However, using these algorithms for real-time detection suffer from low FPS and accuracy. In this paper, we enhanced the conventional SSD as research has shown that it has higher FPS and accuracy compared to others making it more suitable for real-time object detection. However, this conventional SSD suffers computational complexity and low accuracy for small objects detection. We proposed an enhanced SSD for real-time object detection to improve the accuracy of conventional SSD and reduce its computational complexity with a higher FPS. Our main contribution is at the level of the multi-scale object detection, where we implemented PIV layers for enhanced localization and detection of objects in the feature layers. Furthermore, we introduced extended dilated convolutions with different dilation operations thereby increasing the receptive field and improved the detection of objects. To demonstrate the effectiveness of our proposed method, we first carried out experiments on PASCAL VOC 2007 and PASCAL VOC 2012 and achieved improved performances in mAP of 82.0 and mAP of 85.6 on PASCAL VOC 2007 and PASCAL VOC 2012 respectively at 63 FPS, with input size of 300x300 for a batch size of 8. Using the same experimental approach, we further demonstrated the versatility of the proposed method on the underwater image dataset where we achieved also improved performance in mAP of 79.1. Our experimental results have shown to be an effective alternative for real-time objection detection to the conventional SSD and other state-of-the-art architectures.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127079513","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 highlight on the desktop is random sampling of virtual point light sources, which do not exist and are only used as the medium of energy transfer. Here is a schematic effect, so all the virtual point lights are drawn. It can be seen that the number of virtual point lights is very large, and the distribution is random. At the same time, the light red on the desktop comes from the virtual point light sampled from Stanford dragon. Due to the strict requirements for the restoration of the real color in the rendering of cultural relics, there is a color deviation problem in the transmission of virtual point light source energy through the above completely non physical means, so it does not meet the demand of high fidelity. In this paper, a new virtual point light sampling method is established, which can effectively obtain the shadow map of the sampled virtual point light source. Under the condition of ensuring frame rate, the correctness of light energy transmission is guaranteed to the greatest extent. At the same time, it can inherit the advantages of the original RSM (Reflective Shadow Maps).","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128386863","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}

For problems with large-displacement or large-deformation boundaries, mesh cells near the boundaries are often excessively stretched or compressed, thus it's hard to maintain a high-quality mesh. To deal with the distorted cells, this paper adopts the mesh refinement method based on the open source software OpenFOAM. In order to achieve the desired effects of localization and adaptation, we propose an adaptive length scale estimation algorithm based on the specified growth factor and current edge lengths. Considering the inconsistency problems for the original implementation of parallelization, an optimized multi-threaded master/worker model is developed for the process of edge checking. Experiments show that our adaptive length scale estimation algorithm works well for moving boundary problems. Compared to the original mesh deformation, using the adaptive mesh refinement could greatly improve the mesh quality. In parallel testing, all the results are consistent and a maximum speedup of 3.8 is achieved on a computing node of 24 cores.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131464984","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}

But in practice the h index is insensitive to high-quality papers in all papers published by scientists. By giving weight to high-quality papers, this paper puts forward a new index: index. It makes up for this deficiency. The index is improved on the basis of the traditional h-index which gives weight to different levels of papers published by scientists and evaluates the academic influence of scientists with a weighted h index.

Empirical analysis shows that the index can evaluate the academic level of scientists steadily, has a better differentiation from the h index, and the index can better highlight the index level of scientists with high paper quality and can appropriately reduce the index level of scientists with lower paper quality.This paper proposes a new index.While retaining the characteristics of simplicity, ease of use and easy calculation, it is effective, reasonable and can be popularized in practical application.","PeriodicalId":354966,"journal":{"name":"Proceedings of the 5th International Conference on Computer Science and Application Engineering","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132596295","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}
