The color, shape, and other appearance characteristics of the flame emitted by different flame engines are different. In order to make a preliminary judgment on the category of the device to which it belongs through studying exterior characteristics of the flame, this paper uses the flame of matches, lighters, and candles to simulate different types of flames. It is hoped that the flames can be located and classified by detecting the characteristics of flames using the object detection algorithm. First, different types of fire are collected for the dataset of experiments. The mmDetection toolbox is then used to build several different object detection frameworks, in which the dataset can be trained and tested. The object detection model suitable for this kind of problem is obtained through the evaluation index analysis. The model is ResNet50-based faster-region-convolutional neural network ( Faster R- CNN), whose mean average-precision ( mAP) is 93.6% . Besides, after clipping the detected flames through object detection, a similarity fusion algorithm is used to aggregate and classify the three types of flames. Finally, the color components are analyzed to obtain the red, green, blue ( RGB) color histograms of the three flames. 相似文献

In this paper, deep learning technology was utilited to solve the railway track recognition in intrusion detectionproblem. The railway track recognition can be viewed as semantic segmentation task which extends imageprocessing to pixel level prediction. An encoder-decoder architecture DeepLabv3 + model was applied in this workdue to its good performance in semantic segmentation task. Since images of the railway track collected from thevideo surveillance of the train cab were used as experiment dataset in this work, the following improvements weremade to the model. The first aspect deals with over-fitting problem due to the limited amount of training data. Dataaugmentation and transfer learning are applied consequently to rich the diversity of data and enhance modelrobustness during the training process. Besides, different gradient descent methods are compared to obtain theoptimal optimizer for training model parameters. The third problem relates to data sample imbalance, cross entropy(CE) loss is replaced by focal loss (FL) to address the issue of serious imbalance between positive and negativesample. Effectiveness of the improved DeepLabv3 + model with above solutions is demonstrated by experimentresults with different system parameters. 相似文献
