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.

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.

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 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.

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.

Two experiments were conducted to examine how additional dotted lines and peripheral stimulus to the caf$\grave{e}$ wall illusion affect on the degree of perceived tilt (amount of illusion) and confidency of illusionary perception. The experiment 1 tested the effects of adding mortar (solid line) and bright contrast dotted lines to the borderline of 3 layers of blocks, which are consisted of black and white blocks. On the experiment 2, effects of adding peripheral stimulus on caf$\grave{e}$ wall illusion were tested. The results of experiment 1 showed that adding dotted line on the borderline mortar between blocks has additive effects on confidency of illusory perception. However, no effect on perceived amount of illusion was noted. On the other hand according to the results of experiment 2, adding blocks did increase amount, but not confidency of illusory perception. These results imply that the perception of caf$\grave{e}$ wall illusion is related with response of orientation selective neurons.

The artistic idiom of expression in modern poster art make great use of visual illusion. These visual illusions serve carne in sharp relief the idea or concept the artist wishes set forth to the viewer. However we must look at area beyond the psychological impact of visual illusion to the evolutionary history of past and present poster art. The yes of such investigation reveals that the interest in the sub psychological impact of visual illusion is especially deep and reaches for back into the past in the West. Looking at the a of the 15th century in Europe, there is the tradition of drawing that gives the illusion of distance depth, arid substance know as trompe l'oeil, while actually utilizing a flat surface. On needs only look at the works of Arzhibauld, anamolphoses and the surrealism in the works Eschew to realize their influence modern poster art.

A face is the place where individuals can first give their images visually. This chapter presents how 'Visual optical illusion' works in applying makeup and how to differentiate the direction, location and shape of Lip in the aspect of physiognomy. For this study, employed were five types of face shape produced by Photoshop program. The best-matched facial shape was examined through a questionnaire research after applying the optical illusion of Lip to the five types of face shape. The results were revealed to be identical to ones presented in make-up teaching materials. In conclusion, it was found that well-matched shape and size of Lip could make some changes in the facial impression, changing the face shape into oval shape. The facial line can be modified and supplemented by reshaping such facial parts as the Lip, producing well-balanced facial shape. Consequently, make-up was proved to be one of the methods which can be used to create social and psychological effect which can make a favorable facial impression and individuality, natural impression and image making depending on different purposes, taking advantage of optical illusion effect.

The quantity of image frames, the widths of transparent slits, and the black bars on the scanline are the three basic elements of scanimation. Besides, the size of scanimation, the color and contrast of scanimation, and the brightness of scanline, etc, can also influence the optical illusion of scanimation. Based on the recent principle of production of 2D scanimation, and through asking questions, and making corresponding experiment, this research finally gets to the conclusion. Based on the principle of production of 3D scanimation, and through various basic testing, this paper aims to verify how to bring out the best visual effects (optical illusion) of animated illusion scanimation in publications by using the 3D animation in the publications. And the future goal is to study and flexibly use Z-axis space in the scanimation.

본 논문은 이산 점 자극들을 불연속적인 형태로 배치할 때 나타나는 연속성을 인식하기 위한 시스템을 제안한다. 제안된 시스템은 시각 신경계의 특징 추출 과정을 근거로 한다. 일련의 이산점 자극들이 배열의 형태로 주어질 때 이들은 개별 점으로 인식하기보다 어떤 형태를 가진 선이나 윤곽들로 인식된다. 우리는 이산 점 자극의 이러한 연속성 문제를 인식하기 위해 실험에서는 거리가 다른 여러 개의 점들을 일정한 간격을 갖는 형태로 배치한 후 이를 인식하는 시스템을 제시한다. 이산 점 자극에서 연속성을 인식하는 문제는 기초 시파 실험과 관련된 문제로서 일종의 시각적 착시이다. 실험 결과에서는 이산 점 자극에서 연속성을 갖는 윤곽을 획득함으로서 제안된 시스템의 타당성을 확인한다.
