The mass screening of populations for DR is time-consuming. Therefore, computerized diagnosis is of great significance in the clinical practice, which providing evidence to assist clinicians in decision making. Specifically, hemorrhages, microaneurysms, hard exudates, soft exudates, and other lesions are verified to be closely associated with DR. These lesions, however, are scattered in different positions and sizes in fundus images, the internal relation of which are hard to be reserved in the ultimate features due to a large number of convolution layers that reduce the detail characteristics. In this paper, we present a deep-learning network with a multi-scale self-attention module to aggregate the global context to learned features for DR image retrieval. The multi-scale fusion enhances, in terms of scale, the efficacious latent relation of different positions in features explored by the self-attention. For the experiment, the proposed network is validated on the Kaggle DR dataset, and the result shows that it achieves state-of-the-art performance.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114995233","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}

This method first extracts features from the original image through the improved Darknet53 network. In this process, the 104*104 size feature map after the first residual error in the second stage is additionally output as a fourth-scale feature map. Combine this feature map with the feature maps output from the original 3 stages to form 4 feature map outputs of different scales. Secondly, it uses FPN to down-sample and up-sample the feature maps of 4 scales, and to merge them to output 52*52 scales. Then, the feature map and the positional encoding are combined and input into the Transformer to obtain the data, and the category and position information of the predicted object are output through FFNs. On the COCO2017 data set, the accuracy has been improved compared with other models.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114349831","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}

Multilayer perceptron (MLP) is commonly used in day-ahead photovoltaic forecasting, which has excellent performances in convergence speed and a disadvantage of easily causing overfitting. An ensemble model of MLP is proposed in this paper to counteract the overfitting and reduce the variance of a single MLP model. The input of the ensemble model for day-ahead photovoltaic forecasting comprises feature vectors and the 24-hour power generation of the nearest day. The connection coefficients between MLP are defined by the discounting of feature distance, which measures the dissimilarity between input feature vectors. The forecasting results of a PV system in Macau verifies the effectiveness of the proposed ensemble model of MLP for solving day-ahead photovoltaic forecasting problems.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116347795","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}

When the texture information in the scene is missing, it affects the accuracy of pose estimation and mapping. In the artificial structured environment, there are a lot of structured lines that can be utilized. Compared with point features, line features contain richer information. For example, structure lines can be used to construct surface features. To improve the robustness and stability of visual SLAM positioning in a low-texture environment, we propose a new point-line feature Visual inertial navigation system based on traditional SLAM method, which makes full use of the structural line features in the scene. Compared to the traditional SLAM system which use point-line features, we adopt a new point-line feature error reprojection model-cross-product of between projection line feature and detected line feature and nonlinear optimization strategy under long line, aiming to increase the robustness in a low-texture environment. The proposed algorithm has been verified by EuRoc dataset and real-world scenarios, and the results show that our algorithm has a greater improvement in accuracy.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130837594","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}

The greatest challenge in this direction includes occlusion, truncation, lighting conditions, and complex backgrounds. In order to improve the accuracy and detection speed of vehicle detection, a dynamic scaling network is proposed that assists in constructing a balanced shape neural network to achieve optimum accuracy with minimal hardware. The net architecture is influenced by YOLOv5 and is composed of Cross-Stage Partial Network (CSPNet) as its backbone. In order to go even further, we have proposed an auto-anchor generating method that makes the network suitable for any datasets. Our neural network is fine-tuned by using activation, loss, and optimization functions so as to get the optimum results. Our experimental results demonstrate that the proposed net provides comparable performance of YOLOv4 and Faster R-CNN based on KITTI dataset as the benchmark.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125536528","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}

This kind of method is based on the projection of a light pattern onto the scene captured by a camera. Our originality comes from the projected pattern used, since unlike literature methods, our light projector is a simple conical diving light. With a light cone, the recovered pattern in the image is a closed 2D curve we extract with a light contour detection method we have developed. A specific calibration method has also been created to estimate the cone geometry with respect to the camera. Therefore, we get a calibrated projector-camera pair, we can use to find matches between projected and recovered patterns. Our last contribution is the recovery of 3D data by triangulation using the camera cone relationship and the extracted closed 2D curve. The experimental results that will be presented in this article show the feasibility of the method.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124934192","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}

Many researchers have been devoted to protecting the face template. Nevertheless, to achieve high security for the face template, partial matching accuracy is usually sacrificed. The main challenge of this problem is the low inter-user variations and high intra-user variations of facial images. In this work, we propose a method integrating residual learning and error-correcting codes for face template protection. In particular, the proposed method consists of two major components: (a) a deep residual network component mapping facial images to polar codewords assigned to users, and (b) a polar decoder reducing noise brought by high intra-user variations in the predicted codewords. The proposed method is evaluated on extended Yale B, CMU-PIE, and FEI databases. It provides high security of face template and achieves a high (100%) genuine accept rate at a low false accept rate (0%) simultaneously, which outperforms most state-of-the-arts.","PeriodicalId":143540,"journal":{"name":"Proceedings of the 4th International Conference on Control and Computer Vision","volume":"27 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133761760","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}
