, during which process MOT (multiple object ...
متن کاملKeypoint Density based Region Proposal for object detection using rCNN
Recent changes to the topology of regional convolutional neural networks (rCNN) have allowed them to obtain near realtime speeds in image detection. We propose a method for region proposal alternate to selective search which is used in the current state of the art object detection [3] and introduce the fine grained image datasets. In a maritime surveillance setting, it maybe important to not on...
