불연속선에 의해 생성된 기하학적 착시에서 특징 점들을 추출하는 시각 모델을 제안한다. 기하학적 착시는 선이나 원으로 구성된 것으로서 인간의 정보처리 경로를 통해 발생하는 인지현상중의 하나이다. 이러한 인지 현상은 외부 세계에 존재하는 동일한 강도의 물리적 에너지를 주변자극의 영향 때문에 실제와 다르게 해석하는 현상이다. 착시 그림들로부터 착시 윤곽을 이루는 특징 점을 추출하는 시각 모델을 제안한다. 제안된 인식 모델은 윤곽 추출, 시각 특징 추출, 시각특징 복원, 유도 자극 추출, 이미지 복원 및 이미지 연산 단계로 구성된다. 제안된 모델은 불연속적인 선에 의해 나타나는 착시 윤곽에서 특징 자극들을 추출한다.

스마트폰으로 무선게임을 이용하는 인원이 가입자의 증가로 1,000만 시대에 돌입하였고 2015년까지 연평균 무선게임 증가율을 32%에 달할 것으로 예견된다. 이에 본 연구에서는 착시현상을 이용한 스마트폰 게임을 개발하여 스마트폰 이용자들이 휴식시간에 기분전환으로 본 게임을 사용하도록 개발하였다. 본 개발은 사용자의 감정상태 종류별로 메뉴를 설정해 두어 해당 감정을 전환하는 기능을 추가할 수도 있으며, 여러 사람들과 착시되는 대상을 찾는 놀이로 활용 가능하다. 착시현상을 보는 중 시간을 측정하는 기능을 추가한다면 게임의 기능을 한층 높일 수 있다.

본 연구는 불연속선에 의해 생성된 시각적 착시에서 착시 윤곽의 특징들을 구하는 인식 모델을 제안한다. 착시 윤곽은 일상생환에서 흔히 접하는 현상으로서 외부 세계에 존재하는 동일한 강도의 물리적 에너지를 주변 자극의 영향 때문에 실제와 다르게 해석하는 현상이다. 착시 그림들로부터 착시 윤곽을 이루는 특징 자극을 추출하는 신경회로망 모델을 제안한다. 제안된 인식 모델은 윤곽 추출, 시파 특징 추출, 시파 특징 복원, 유도 자극 추출, 이미지 복원 및 이미지 연산 단계로 구성된다. 제안된 모델은 불연속적인 선에 의해 나타나는 오프셋 격자 윤곽에서 특징 자극들을 추출한다.

시각은 실제와 다른 여러 가지 현상을 일으켜 착시현상을 유발하게 한다. 대부분의 조형 예술은 착시를 포함하고 있고 이것은 시각 예술에 다양하게 적용되며 특히, 인체를 도구로 한 조형 예술인 패션은 미적 욕구를 위한 인체의 시각적 변형을 통하여 한 차원 높은 새로운 시각 예술을 창조하고 있다. (중략)

This paper proposes a neural network model for extracting optical illusions produced by a sequence of discontinuous dot stimuli. The proposed model is based on visual cell's characters founded by visual information processing path. This study approaches on the basis of physiological observation of the perceptual phenomena that some simple ways of discrete dots are perceived as a continuous virtual contour rather than as separate dots. This paper presents the implementation of the optical illusions from discrete dot stimuli that are composed of virtual polygons from 6 to 10 dots. This experimental data are similar to those of Smith & Vos's physiological experiments. The proposed model shows that it can extract continuous illusion contours from discrete dot stimuli successfully.

Objective : The purpose of this study is to evaluate the effect of task-oriented mirror therapy involve visual illusion on upper extremity functions in stroke patients. Method : We divided into two groups that task-oriented mirror therapeutic exercise program include visual illusion and not include. In order to determine the change in upper extremity function, Box & Block Test and Line-bisection Test was evaluated each time period. Result : The result of this study that we found out that all participation's upper extremity function had been improved during the intervention and sustained during baseline regression. Applying mirror therapy program include visual illusion group more improved trend line during the intervention, visual illusion group, it had been shown there are higher difference between visual illusion group and non-visual illusion group in upper extremity functions. Conclusion : It is thoughtful that task-oriented mirror therapy could help for stroke. It might be more effectiveness to apply who have exercise program include visual illusion.

This paper aims to summarize and analyze the optical illusion designs in magazine advertisements. By giving questionnaires that compare print advertisements using the optical illusion design method and traditional print magazine advertisements without adopting the method, the paper performs a quantitative analysis of technical statistics along with a factor analysis of reliability and exploration using IBM SPSS 27.0. when designing through visual illusion expression methods, you can design from the perspective of visual impact and how the information contained in the product is expressed. While making full use of the characteristics of visual illusion, appropriate use of the combination of visual language and overall structure to maximize the brand The effectiveness of information transmission.

The art of dynamic images has experienced three development stages, including experimental films, recording art, and new media image. By introducing all kinds of new materials, new media to the art, and the art of dynamic images has created more freedom for art creation. With the development of digital information technology, dynamic image works have put forward an increasingly high requirement of visual art. The combination of dynamic images and visual illusion can give rise to different forms and expression methods, thus endowing artworks with more vigor. This paper provides an overview by sorting out the lineage and development of dynamic images in the background, as well as understanding the application and performance of contrasted visual illusion. Based on the understanding of the characteristics of visual illusion, we discuss the new characteristics of applying the theory of visual illusion to new media dynamic images in relation to the technical approach of dynamic images. Through the analysis of specific works of Telematic Vision, we search for its reasonable combination and find the appropriate technical means of implementation. We discuss how to use digital multimedia technology and spatial optical illusion to make the design more novel and impactful, and consider how the combination of digital dynamic image technology and visual illusion should be interpreted and applied.

Murakami and Cavanagh (1998a,b, 1999) reported a jitter aftereffect in a static random noise after a period of adaptation to a patch of dynamic random noise. To a account for this phenomenon. they proposed the retinal slip caused by a small eye movements in the unadapted area, which is usually compensated by the visual system to stabilize images but is unsuppressed due to the adaptation. We tested this hypothesis with new experimental method and stimuli that were supposed to nullify or reduce the effect. However. the aftereffect was still observed even under these stimuls conditions More importantly, the perceived aftereffect was rather different from Murakami and Cavanagh's. After adaptation to a counterphase flickering cosine grating, the adjacent unadapted region seems to move away from the observer during the test period instead of jittering in the frontoparallel plane. We proposed a possible explanation for this new phenomenon noting the severe contrast reduction of the adapted region during flickering period. The aftereffect might be due to the flicker-inducing contrast reduction during adaptation that produces different depth planes for the adapted and unadapted region and its restoration during the test period.
