  • This paper proposes a novel approach for the model-based pose matching of a human body using Active Shape Models. To improve the processing time of model creation and registration, we use a skeleton-type model instead of the conventional silhouette-based models. The skeleton model defines feature information that is used to match the human pose. Images used to make the model are for 600 human bodies, and the model has 17 landmarks which indicate the body junction and key features of a human pose. When applying primary Active Shape Models to the skeleton-type model in the matching process, a problem may occur in the proximal joints of the arm and leg due to the color variations on a human body and the insufficient information for the fore-rear directions of profile normals. This problem is solved by using the background subtraction information of a body region in the input image and adding a 4-directions feature of the profile normal in the proximal parts of the arm and leg. In the matching process, the maximum iteration is less than 30 times. As a result, the execution time is quite fast, and was observed to be less than 0.03 sec in an experiment.

  • This paper introduces an appearance-based facial expression recognition method using ASM landmarks which is used to acquire a detailed face region. In particular, EHMM-based algorithm and SVM classifier with histogram feature are employed to appearance-based facial expression recognition, and performance evaluation of proposed method was performed with CK and JAFFE facial expression database. In addition, performance comparison was achieved through comparison with distance-based face normalization method and a geometric feature-based facial expression approach which employed geometrical features of ASM landmarks and SVM algorithm. As a result, the proposed method using ASM-based face normalization showed performance improvements of 6.39% and 7.98% compared to previous distance-based face normalization method for CK database and JAFFE database, respectively. Also, the proposed method showed higher performance compared to geometric feature-based facial expression approach, and we confirmed an effectiveness of proposed method.

  • This project provides designs for renewal of the surrounding environment related to old fountains typically located in cities. In many cities, the fountain element has bee located with a strategic position in the city. Located in the central area of Cheongju, the Sajik Fountain Fountain has significant position in the local city. However, due to changes in the surrounding area and the old-fashioned form of the fountain, it has not contributed substantially to the cityscape. Including the historical Seomoon Bridge and Moosim-Cheon(stream) as Wooam-San(mountain) setting, the surrounding environment of our planning site appear to be a locally important place. In respect to building with a broad function, landscape designers focused on the reconsideration of symbolization as landmark, of the image of Cheongju city, of recognition by removing the horizontal line and of the substantial civil´s use rate. Achieved by working with a sculptor, a new function, the main facility, is managed sculpturally and imaged in a drop of water representing clear, fresh Cheongju city. This plan introduces the image of Wooam-San, Moosim-Cheon(stream), Sangdang-SanSung(A mountain fortress) and elicit a sense of peace, symbolic of Cheongju. The significance of this project is that as the current cities are increasingly developed, small areas left alone in city are reconsidered and offered to the public as efficient, resting and active outdoor space.

  • A 3D face shape derived from 2D images may be useful in many applications, such as face recognition, face synthesis and human computer interaction. To do this, we develop a fast 3D Active Appearance Model (3D-AAM) method using depth estimation. The training images include specific 3D face poses which are extremely different from one another. The landmark's depth information of landmarks is estimated from the training image sequence by using the approximated Jacobian matrix. It is added at the test phase to deal with the 3D pose variations of the input face. Our experimental results show that the proposed method can efficiently fit the face shape, including the variations of facial expressions and 3D pose variations, better than the typical AAM, and can estimate accurate 3D face shape from images.

  • On October 31, 2013, the Singapore Court of Appeals handed down a landmark decision in the case of PT First Media TBK v Astro Nusantara International and Others [2013] SGCA 57. The case arose out of an arbitration in Singapore involving the Malaysian conglomerate Astro and the Indonesian conglomerate Lippo, which culminated in a USD 250 million award in favor of Astro. The final award was given to three Astro subsidiaries who were not parties to the arbitration agreement, but who were joined in the arbitration pursuant to an application by Astro. Lippo then applied to the Singapore High Court to set aside the enforcement orders. The Court of Appeals, however, reversed the High Court's decision, and found that Astro was only entitled to enforce the awards. Also, the Court of Appeals undertook a detailed analysis of the use of active and passive remedies to defeat an arbitral award at the seat and the place of enforcement, respectively. It also touches on the innovation of forced joinders of third parties in arbitrations, which have garnered significant interest in the arbitration community. This decision is therefore expected to have a significant impact on the practice of international arbitration, including in relation to how awards can be enforced or defeated, as the case may be.

  • Statistical models of shape variability based on active shape models (ASMs) have been successfully utilized to perform segmentation and recognition tasks in two-dimensional (2D) images. Three-dimensional (3D) model-based approaches are more promising than 2D approaches since they can bring in more realistic shape constraints for recognizing and delineating the object boundary. For 3D model-based approaches, however, building the 3D shape model from a training set of segmented instances of an object is a major challenge and currently it remains an open problem in building the 3D shape model, one essential step is to generate a point distribution model (PDM). Corresponding landmarks must be selected in all1 training shapes for generating PDM, and manual determination of landmark correspondences is very time-consuming, tedious, and error-prone. In this paper, we propose a novel automatic method for generating 3D statistical shape models. Given a set of training 3D shapes, we generate a 3D model by 1) building the mean shape fro]n the distance transform of the training shapes, 2) utilizing a tetrahedron method for automatically selecting landmarks on the mean shape, and 3) subsequently propagating these landmarks to each training shape via a distance labeling method. In this paper, we investigate the accuracy and compactness of the 3D model for the human liver built from 50 segmented individual CT data sets. The proposed method is very general without such assumptions and can be applied to other data sets.

  • Currently, image of floating architecture has been positively improved based on the normalization of a domestic representative floating building 'Some Sevit'. Features of the floating architecture are as follows: special experience (29.9%)> landmark (27.6%)> enjoyment of marine culture (21.5%)> center for tourism and regional development (16.0%)> eco-friendly space solving global warming (4.8%). Floating building has a distinctive image and at the same time offers a unique spatial experience to the public. Therefore, space design marketing of floating building is a communication process to exchange its spatial identity and image between the local government and the public, the corporation and customers. It is essential for the effective space design marketing that the spatial demands should be reflected into its program such as commercial, cultural and marina facilities. The unification of project leader and operator is also important. The transformed conditions would help the construction market to be active in the future.

  • The utilization of coatings composed of bio-based materials in the processing and preservation of meat presents an environmentally conscious, secure, cost-effective, and superior method for prolonging the storage life of meat while also preserving its nutritional value. In this study, changes in physical, chemical, and microbiological characteristics of freshly cut beef coated with distilled water (control) and keratin-starch composites (K-S) functionalized with 0.0-, 0.2-, 0.6-, and 1.0-mL avocado peel polyphenolic-rich extract (APPPE) kept at 4℃ for 12 days were evaluated periodically at 3-day interval using standard techniques. Keratin was extracted from waste feathers, while starch was obtained from ginger rhizomes. Following a 12-day storage period, beef coated with APPPE-enriched K-S composites exhibited a significant (p<0.05) improvement in shelf life by minimizing deteriorative changes in pH and color (as determined by metmyoglobin level) in addition to inhibiting oxidative changes in lipids (as determined by TBARS level) and proteins (protein carbonyl level) in comparison to control and K-S composite without APPPE. Furthermore, microbial growth was significantly (p<0.05) suppressed in meat coated with K-S composite functionalized with APE at 0.6 and 1.0 mL compared to the control. The study suggested that APPPE-enriched K-S composite could offer an eco-friendly and safe food preservation technique for fresh meat.
