We present a new optimization based parsing framework for the geometric analysis of a single image coming from a man-made environment. This framework models the scene as a composition of geometric primitives spanning different layers from low level (edges) through mid-level (lines segments, lines and vanishing points) to high level (the zenith and the horizon). The inference in such a model thus jointly and simultaneously estimates (a) the grouping of edges into the line segments, (b) the grouping of line segments into the straight lines, (c) the grouping of lines into parallel families, and (d) the positioning of the horizon and the zenith in the image. Such a unified treatment means that the uncertainty information propagates between the layers of the model. This is in contrast to most previous approaches to the same problem, which either ignore the middle levels (line segments or lines) all together, or use the bottom-up step-by-step pipeline.For the evaluation, we consider a publicly available York Urban dataset of "Manhattan" scenes, and also introduce a new, harder dataset of 103 urban outdoor images containing many non-Manhattan scenes. The comparative evaluation for the horizon estimation task demonstrate higher accuracy and robustness attained by our method when compared to the current state-of-the-art approaches.
The article is devoted to the assessment of the impact of air transport on the development of the tourism industry. It has been established that air carriers around the world provide a significant share of international tourist trips and are dependent on fluctuations in tourist demand. It has been determined that the understanding of the need to study the degree of interdependence between the tourism and aviation business transforms traditional approaches to the study of tourism and aviation transport. The analyzed functional links between travel companies and airlines allowed asserting the formation of a specialized system, the logistics principles of which will enable people to maximize their mobility potential in the modern globalized world. It has been proved that the development of air transport becomes a decisive factor in the development of tourism, its driving force. For effective joint activities of airlines with tourist enterprises, it is necessary to develop such ways of their interaction that will allow them to function in a coordinated manner within the framework of a single chain of providing tourist services.
The study is devoted to improving the mechanism for the implementation of state youth policy. Youth is the driving force behind the development of society, which requires the participation of all elements of the social system in its formation and direction of the development process along the path of progress. Assessing the experience of management processes in the Russian Federation, it can be argued that state regulation and the solution of youth problems, and especially with regard to graduates of vocational schools and higher educational institutions, is generally imperfect. Therefore, the development of an effective youth policy should be based on the principle most acceptable for today’s youth – partnership in a comprehensive solution to pressing problems of both young people and society as a whole, as well as on equal interaction of the state with all interested social partners and public structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
