  • This study was performed to design a modified Y-View as an imaging method for the Y-View in supine position for patients who requires Y-View imaging for the diagnosis of shoulder impingement syndrome but having trouble for the positioning of patients complaining of shoulder pain. On the result of comparative analysis of the images obtained by changing the lateral-medio degree of X-ray tube into $35^{\circ}$, $40^{\circ}$, and $45^{\circ}$ while patient is in supine position, $40^{\circ}$ of X-ray tube in lateral-medio direction produced the most valuable image for the diagnosis by best describing the shapes of acromion, clavicle space, and coracoacromial arch. Therefore, patients who have difficulty in Y-View position to obtain Y-View image, modified Y-View can be applied as a useful alternative method. By this study, various applications not only in shoulder impingement syndrome but also in diverse omarthralgia diseases are expected.

  • 3D human pose estimation models can be classified into a multi-view model and a single-view model. In general, the multi-view model shows superior pose estimation performance compared to the single-view model. In the case of the single-view model, the improvement of the 3D pose estimation performance requires a large amount of training data. However, it is not easy to obtain annotations for training 3D pose estimation models. To address this problem, we propose a method to generate pseudo ground-truths of multi-view human pose data from a multi-view model and exploit the resultant pseudo ground-truths to train a single-view model. In addition, we propose a multi-view consistency loss function that considers the consistency of poses estimated from multi-view images, showing that the proposed loss helps the effective training of single-view models. Experiments using Human3.6M and MPI-INF-3DHP datasets show that the proposed method is effective for training single-view 3D human pose estimation models.

  • This study is designed to examine characteristics and types of basic landscape design established by 7 local governments in Jeollanam-do and its availability as the index of landscape administration and present a guideline with view landscape plan of local governments. The results of this study are described below. In case of view landscape, while Korean cities have not many historical assets like landmark, they have locational characteristics with mountain or coast in the center or surroundings of downtown. Therefore, since view landscape has many cases of restricting individual property rights as well as having a value as public property of city which makes recognition of sharing city, it is very sensitive problem and establishing guideline of it is needed. But, it was found that view landscape plan of local governments established location of view spot with the nature of relief viewing downtown or coast from high spot. Selection of viewing objects in view plan require deciding an object as the public property of city and big cities require selection from the zone and small cities must select 1~2 spots from the viewpoint of whole downtown. 3~4 view spots of middle and distant views which makes city community centering around the subject of view must be selected through enough discussion and in case of natural landscape, View shaft or visible rays require setting of range that 30% of viewing objects is seen. View spot or viewing objects should be selected over twice as extra spots through public hearing and civil participation as the process.

  • In this paper, an adaptive spatio-temporal predictive coding based on the H.264 is proposed for 3D immersive media encoding, such as 3D image processing, 3DTV, and 3D videoconferencing. First, we propose a spatio-temporal predictive coding using the same view and inter-view images for the two TPPP, IBBP GOP (group of picture) structures 4hat are different from the conventional simulcast method. Second, an 2D inter-view direct mode for the efficient prediction is proposed when the proposed spatio-temporal prediction uses the IBBP structure. The 2D inter-view direct mode is applied when the temporal direct mode in B(hi-Predictive) picture of the H.264 refers to an inter-view image, since the current temporal direct mode in the H.264 standard could no: be applied to the inter-view image. The proposed method is compared to the conventional simulcast method in terms of PSNR (peak signal to noise ratio) for the various 3D test video sequences. The proposed method shows better PSNR results than the conventional simulcast mode.

  • 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.

  • Video-on-demand (VOD) service allows subscribers to view any video whenever they want. With the development of the high speed computer networks, web-based VOD services are available. To support VOD services, charging scheme is necessary. Pay-per-view is an effective charging scheme for VOD services. Pay-per-view allows the subscribers to pay for what they have viewed. Privacy is another important attribute for VOD services. The subscribers may not want to reveal what they have viewed to anyone including the VOD provider. Anonymity makes it complicated to calculate charge for the VOD service. An approach that achieves both anonymity and pay-per-view charge calculation is necessary. In this paper, anonymous web-based VOD service is proposed. The proposed approach also gives pay-per-view capability.

  • This research introduces the architecture of managing products based software. There are many of the architectures for managing products using software instead of manpower. In case of MVC and existing architectures, The architectures transfer redundant data so the architectures cause a problem that unnecessary data moved. This research presents VMDC(View, Model, Dispatcher, Controller) architecture to solve the problem. Dispatcher of VMDC grasps necessary data and reconstructs objects to efficient transferring data. This research shows usecase that designed VMDC(View, Model, Dispatcher, Controller) and demonstrate efficiency of VMDC(View, Model, Dispatcher, Controller) together. after demonstration this research present with next research.

  • This study was inverstigated on that a street view is the important point of the town planning. Until now, the street view has formed with senseless and coarse town planning because of lack of understanding of the street view during the urbanization in the same way and total lack of a consistent plan. On the sight of having a critical mind about the street view, this study was performed to present the analyses of the current problems of the street formation as the vivid directions of development for the future city view of the visual quality and the development of comfort.

  • This study is intended to analyze the characteristics of the preference according to the locations of view points, which are the current criteria for the evaluation of the view. To this end, a total of fifty one test cases according to view point locations were sampled based on the picture data collected in previous studies, and preference assessment was conducted on these cases to identify preference characteristics, where a five-point Lickert-scale evaluation was performed for each test case, and three test cases for each type were comparatively evaluated. It is deemed that the findings from this study may be used to finally derive qualitative assesment scale for the view seen from apartment units.
