提出一种基于协同表示的新的目标跟踪算法.在贝叶斯框架下,采用基于重构误差的观测似然函数和考虑遮挡的模型更新机制设计一个鲁棒的跟踪器.用l1范数来建模重构误差以更好地容忍奇异值,同时用协同表示对编码系数进行约束.实验结果表明,和其他算法相比,本文算法能够战胜遮挡、尺度变化、光照变化、背景混乱等干扰因素,具有较高的准确度和鲁棒性. 相似文献

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners. 相似文献

HIV remains a significant health concern entering the fourth decade of the epidemic [Centers for Disease Control and Prevention. 2014. HIV basics. Retrieved from http://www.cdc.gov/hiv/basics/index.html], and people living with HIV continue to grapple with stigma. This study uses Leary and Schreindorfer's [1998. The stigmatization of HIV and AIDS: Rubbing salt in the wound. In V. J. Derlega &; A. P. Barbee (Eds.), HIV and social interaction (pp. 12–29). Thousand Oaks, CA: Sage] conceptualization of stigma to explore prior stigmatization on reasons for and against future disclosures. We interviewed HIV+ individuals (N?=?59) and used a combination of deductive and inductive coding to analyze participants’ responses. Deductive codes consisted of four stigma characteristics (pose a threat to others’ health and safety, deviate from group standards, create negative emotional reactions in others, and failure to contribute), experiences of feeling stigmatized due to HIV status (yes or no), and the degree to which HIV stigma was a concern (major, minor, or no concern). Inductive coding identified examples of perceived and experienced stigma and stigma concerns on future disclosure decision-making. Practical implications discuss individual, institutional, and societal stigma-reduction interventions and programs. 相似文献

This paper examines the effect of modifiers on the stability of a vinyl acetate/ethylene copolymer dispersion adhesive upon aging. Eighteen common modifiers were added to a well-characterized vinyl acetate/ethylene copolymer dispersion (Dur-O-Set® E-150) in known concentrations and dry-film samples were subjected to 16–17 years of dark aging and seven to eight years of light aging. Yellowing, pH, gloss, swelling, cohesive strength, and flexibility were monitored for changes upon aging. Generally, the neat Dur-O-Set® E-150 (no additives) was found to become acidic on aging, but was fairly resistant to yellowing. It also swelled substantially in toluene, was of high gloss, medium strength, and flexible, and remained so on aging. No modifier was found to improve these properties. Various solvents, wetting agents, and thickeners did not alter the properties by much, while plasticizers, freeze-thaw stabilizer, glycerin, and certain fillers had a more negative effect. 相似文献

This ethnographic study examines the practice of Aikido, a martial art style originating from Japan, by a community of non-Japanese practitioners in the southwestern region of the United States. This paper recounts the second nature-making of the art's skillful responsiveness as a thing to be explained from the ground, rather than leaving its cultural dynamics and their appropriative relations unchallenged as a relatively homogenous process of globalization and increased contact. In the case of Shining Energy (a pseudonym), the “taking” of another's cultural elements and “making” it a fully habituated and naturalized way of moving and being (second nature) are predicated on geo-making, the production of ontologizing resources (first nature) that enable culturally sanctioned modes of somatic engagements with the world. The process of appropriating Aikido entails an inversion between the figure and ground that foregrounds the geo-making of the ground/field for activity itself. 相似文献

In this interview, conducted via email during August 2016, Dr. Arlene G. Taylor discusses her career as a cataloger, professor of cataloging and classification, and her work in professional associations. Topics include her early cataloging and teaching experiences, changes in both cataloging practice and the teaching of cataloging, subject analysis, and “aboutness” as compared with form/genre access, professional experiences outside the United States, and the future of MLIS programs. 相似文献
