The design trend is changed with the times. The design trend of recent 21 century is eco-friendly design. The optical illusion design is a new trend of digital convergence era. In this study, optical illusion patterns were designed for furniture with eco-friendly UV-curable resin. The micro-patterns of optical illusion design were fabricated with the micro-mold which was mastered using a semiconductor micro-fabrication process by photolithography technique. The micro-patterns of optical illusion design were manufactured on PET film with a roll-to-roll process using a UV-curable resin. The manufactured PET film of optical illusion micro-pattern exhibits hologram effect, optical illusion effect, and texture of metal with the backside digital printing of metal tone. The furniture of new design concept so-called emotional furniture was manufactured with the various optical illusion design patterns. The optical illusion design patterns by UV mold prospect a new trend of interior design materials.

Patterns have their own shapes and characteristics as a symbol in accordance with in what environment they are like a language. Especially our ancestor had wished present values as like riches and honors, longevity and health, love and happiness through all kinds of patterns of animals, plants, the sun, the moon, cloud, water and mountain, and expressed an aesthetic consciousness. Pattern design is important in fashion but it is insufficient in terms of the development of modern patterns based on Korean traditional patterns. Therefore, We need to create new senses and thoughts through the understanding and re-analysis about Korean traditional costume and a study on optical patterns could give an extreme effect without any changes of silhouette. Especially, Emilio Pucci and Missoni have been developing a variety of Pattern designs even though there are different tendencies each other. Consequently it could be a good chance to show Korean images and originality that develope the various textile patterns with applying to Korean traditional patterns based on an analysis of their works.

군중의 이상행동을 검출하는 것은 군중 모니터링, 보안 및 CRM 시스템의 관점에서 중요한 요소 중의 하나이다. 기존의 방법은 대다수가 옵티컬플로우를 기반으로한 검출방법으로 객체가 움직이지 않는 경우에는 객체로 인식할 수 없는 문제점이 생긴다. 또한, 많은 데이터량을 처리하기 때문에 실시간성이 보장되지 않는다는 단점이 있다. 이를 극복하기 위해서, 본 논문에서는 특징점 맵 보정과 분포분석을 통한 군중의 밀집과 대피하는 현상을 검출하는 방법을 제안한다. 먼저, 군중에서 옵티컬플로우 기반으로 움직이는 FAST 특징점을 추출하고 추출된 특징점의 분포에따라 특징점맵을 복원한다. 복원된 특징점 맵과 특징점의 분포에 기반하여 군중의 이상정도를 결정하게 된다. PETS2009 데이터베이스를 사용하여 결과를 측정하였다.

Vision is the most important sense of the five senses in our body. This represents that an eye is for the mysterious organ playing the essential role in our body. Alain Mikli known as a famous spectacle designer in France said that glasses exists for seeing and for being seen. This saying is one of the philosophically well-organized definition of the most fundamental function of eye-glasses described in and out of itself. Today, in the world, there are a number of works of glasses design and lots of glasses designers are designing hard in order to convey the goods with the best value and philosophy to customers. They work for the goal that glasses is used as seeing and try to give customers satisfaction and enjoyment of it. And they think that glasses should play the role of the interface. At this point, we need to catch hold of the interface of glasses. That means that glasses has to have the communication between eyes and objects and be the mediation of the connection between the image of oneself and that of one by others. For the character of the interface of glasses, glasses designers should plan and investigate this character at the being of design. This study of optical art has been researched for the necessary and sufficient condition between consumers and products.

The temporal super resolution is a method for increasing the frame rate. Electro-optical sensors are used in various surveillance and reconnaissance weapons systems, and the spatial resolution and temporal resolution of the required electro-optical sensors vary according to the performance requirement of each weapon system. Because most image sensors capture images at 30~60 frames/second, it is necessary to increase the frame rate when the target moves and changes rapidly. This paper proposes a method to increase the frame rate using color channel extrapolation. Using a DMD, one frame of a general camera was adjusted to have different consecutive exposure times for each channel, and the captured image was converted to a single channel image with an increased frame rate. Using the optical flow method, a virtual channel image was generated for each channel, and a single channel image with an increased frame rate was converted to a color channel image. The performance of the proposed temporal super resolution method was confirmed by the simulation.
