- Abstract:
-
To improve the accuracy of the detection of multiple small targets using the faster R-CNN model, we propose a multi-task enhanced dam-crack image detection method based on faster R-CNN (ME-Faster R-CNN). In addition, to solve the problem of insufficient dam-crack samples, we propose a transfer learning method, multi-source adaptive balance TrAdaBoost based on K-means (K-MABtrA), to assist with network training. In the ME-Faster R-CNN, the ResNet-50 network is adopted to extract features from original images, obtain the feature map, and input a multi-task enhanced region-proposal-network module to generate candidate regions by adopting the appropriate size and dimensions of the anchor box. Lastly, the features map and candidate regions are processed to detect dam cracks. The K-MABtrA method first uses K-means clustering to delete unsuitable images. Then, models are trained using the multi-source adaptive balance TrAdaBoost method. Our experimental results show that the proposed ME Faster R-CNN with the K-MABtrA method can obtain an 82.52% average intersection over union (IoU) and 80.02% mean average precision (mAP). Compared with Faster R-CNN detection method using the same parameters, the average IoU and mAP values was increased by 1.06% and 1.56%, respectively.
