Therefore, dividing the crowd flow into regions with basically consistent motion states can help us better understand and analyze the crowd's motion states. For this reason, a deep motion transformation network is proposed to segment the crowd flow into different motion states, which avoids the problem of parameter selection based on the clustering method. We test the method in different crowd density scenarios, and the experimental results show that the proposed method can achieve a better segmentation effect than the previous methods.","PeriodicalId":326682,"journal":{"name":"2021 6th International Conference on Multimedia and Image Processing","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134263396","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}

Yet texture is not precisely defined, which is difficult to be separated from edges. In this paper, a novel texture extraction algorithm was proposed. Nonlinear structure tensor was introduced to distinguish textures out from edges. And an 8-neighborhood tensor inhomogeneous average sparse matrix was presented to smooth the images. The smoothness weights are determined by the local anisotropy. By applying this inhomogeneous average sparse matrix to the input images, the textures are smoothed to the detail layer while the edges are remained in the original images. The effectiveness of our method was demonstrated by the comparison results with other existing generally acknowledged texture extraction algorithms. And the sparse matrix framework reduces the computational cost than the convolution frameworks.","PeriodicalId":326682,"journal":{"name":"2021 6th International Conference on Multimedia and Image Processing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132564753","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 view of the problem of low detection accuracy and low processing speed, a vehicle detection method based on Improved Deep Structure is proposed in this study. Due to the characteristics of highway vehicles with a fixed aspect ratio, k-means ++ clustering method is used to select new anchor boxes to eliminate false targets at an early stage followed by improved depth structure with deep sort. Experimental results demonstrated that our proposed method on standard data set KITTI-UA achieved higher precision and faster speed than the existing algorithms.","PeriodicalId":326682,"journal":{"name":"2021 6th International Conference on Multimedia and Image Processing","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116332123","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, AKAZE is used to extract feature points to ensure the accuracy of feature detection, and then the FREAK operator is used to calculate the descriptor, and then the VFC algorithm is used to perform accurate matching to improve the matching efficiency, and finally the weighted fusion algorithm is used to fuse the image. The research results show that compared with the traditional SIFT, the improved AKAZE algorithm improves the feature extraction time by about 1.11s, and the improved AKAZE algorithm in terms of computing descriptor efficiency increases the time by 1.32s than the SIFT and AKAZE algorithms, which can get higher The accuracy and matching results of the UAV realize rapid and seamless splicing of UAV images.","PeriodicalId":326682,"journal":{"name":"2021 6th International Conference on Multimedia and Image Processing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122162757","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}
