It is performed with a novel method, mainly combining idea of signed pressure force function with Legendre polynomials. The advantages of the proposed method are as follows. On the one hand, a controlled signed pressure force function based on 1-D Legendre polynomials (LPSPF) can stop the final contours at blurred and multiple objects edges, especially for nuclei images segmentation. On the other hand, we set multiple ball contour as initial contour to automatically detect the exterior and interior boundaries in the image. Ultimately, an improved edge stopping function is applied to fast and robustly capture the edge of multiple regions of interest (ROI). Experimental results demonstrate that our method is higher and faster accuracy than other models on nuclei images and other images with large size, or low-contrast.","PeriodicalId":415288,"journal":{"name":"Proceedings of the International Conference on Advances in Computer Technology, Information Science and Communications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128159964","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}

Based on the research of target recognition technology and its engineering application, this paper proposes a target recognition method based on rectangular geometric features. Firstly, a linear feature extraction method based on this condition is proposed, which is used to identify the straight line on the edge of a rectangular object. Based on the Hough transform, the problem is transformed into a multi-constraint optimization model, and the whale optimization algorithm is used to solve the model to achieve accurate identification of features in complex backgrounds. The experimental results show that the method can effectively detect the target features even if the number of lines in the image varies greatly, which has better robustness and can improve the engineering execution efficiency.","PeriodicalId":415288,"journal":{"name":"Proceedings of the International Conference on Advances in Computer Technology, Information Science and Communications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123312130","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}

Based on a comprehensive analysis, the output spectrum expression is established and simulated numerically. The results of numerical simulation indicates that when the length difference of interference arms and the coupling coefficient of the couplers are some certain values, it will obtain a uniform flat-top passband and similarity to rectangular output spectrum. The improved interleaver has a wider 0.5dB passband bandwidth and 25dB stopband bandwidth, and the rejection in stopband and the roll-off in transition band are improved remarkably. The device has a certain ability to resist the deviation, which reduces the difficulty degree of making it. The design and analysis should be useful in the realization of flattop all-fiber interleaver for development in dense wavelength division multiplexing (DWDM) networks of high spectral efficiency.","PeriodicalId":415288,"journal":{"name":"Proceedings of the International Conference on Advances in Computer Technology, Information Science and Communications","volume":"327 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122638607","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 recover the shadow area, in existing methods, fringe patterns from multiple projectors are employed to calculate the absolute phase maps of entire object surface. However, if the fringe order errors in the absolute phase maps were not corrected, significant errors would appear on the reconstructed three-dimensional result. In this paper we propose a method to recover the entire surface profile with the fringe projections from two projectors. In the proposed method, the shadow areas are identified, a novel technique is developed to correct the fringe order errors in the absolute phase maps of the fringe patterns from two projectors, thus the reliability of shadow area recovery could be improved. This method also can be used for various applications in industries and academics. The methodology is exemplified with experimental data.","PeriodicalId":415288,"journal":{"name":"Proceedings of the International Conference on Advances in Computer Technology, Information Science and Communications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633032","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}

Since the fundamental of state-of-the-art detectors, large-scale annotated datasets, is cost-consuming, few-example logo detection is imperative and thought-provoking. In this paper, a three-stage Few-example Logo Detection Refined System (FLDRS) is proposed to detect logo with a few annotated samples. Specifically, the proposed detector is first initialized using large-scale generic target detection dataset with annotations, such as ImageNet, then further updated with large amount of synthetic logo images, and finally refined with a few annotated real examples. To make synthetic data more closer to real scene, a copy-paste-blend strategy is also presented in our model which not only characterizes many kinds of possible logo transformations but also takes the environment attribute of the logo type into consideration. The superior performance in FlickLogo32 dataset demonstrates the efficiency of the proposed FLDRS.","PeriodicalId":415288,"journal":{"name":"Proceedings of the International Conference on Advances in Computer Technology, Information Science and Communications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125986621","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}

We incorporate technological opportunity as moderator. Our result indicates that patent portfolio with larger size and broader technical scope can have a positive effect on firm performance, but a more diverse patent portfolio can have a negative effect on firm performance.
