We propose a new building detection and description algorithm for Lidar data and photogrammetric imagery using color segmentation, line segments matching, perceptual grouping. Our algorithm consists of two steps. In the first step, from the initial building regions extracted from Lidar data and the color segmentation results from the photogrammetric imagery, we extract coarse building boundaries based on the Lidar results with split and merge technique from aerial imagery. In the secondstep, we extract precise building boundaries based on coarse building boundaries and edges from aerial imagery using line segments matching and perceptual grouping. The contribution of this algorithm is that color information in photogrammetric imagery is used to complement collapsed building boundaries obtained by Lidar. Moreover, linearity of the edges and construction of closed roof form are used to reflect the characteristic of man-made object. Experimental results on multisensor data demonstrate that the proposed algorithm produces more accurate and reliable results than Lidar sensor.

For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

This study aims to examine the impact of service recovery in building customer loyalty through the mediating role of customer satisfaction and corporate image. This study also aims to examine the reciprocal relationship between customer satisfaction and corporate image in building customer loyalty. This study uses data from 126 consumers who have received recovery for a service failure in five logistics companies which operates in Southeast Sulawesi in Indonesia, namely; JNEs; J&T Express; Pandu Logistics; MEC; and TiKi. Data was collected using a questionnaire which was then distributed to all respondents via google form. The distribution of respondents at each logistics company provider was as follows: 19 respondents were customers of JNEs; 17 respondents were customers of J&T Express; 32 respondents were customers of Pandu Logistics; 21 respondents were customers of MEC; and 37 respondents were customers of TiKi's. The structural model developed in this study was tested using Partial Least Squared (PLS) method. The research found that service recovery has a direct effect on customer satisfaction and corporate image as positive and significant. Customer satisfaction and corporate image have a reciprocal relationship which then roles in building customer loyalty. Service recovery has an indirect effect on customer loyalty through the mediating role of customer satisfaction and corporate image.

With the increasing demands of 3D spatial information in urban environment, the importance of point clouds generation techniques have been increased. In particular, for as-built BIM, the point clouds with the high accuracy and density is required to describe the detail information of building components. Since the terrestrial LiDAR has high performance in terms of accuracy and point density, it has been widely used for as-built 3D modelling. However, the high cost of devices is obstacle for general uses, and the image-based 3D reconstruction technique is being a new attraction as an alternative solution. This paper compares the image-based 3D reconstruction technique and the terrestrial LiDAR in point of establishing the as-built BIM of outdoor structures. The point clouds generated from the image-based 3D reconstruction technique could roughly present the 3D shape of a building, but could not precisely express detail information, such as windows, doors and a roof of building. There were 13.2~28.9 cm of RMSE between the terrestrial LiDAR scanning data and the point clouds, which generated from smartphone and DSLR camera images. In conclusion, the results demonstrate that the image-based 3D reconstruction can be used in drawing building footprint and wireframe, and the terrestrial LiDAR is suitable for detail 3D outdoor modeling.

Recently the extraction of building height information has been investigated using remotely sensed image and digital maps. In this study, based on the digital photogrammetry principle and mono imagery method the building height information can be extracted by using relationship between ground coordinates and image coordinates. To evaluate the result the comparison was done with building height from 1:5000 aerial photo. The experiment shows that extraction of building height could be performed using IKONOS single imagery and digital map and it is proved that the building height could be reconstructed within some extent.

In order to sustain competitive advantage through strategic product differentiation in global market, this research aims to establishment of strategic design conditions for domestic manufacturing firms through the means of product image alignment and positioning, using visual character of product as the foundation for establishing corporate image. Case studies on how globally successful multinational companies manage design strategy and corporate culture uniformly for coherent product image management are reviewed. To establish product image alignment methodology for manufacturing firms, the criteria for product image positioning and aligned product image development process are developed in three stages. First, in image positioning stage, it is important to set the direction for corporate image and design strategy by identifying consumer needs through market trends analysis and forecasting as well as comparative positioning of the analysis results of the firms's own corporate image and that of the competitor's. Second, in awareness building stage, before building the product image alignment, firm-wide shared awareness of differentiated corporate and product image, establishment of designer's role as the consolidated manager of product image, sharing form language, and building the infrastructure for defining form information should be preceded. Third, in managing the aligned product image stage, the condition for setting up image information management guideline, management of decision making process for arriving at logical decisions on product form, development of guideline for increasing efficiency and its evaluation system, and co-development of related design should be induced. Further research on the product image alignment with corporate image should be conducted through various empirical studies on image and form, building an information system of related design language, and continuous assessment and management of applied solutions.

With the shift of consumer’s spending behaviors further into emotionally-driven purchases, the role of brand is becoming even more important, which in turn, expands design’s role in the brand image strategy. The contact point between the consumers and the brand is the primary channel for building strong brand image through experience. Therefore, it is critical to comprehensively plan and manage the consumer contact point for any brand. Given the changing market conditions, the objective of this study is to define and structure an integrated design development and management system for building successful brand image. In order to do so, the research analyzed the characters of brand image, the conditions for consumer experience and the roles of emotion. The analysis into the correlation between images and emotion process model yields three natures of an image. The image 1) is based on empirical decisions, 2) expresses and conveys emotional aspects and 3) builds mental values through a sense of sympathy. Through case studies of successful designs that meet all three characteristics, the roles of a brand icon in building strong brand image and the needs for integrated design approach for implementation are defined. The methods for integrated design include 1) providing a focal point through brand image positioning, 2) utilizing visual themes based on brand image plot, 3) building a Total Identity Program to holistically manage brand images and 4) developing brand icons for brand image reinforcement.
