Management practices and ordinances for urban scenic view protection are varied by cities because they have their distinctive nature and social environment. Therefore landscape management methods for urban scenic views are generally varied by the characteristics of city landscape and ordinance. This case study for scenic view protection practices in U.S.A. is very meaningful and appropriate because cities initiate a plan and/or an ordinance to manage urban scenic view in Korea. Urban scenic view protection methods were analyzed based on followings: 1) how to select scenic view resources and define spatial areas for preserving them, 2) how to control building height, open view corridor and guide landscaping and 3) how to carry out view protection methods and organize them in laws or ordinances. Findings of this study will be applied usefully in the development of urban scenic view protection methods in Korea.

Recently, user-created video shows high increasing in production and consumption. Among these, videos records an identical subject in limited space with multi-view are coming out. Occurring main reason of this kind of video is popularization of portable camera and mobile web environment. Multi-view has studied in visually representation technique fields for point of view. Definition of multi-view has been expanded and applied to various contents authoring lately. To make user-created videos into multi-view contents can be a kind of suggestion as a user experience for new form of video consumption. In this paper, we show the possibility to make user-created videos into multi-view video content through analyzing multi-view video contents even there exist attribute differentiations. To understanding definition and attribution of multi-view classified and analyzed existing multi-view contents. To solve time axis arranging problem occurred in multi-view processing proposed audio matching method. Audio matching method organize feature extracting and comparing. To extract features is proposed MFCC that is most universally used. Comparing is proposed n by n. We proposed multi-view video contents that can consume arranged user-created video by user selection.

Free viewpoint TV can provide multi-angle view point images for viewer needs. In the real world, But all angle view point images can not be captured by camera. Only a few any angle view point images are captured by each camera. Group of the captured images is called multi-view image. Therefore free viewpoint TV wants to production of virtual sub angle view point images form captured any angle view point images. Interpolation methods are known of this problem general solution. To product interpolated view point image of correct angle need to depth image of multi-view image. Unfortunately, multi-view video including depth image is necessary to develop a new compression encoding technique for storage and transmission because of a huge amount of data. Layered depth image is an efficient representation method of multi-view video data. This method makes a data structure that is synthesis of multi-view color and depth image. This paper proposed enhanced compression method using layered depth image representation and H.264/AVC video coding technology. In experimental results, confirmed high compression performance and good quality reconstructed image.

This article focuses on perspectives of game in terms of interactivity between game texts and players. There are many points of view which have been discussed, such as first person point of view, third person point of view, top-down point of view, side-view point of view, quarter-view point of view, and isometric point of view, but they are too insufficient to fully explain the perspectives of game from the viewpoint of the interactivity. This paper examines the function of player and game manufacturer as implied authors on interactive point of view, and discusses the perspectives of game through a sense of distance between players as implied author and player characters.

Human detection techniques in outdoor scenes have been studied for a long time to watch suspicious movements or to keep someone from danger. However there are few methods of human detection in overhead or near-field view scenes, while lots of human detection methods in far-field view scenes have been developed. In this paper, a set of five features useful for human detection in overhead view scenes and another set of four useful features in near-field view scenes are suggested. Eight feature-candidates are first extracted by analyzing geometrically varying characteristics of moving objects in samples of video sequences. Then highly contributed features for each view scene to classifying human from other moving objects are selected among them by using a neural network learning technique. Through experiments with hundreds of moving objects, we found that each set of features is very useful for human detection and classification accuracy for overhead view and near-field view scenes was over 90%. The suggested sets of features can be used effectively in a PTZ camera based surveillance system where both the overhead and near-field view scenes appear.

The purpose of Environmental subject in the Korean school is pretty much similar to that of international organization. Because it doesn't apply the characteristics of School Education to environmental education, this school environmental education purpose needs to be discussed. The purpose of this study is to establish the reasonable purpose of school environmental education by analyzing the educational views. This study have been done through review of research literature, which usually includes references and papers on environmental education, school environmental education, educational point of view, educational purpose. It analyzed three kinds of views on education: technological view on education, initiation view on education, socialization view on education. The results are as follows: The purpose of school environmental education from technological view on education is environmental education activity itself that educates students to put the environmental preservation value into action. Initiation view on education aims at school environmental education as activities that instruct students on intellectual ability in order to develop a comprehensive view of intelligence. The purpose of environmental education in school on the basis of socialization view on education focuses on activities that authoritative teachers transmit the social value of environmental preservation to students in school.

In this paper, we propose Multi-view CGH Making System using method of generation of virtual view-point depth image. We acquire reliable depth image using TOF depth camera. We extract parameters of reference-view cameras. Once the position of camera of virtual view-point is defined, select optimal reference-view cameras considering position of it and distance between it and virtual view-point camera. Setting a reference-view camera whose position is reverse of primary reference-view camera as sub reference-view, we generate depth image of virtual view-point. And we compensate occlusion boundaries of virtual view-point depth image using depth image of sub reference-view. In this step, remaining hole boundaries are compensated with minimum values of neighborhood. And then, we generate final depth image of virtual view-point. Finally, using result of depth image from these steps, we generate CGH. The experimental results show that the proposed algorithm performs much better than conventional algorithms.

Recently, many researches have been focused on multi-view video applications and services such as wireless video surveillance networks, wireless video sensor networks and wireless mobile video. In multi-view video signal processing, to exploit the strong correlation between images acquired by different cameras plays great role in developing a core technique of multi-view video coding. This paper proposes an adaptive multi-view video interpolation technique which is applicable for multi-view distributed video coding without requiring any cooperation amongst the cameras. The proposed algorithm estimates the non-linear moving blocks and employs disparity compensated view prediction, and then fills in the unreliable blocks. Through computer simulations, it is shown that the proposed method outperforms the conventional methods.
