Currently, Feature Pypyramid Networks(FPN) structure is usually used in pedestrian detection networks for feature extraction but aiming at the characteristics of pedestrian detection tasks it may not be effective in extracting important layer feature information. Therefore, this paper proposes a module based on PFN structure with parallel feature fusion named PFF-FPN. PFF-FPN uses three different FPNs to extract feature and fuses the corresponding layer feature to reinforce the focused layer feature information. In pedestrian detection task PFF-FPN can be adapted to different network frameworks and it also gets a good performance.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129497378","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 paper presented the characteristics of wind field near various special microtopography in an eastern coastal area with numerical simulation. It was demonstrated that Micro-topography has a great influence on wind field: there will be a phenomenon near the top of the mountain that wind speed increases locally and then flows back, which will be weakened by the shielding effect of the mountain in front; There will be obvious wind acceleration effect in the windward pass, on the contrary, there will be wind deceleration effect in the downwind pass; The variation law of wind speed and wind speed ratio along the slope track is similar to the Slope gradient, when the gradient changes, the wind speed will fluctuate.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126588716","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}

First, we remove the time-consuming dense optical flow prediction network in GeoNet. We propose a method for image reconstruction at one frame interval to solve large displacement between moving objects. Second, we propose a way to find the best pixel to solve the problem of pixel occlusion in the image. Third, to further solve the uneven illumination of the image and the degradation of image quality, we propose an adaptive histogram equalization based on limited contrast to enhance the image. A large number of experimental demonstrations have been carried out on the KITTI public dataset. The experimental results show that our network reduces the time cost and complexity on the general evaluation index. It has a significant improvement compared with GeoNet and has achieved more accurate in-depth and position prediction results.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127424535","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}

Optimizing grouping algorithms can significantly improve the performance of pose estimation. In this paper, we introduce body center, a center point of person instance, and anchor point, a corresponding assistant position point, for the task of grouping. The anchor point is the center of joint and body center, which can help joint grouping to the corresponding person instance like an anchor. The body center and anchor point can be predicted simultaneously with the joint candidate by the same backbone. So, this new grouping method can fully exploit the features extracted by the step of joint detection. On the COCO keypoints dataset, the proposed method performs on par with the existing state-of-the-art bottom-up method in accuracy.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130344989","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}

Seven types of commonly used microcatheter heads were used for X-ray fluoroscopy on Siemens digital flat panel angiography machine, and the fluoroscopy of the distal radiopaque marker was observed. Six samples from each brand were selected to measure the distance between the head end of the microcatheter and the distal development ring, and the difference in length was compared. Six microcatheters of each brand were selected for steam fumigation and shaping according to the instructions. Thereafter, the endovascular treatment process of intracranial aneurysms was simulated to compare their shaping ability and stability after plasticity. After fluoroscopy on the digital flat panel angiography machine, the distal markers of Echelon-14 and Prowler-14 were highly recognizable by naked eyes. In the distance detection test between the head end of each microcatheter and the distal radiopaque marker, the distance between the head end of the Presgo-14 microcatheter and the distal radiopaque marker was the shortest (0.492 mm), while the Echelon-10 microcatheter was the longest (0.866 mm). In the endovascular treatment experiment of steam fumigation shaping simulated intracranial aneurysms, Headway-17 microcatheter had the best shaping ability and stability after shaping, and Presgo series microcatheter had similar shaping retention ability to Echelon series microcatheter. All types of microcatheters have their own characteristics. Extensive understanding of the characteristics of different brands of microcatheters will facilitate their better application in nerve endovascular treatment.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131837202","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}
