R-CNN源于2014年伯克利大学的这篇论文《Rich feature hierarchies for accurate object detection and semantic segmentation》。其架构和模型训练参数等借鉴了AlexNet,也和同时期的Overfeat也有很多共同之处。R-CNN名字的来源于region proposals和CNN相结合,即具有CNN功能的Regions。其在VOC2012上将mAP(较之前)提高了30%以...

An alternative way to use the project is to copy themrcnnfolder to where the project will be used. Assume there is a directory called “Object Detection” within which there is a Python file namedobject_detection.pythat uses the code in themrcnnfolder. Then, simply copy themrcnnfolder insi...

Deep learning is a powerful machine learning technique that you can use to train robust object detectors. Several deep learning techniques for object detection exist, including Faster R-CNN and you only look once (YOLO) v2. This example trains a Faster R-CNN vehicle detector using thetrainFast...
To evaluate object detection models like R-CNN and YOLO, themean average precision (mAP)is used. The mAP compares the ground-truth bounding box to the detected box and returns a score. The higher the score, the more accurate the model is in its detections. ...
Now you're set to train on the Pascal VOC 2007 data usingpython run_faster_rcnn.py. Beware that training might take a while. Run Faster R-CNN on your own data Preparing your own data and annotating it with ground truth bounding boxes is described inObject detection using Fast R-CNN. ...
In the code sample shown above, an instance of an FRCNNModel class is created and the model is called for detection on a single image. The resulting bounding boxes and their corresponding labels are then printed to the screen. Note that the only parameters required to instantiate the FRCNNMo...
The TensorFlow Object Detection API is an open source framework built on top of TensorFlow that makes it easy to construct, train and deploy object detection models. At Google we’ve certainly found this codebase to be useful for our computer vision needs, and we hope that you will as well...
论文名称中可以看出来:《Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks》——Region Proposal Networks(RPN),相比之前使用selective search的方法人为选定region proposals,在Faster R-CNN中,将此过程砍掉了,提出来用CNN学习的方式自动划分region proposals,即论文中提出region proposal ...
