This study investigated how consumers perceive brand image, the consistency between the images of parent brands and extended brands, the consistency of their advertising images, the differences between brand image and advertising image, and how consumers' brand attitudes change based on those differences. An online survey was administered to women in their 20s and 30s who often use cosmetics and are interested in brands. The brands considered in this research were Chanel, Dior, Armani, and Anna Sui, which have extended brands in the clothing and cosmetics areas. In terms of consumers' perception of brand image, it was found that clothing and cosmetic brands were perceived similarly. In addition, significant differences were found in consumers' preferences and purchase intentions of clothing and cosmetic brands, and those whose perceptions of brand image did not change or increased after looking at advertising images had more positive brand attitudes than the group of people who had higher perception of brand image before looking at advertising images. Therefore, in terms of brand extension, it was revealed that the image of a parent brand affected an extended brand, and that the higher was consumers' recognition of brand image through advertising, the more positive was their attitude toward the brand.

In this paper, we propose an improved image encryption and decryption method using a phase-encoded virtual image and interference. An original image is simply decrypted by interfering a reference wave with the wave passing through a decrypting key and the encrypted image, where every image has grey level. The proposed encryption is performed by the multiplication of an encrypting key and a phase-encoded virtual image which dose not contain any information for the original image. Therefore even if unauthorized people analyze the encrypted image, they cannot reconstruct the original image. Also grey image encryption can improve the encryption level compared to binary image encryption. Computer simulation and optical experiments confirmed that the proposed technique is a simple for optical encryption.

One hand shopping center provides a public space for people, the other hand it is a place for commercial purpose. Although it gives an entertainment, eating and shopping places to people nowaday, owners and tenants aim to make profit from it. According to this demand designers should plan a shopping center for a comfortable place for eating, shopping and playing and they make shops and retails to increase sales by exposing those to more people at the same time. For successful shopping center architects are requested an approach with commercial strategy that shopping center raises exposure of retails and makes stay costumers longer and visit more frequently. Recently space is regarded as a mean of marketing, so-called "place marketing", because it can influence on brand image and improves the image of product. Therefore, it need to be approached with commercial consideration. Analyzing the armature this study will take a look at spatial strategies in shopping centers which especially the Jerde Partnership, one of influential firms on commercial space, designed. And it will examine how spatial strategies can be applied to commercial strategies in relation to customer information process(exposure-attention-interest-comprehension-memory) which marketers are using in advertisement for marketing and what kind of role spatial strategies can be. This study is to be basic considerations when a shopping center project will be planned.

Assault and violence in the elevator is a crime that occurs most frequently. In particular, these days, is a phenomenon that occurs frequently, knowing that there is a CCTV camera. In this paper, we extract the phenomena of contact between people in the elevator. Many people ride the elevator does not cause these symptoms. However, this crime occurs when fewer people ride the elevator. Extraction method of contact is seeking the skeleton of binary image and extracts the contact status of each skeleton. Therefore, immediately detecting the violence and assaults that occur in the elevator and to notify the security office of the building.

There are many visual enhancement devices for people with low vision. However, almost conventional devices have been simple magnifying and high cost. The symptoms of people with low vision are very variety. It needs to control of image magnifying, brightness, and contrast to improve the visuality. We developed a portable microdisplay driver and device for visual enhancement. This device based on our suggested four methods such as image magnifying, specific color control, BLU brightness control, and visual axis control using a prism. The basic clinical experiments of the proposed Head Mounted Visual Enhancement Device (HMVED) have been performed. The results show beneficiary effects compared with conventional devices, and improve the life quality on people with low vision on account of low weight, low cost, and easy portability.

We propose a face recognition and notification system that can transform visual face information into tactile signals in order to help visually impaired people. The proposed system consists of a glasses type camera, a mobile computer and an electronic cane. The glasses type camera captures the frontal view of the user, and sends this image to mobile computer. The mobile computer starts to search for human's face in the image when obstacles are detected by ultrasonic sensors. In a case that human's face is detected, the mobile computer identifies detected face. At this time, Adaboost and compressive sensing are used as a detector and a classifier, respectively. After the identification procedures of the detected face, the identified face information is sent to controller attached to a cane using a Bluetooth communication. The controller generates motor control signals using Pulse Width Modulation (PWM) according to the recognized face labels. The vibration motor generates vibration patterns to inform the visually impaired person of the face recognition result. The experimental results of face recognition and notification system show that proposed system is helpful for visually impaired people by providing person identification results in front of him/her.

Future science fiction science film science fiction film can easily see the appearance of the futuristic inquiry. Even if a person does not open the door by force, the door is opened and closed by the system. Even now, such a door can be found easily. However, in the past, people who have not been able to perceive people have been used only in public places such as department stores and marts, where there are many people who are inundated. However, a lot of researches are being done now, and we are pursuing convenience in everyday life by integrating the image processing technology that has been developed and developed many times, by implementing the automatic door which is not infringed by the personal life and is impossible for anyone to access.

The traditional media ecosystem is facing major changes with the expansion of over-the-top (OTT) services. While the percentage of people cutting the cord has already exceeded the percentage of people subscribing to pay TV services in the United States, due to the unique characteristics of the Korean market, it is uncertain whether the cord-cutting trend will have an impact on the Korean media industry despite of the advantages of OTT services. Accordingly, this study has directly determined the beneficial and sacrificial factors of switching to OTT services, as well as the personal and external influences behind the Korean OTT service users' intention to switch. To achieve this, the Value-based Adoption Model (VAM) was used to measure the benefits of OTT services with regards to their content and systems, as well as measure the financial and procedural switching costs of cord-cutting; further, personal innovativeness and consumers' social image were added as external variables. The results of this study showed that consumers take the content and system quality of OTT services and procedural switching costs and into consideration, and that their intention to switch was based on social image. These results could serve as data for consumer analysis regarding the expansion of OTT services into the Korean media industry, and also provide the strategic basis for preparing for sudden changes that may occur in the media ecosystem due to cord-cutting.

This paper proposes a new re-coloring method for the people with the red-green color vision deficiency (CVD). These people have difficulty in discriminating the red and green colors since they abnormally perceive the hue and luminance value of the colors. We introduce a color transformation that adjusts the hue and luminance value in HSV color space. The color transformation is determined according to the severity of CVD. Our aim is to maintain the color differences in original image while maintaining the recolored image to be natural to the people with normal color vision. Experimental results show that the proposed method can yield more comprehensible images for the people with red-green CVD while maintaining the naturalness of the recolored images.
