Road lane line detection is one of the essential modules of ADAS. Lots of advancement has been already done, but most of the recent papers did not consider the wide variability of challenging nighttime conditions. In this paper, a method to detect nighttime lane line under different challenging conditions proposed. This simple technique can reach the real-time computation for ADAS applications and at the same time, can handle multiple challenges at a time. In the beginning, Bilateral Filter has been used to reduce the noise while preserving the edges. Next, we choose an optimized threshold (OT) for the Canny edge detector, which can detect edges under a wide variability of nighttime illumination conditions. After that Region of Interest (ROI) is selected using an equilateral triangle-shaped mask which helps to reduce computation time and remove unwanted edges. After that, lines are extracted by Probabilistic Hough Transform (PHT). Finally, a robust technique Slope and Angle based Geometric Constraints (SAGC) is proposed to remove the non-lane lines extracted by PHT. SAGC reduce false detection significantly. Experimental results show that the average detection rate is 94.05%, and the average detection time is 26.11ms per frame which outperformed state-of-the-art method.","PeriodicalId":294200,"journal":{"name":"2021 IEEE 13th International Conference on Computer Research and Development (ICCRD)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116808300","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}

Soil data analysis is usually related to practice in agricultural production management or discovery in agro-ecosystem process, so it is not easy to obtain labeled data that requires human intervention, and it is also not realistic to set specified pattern in advance. It is desirable to review the research work on soil data analysis using spatial clustering techniques in context of agricultural applications, which is the object of this survey. Soil properties (including physical, chemical, and biological properties) and the characteristics of the spatial soil data are first introduced. Spatial clustering techniques are then summarized in five different categories. Soil data analysis using spatial clustering is reviewed in four categories of agricultural applications: agricultural production management zoning, comprehensive assessment of soil and land, soil and land classification, and correlation study for agro-ecosystem. The traditional clustering algorithms generally work well, and prototype-based clustering methods are more preferred in practice. Some machine learning models can be further introduced into the spatial clustering algorithms for better accommodation to various characteristics of soil dataset.","PeriodicalId":294200,"journal":{"name":"2021 IEEE 13th International Conference on Computer Research and Development (ICCRD)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130799516","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 original intention of the introduction of optical flow is to use the time information contained in video, however, the subsequent work shows that optical flow is useful for action recognition because it is invariant to appearance. In this article, we study and discuss this point of view, and propose optical flow enhancement algorithms to improve action recognition accuracy. Our enhancement algorithms improve the invariance to appearance of the representation in optical flow without losing time information, and every action recognition network with optical flow can benefit from our algorithms. We conduct a series of experiments to validate the influence of the proposed algorithms with TSN in terms of several datasets and optical flow calculation methods. As a result, we prove that first order differential algorithms are effective, TSN with our enhancement module significantly outperform original network. Based on these experiments, we also verify the importance of invariance to appearance in optical flow, and provide a reference for the follow-up study of improving action recognition accuracy.","PeriodicalId":294200,"journal":{"name":"2021 IEEE 13th International Conference on Computer Research and Development (ICCRD)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126700344","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}

To solve the problem of RIFT algorithm registration model, the thin-plate spline model is used instead of the rigid registration model to improve the algorithm. After image feature matching, the thin-plate spline is used to construct the image transformation model, and the image space transformation is decomposed into global affine transformation and local non-affine transformation, and the whole image and local mapping transformation are realized at the same time without local distortion. Experiments show that the improved algorithm can increase the CMR by 5%. The specific registration strategy is as follows: firstly, two kinds of data are preprocessed, and the image of the cloud depth map of the production point of the regular-grid resampling model is used. Then, the improved RIFT algorithm is used to extract corner points and edge points as registration elements, and Euclidean distance is used as similarity measure to achieve the registration of point cloud depth map and optical image, and then indirectly achieve the registration of laser point cloud and optical image. Finally, the registration accuracy is analyzed from the visual level and pixel level. The results show that the improved RIFT algorithm has favorable registration effect on point cloud depth map and optical image, and the proposed method has exceptional validity and reliability.","PeriodicalId":294200,"journal":{"name":"2021 IEEE 13th International Conference on Computer Research and Development (ICCRD)","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115246004","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}

These domain names are used to evade domain based security detection and mitigation controls such as firewall controls. Existing prevalent techniques to detect DGA domains such as reverse engineering malware samples and statistical analysis techniques are time consuming, can be easily circumvented by attackers, and need contextual information which is not easily or feasibly obtained. Due to this, the use of machine learning and deep learning techniques to detect DGA domains has picked up significant interest in the cyber security and analytics communities. The ultimate goal is to detect DGA domains on a per domain basis using the domain name only, with no additional information. As with all techniques, there is the possibility of false positives: valid domains being detected as DGA domains. This paper explores the possible use cases that can result in false positives for DGA domain detection using machine learning and deep learning techniques, and how such use cases, if not uniquely addressed within an automated system or model or technique, can also be used as attack vectors by attackers using DGA domains.","PeriodicalId":294200,"journal":{"name":"2021 IEEE 13th International Conference on Computer Research and Development (ICCRD)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122622898","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}
