As shown in Table3, by applying the data argumentation techniques (e.g., image flip, rotation, random deformation, and conditional generative model38), the segmentation accuracy of different competing methods indeed can be boosted. The model also introduces two hyperparameters: width multiplier and resolution multiplier to reduce the channel numbers and reduce the image resolutions, respectively. The high precision and recall show the great performance of the model. Chen, Y. et al. The potential reasons are two-fold. Google Scholar. Fully convolutional networks for semantic segmentation.

(1) The hats with the same shapes and colors or the background are recognized mistakenly as the safety helmets. [Project] Cite this article. That suggests the detection model established in the paper is not accurate enough. A more elegant and effective way is to build a semantic segmentation on fully convolutional networks (FCN) as first demonstrated by Long et al.

According to the accident statistics released by the state administration of work safety from 2015 to 2018, among the recorded 78 construction accidents, 53 events happened owing to the fact that the workers did not wear safety helmets properly, accounting for 67.95% of the total number of accidents [1].

The 3D information of teeth and surrounding alveolar bones is essential and indispensable in digital dentistry, especially for orthodontic diagnosis and treatment planning. Our approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance. As shown in Figure 10(a), the probability predicted by the model is 98%, but the probability of recognizing the background as safety helmets is 78%.

IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI), 33(5):945957, 2011. Then, the samples in the dataset are divided into three parts randomly: training set, validation set, and test set. Then, a dataset of 3261 images containing various helmets is built and divided into three parts to train and test the model. Semantic segmentation with the goal to assign semantic labels to every pixel in an image [1,2,3,4,5] is one of the fundamental topics in computer vision.Deep convolutional neural networks [6,7,8,9,10] based on the Fully Convolutional Neural Network [8, 11] show striking improvement over systems relying on hand-crafted features [12,13,14,15,16,17] on benchmark Yang, Y. et al. Br. Jul. [Paper] This is the common limitation of the-state-of-art algorithms. [18] proposed an increased CNN that integrates Red-Green-Blue, optical flow, and gray stream CNNs to monitor and assess workers activities associated with installing reinforcement at the construction site. To verify the clinical applicability of our AI system in more detail, we randomly selected 100 CBCT scans from the external set, and compared the segmentation results produced by our AI system and expert radiologists. In this work we address the task of semantic image segmentation with Deep Learning and make three main contributions that are experimentally shown to have substantial practical merit. A probabilistic neural network (PNN) is a four-layer feedforward neural network. Jin, L. et al. Previous works cannot conduct all these steps fully automatically in an end-to-end fashion, as they typically focus only on a single step, such as tooth segmentation on predefined ROI region24,25,26,27,28,29,30 or alveolar bone segmentation31,32. Han Hu+, Jiayuan Gu*+, Zheng Zhang+, Jifeng Dai, and Yichen Wei Semantic segmentation is an approach detecting, for every pixel, belonging class of the object. In 2016 Fourth International Conference on 3D Vision (3DV) , 565571 (IEEE, 2016). TP+FN means the actual number of helmets. IEEE Trans Pattern Anal Mach Intell. Article In this regard, we develop a deep learning-based method for the real-time detection of a safety helmet at the construction site. 96, 416422 (1989). Among the 3261 images, 2769 images were divided into the training set, 339 images were divided into the validation set, and 153 images were divided into the test set. In deep learning, a convolutional neural network (CNN, or ConvNet) is a class of artificial neural network (ANN), most commonly applied to analyze visual imagery. a The overall intensity histogram distributions of the CBCT data collected from different manufacturers. [Project] The width of the default boxes is calculated as follows: The height of the default boxes is calculated as follows: When the aspect ratio is 1, a default box size is added: . The proposed GFSAE module is placed between the down-sampling and up-sampling networks for semantic segmentation of large-scale urban street-level point clouds. [Project] Moreover, we also provide the data distribution of the abnormalities in the training and testing dataset. Carousel with three slides shown at a time.

Barone, S., Paoli, A. All the authors discussed the results and commented on the manuscript. 2. The precision of the trained model is 95% and the recall is 77%, which demonstrates that the proposed method performs well in safety helmet detection. First, fully automatic tooth and alveolar bone segmentation is complex consisting of at least three main steps, including dental region of interest (ROI) localization, tooth segmentation, and alveolar bone segmentation. After the training and testing process, the mean average precision (mAP) of the detection model is stable and the helmet detection model is built. The layers are Input, hidden, pattern/summation and output.

Finally, the weights and the parameter values of the safety helmet detection model are trained and obtained through the training process. Specifically, for tooth segmentation, the paired p values are 2e5 (expert-1) and 7e3 (expert-2). We show that convolutional networks by themselves, trained end-to-end, pixels-to-pixels, exceed the state-of-the-art in semantic segmentation. [Project] 50, 116128 (2014). ISSN 2041-1723 (online). However, the working range of the RFID readers is limited and the RFID readers can only suggest that the safety helmets are close to the workers but unable to confirm that the safety helmets are being properly worn.
