A smart home safety environment detection system based on the AT89C51 microcontroller is proposed to solve it. The design uses a ZPH01 PM2.5 detector, MQ7 carbon monoxide (CO) sensor, DHT11 temperature and humidity sensor, and MQ2 smoke sensor. It can achieve the detection, display and alert of indoor temperature, humidity, carbon monoxide concentration, PM2.5 concentration and smoke concentration. At the same time, the HC-SR501 human body sensor module is used to detect the movement of the indoor area in real-time and send alerts. Also, the Principal Component Analysis (PCA) face recognition method is used to realize the recognition of humans at access control. The simulation results show that the designed system can detect the quality of the home environment in real-time and identify the personnel, significantly improving the home environment’s safety factor and quality of life.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Satellite observations provide all-weather and multi-directional observations, facilitating the timely detection of such weather systems, which is crucial to saving lives and property. However, previous methods based on channel feature extraction and threshold filtering did not make full use of information in satellite images, which led to limitations on such complex problems as strong convection detection. In this study, we propose a novel framework of a deep learning-based model Convection-UNet to detect convection. We use channel 4 to 7 of FY-4B GHI that we select according to the microphysical properties of convection as input and radar reflectivity as label. We combine the detailed training time and test time data augmentation strategies and build a deep neural network to automatically extract spatial context features and achieve end-to-end learning. Results show that the performance of our method far exceeds the previous channel extraction combined with threshold filtering methods such as BT and BTD at least 0.24 on Fi-measure. We also show that our channel selection and data augmentation strategies are of great significance to detect convection.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134511157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As nodes join or leave social networks, the relationships between nodes are establishing or terminating, which affects community structure changes. Given the social networks discovery algorithm of static community lacks the indispensable historical information of network community nodes, resulting in insufficient network structure analysis and clustering information. Based on the community network evolution division events, the paper extracted the priority for analysis and proposed the SC-DCDA: Spectral Clustering Based Temporal Community Discovery Algorithm. According to experimental observation, the SC-DCDA firstly reduced the dimensionality of high-dimensional data leveraging the method of spectral mapping. Secondly, the improved Fuzzy C-means clustering algorithm was adopted to determine the correlation between nodes in temporal social networks and the communities to be discovered, and finally the community structure analysis was performed according to the evolutionary similarity matrix. The ground truth datasets combined with the typically community discovery algorithm metric Modularity Score experimental verification and performance evaluation. The experimental results show that the algorithm metric is well-suited for the temporal datasets, indicating that the proposed algorithm has achieved several better results in information interaction, clustering effect, and accuracy.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133266116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional SLAM relies on point features to estimate camera pose, which makes it difficult to extract enough point features in low-texture scenes. When the camera shakes violently or rotates too fast, the robustness of a point-based SLAM system is poor. Aiming at the problem of poor robustness of the existing visual SLAM (synchronous localization and mapping technology) system, based on the ORB-SLAM3 framework, the point feature extractor is replaced with a self-supervised deep neural network, and a matching filtering algorithm based on threshold and motion statistics is proposed to eliminate point mismatch, this significantly accelerates the system’s real- time and accuracy. Likewise, linear activities are integrated into the front-end information extraction, a linear feature extraction model is established, approximation linear features are merged and processed, and the linear feature description and mismatching eradication process are simplified. Finally, the weight allocation idea is introduced into the construction of the point and line error model, and the weight of the point and line is reasonably allocated according to the richness of the scene. Experiments on absolute error trajectory on the TUM dataset emphasize that the revised algorithm increased efficiency and stability when compared to the ORB-SLAM3 system.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116971010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing FFS methods usually adopt a simple convolutional structure as the backbone, which suffers from poor feature extraction ability. In order to address this issue, a novel few-shot segmentation network based on dual-branch feature extraction (DFESN) is proposed. First, an attention-enhanced ResNet is used as the local feature extraction branch. Specifically, we in-corporate channel attention operations into each building block of ResNet to model the importance among channels, which enables DFESN to learn important class information for the segmentation task. Besides, we introduce a Vision Transformer as the global feature extraction branch. This branch leverages the multi-head self-attention mechanism in Vision Transformer to model the global dependencies of support and query image features, further enhancing the feature extraction capabilities of DFESN. We conduct experiments on the PASCAL-5i dataset and demonstrate the superiority of our DFESN.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124267186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, We trained several deep learning algorithm models based on YOLOv5, YOLOv8x, Faster R- CNN and Mask R-CNN with 4 types of lesion features commonly found in 1024 images, from which we selected the algorithm with the best automatic feature recognition effect and optimized the model to further improve the recognition efficiency. Combining the complexity of lesion features and experimental results, we propose a YOLOv8x model based on RepEca network structure and ESE attention mechanism, which is more effective than the original YOLOv8x in application, with an F1 metric value of 71.19%, and can better identify lesion features in images, assisting clinicians to improve the diagnostic accuracy and treatment effect.","PeriodicalId":221346,"journal":{"name":"2023 International Conference on Pattern Recognition, Machine Vision and Intelligent Algorithms (PRMVIA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130444002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
