In this paper, a novel method is proposed using color and pattern information for recognizing some emotions included in a fertile. Here we use 10 Kobayashi emotion to represent emotions. - { romantic, clear, natural, casual, elegant chic, dynamic, classic, dandy, modem } The proposed system is composed of feature extraction and classification. To transform the subjective emotions as physical visual features, we extract representative colors and Patterns from textile. Here, the representative color prototypes are extracted by color quantization method, and patterns exacted by wavelet transform followed by statistical analysis. These exacted features are given as input to the neural network (NN)-based classifiers, which decides whether or not a textile had the corresponding emotion. When assessing the effectiveness of the proposed system with 389 textiles collected from various application domains such as interior, fashion, and artificial ones. The results showed that the proposed method has the precision of 100% and the recall of 99%, thereby it can be used in various textile industries.

The requirement of Digital Culture Content(Movie, Music, Animation, Digital TV, Exhibition and etc.) is increasing so variety and quantity of content is also increasing. The Movie what majority of the digital Content is developing of technology and data. In the result, the efficient retrieval service has required and user want to use a recommendation engine and semantic retrieval methods through the recommendation system. Therefore, this paper will suggest analysing trait element of digital content data, building of retrieval technology, analysing and retrieval technology base on KANSEI vocabulary and etc. For the these, we made a extraction technology of trait element based on semantics and KANSEI processing algorithm based on color information.

작금의 현대 사회는 바쁜 일상 속 부모들의 관심이 부족한 자녀들에 대한 심리적 안정과 환경 적응력을 위한 색채심리치료의 필요성이 급증하고 있다. 이에 우리는 아동의 그림 등으로 아동의 감성상태를 파악하여야 한다. 현재 진행 중인 감성의 실증적 연구는 크게 심리학적 관점과 공학적 관점에서 이루어지고 있다. 심리학분야에서 이해하고 있는 감성은 감정에 가깝다고 할 수 있고, 한편 공학적 관점에서 이해되는 감성은 '외부의 물리적 자극에 의한 감각, 지각으로부터 인간의 내부에 야기되는 고도의 심리적 체험'으로 정의할 수 있다. 본 논문에서는 색채 이미지 공간에서의 단색, 배색의 정보를 활용하여 색채조화를 식별하고, 아동의 그림에서의 심리를 추출해내는 시스템을 제공한다. 우선 색채 이미지공간을 기반으로 감성 데이터베이스를 구축한다. 이후에 영상을 K-Means알고리즘을 이용해 클러스터링 하여 방대한 컬러 값들을 그룹화 시킨 후에 데이터베이스와 매칭을 시켜 감성을 추출해 내고, 아동의 그림에서의 컬러 분포도를 이용하여 아동색채심리를 알아본다.

This paper construct the sensibility database by extracting sensibility of 28 colors based on 12 color wheel. And, after the large color values are grouped by clustering of input image using k-mean algorithm, sensibility was extracted by matching with color and database. Also, we see the color sensible psychology of child using color distribution of children in painting.

본 논문에서는 감성을 기반으로 텍스타일 영상을 자동으로 분류할 수 있는 시스템을 제안한다. 이 때, 사용된 감성 그룹은 고바야시의 10가지 감성 키워드 - {romantic, clear, natural, casual, elegant, chic, dynamic, classic, dandy, modern} - 를 이용한다. 제안된 시스템은 특징 추출과 분류로 구성된다. 특징 추출 단계에서는 텍스타일을 구성하는 대표 컬러를 추출하기 위해서 양자화 기법을 이용하고, 패턴정보를 표현하기 위해서는 웨이블릿 변환 후의 통계적인 정보를 이용한다. 신경망 기반의 분류기는 추출된 특징들을 입력으로 받아 입력 텍스타일 영상을 분류한다. 제안된 감성인식 방법의 효율성을 증명하기 위해서 220장의 텍스타일 영상에서 실험한 결과 제안된 방법은 99%의 정확도를 보였다. 이러한 실험 결과는 제안된 방법이 다양한 텍스타일 영상에 대해 일반화되어 사용될 수 있음을 보여주었다.

This paper proposes a new strategy of emotion-based music visualization. Emotional LED lighting control system is suggested to help audiences enhance the musical experience. In the system, emotion in music is recognized by a proposed algorithm using a dimensional approach. The algorithm used a method of music emotion variation detection to overcome some weaknesses of Thayer's model in detecting emotion in a one-second music segment. In addition, IRI color model is combined with Thayer's model to determine LED light colors corresponding to 36 different music emotions. They are represented on LED lighting control system through colors and animations. The accuracy of music emotion visualization achieved to over 60%.

제스처 인식은 직관적일 뿐 아니라, 몇 가지의 기본 구성요소에 의하여 코드화(code)가 용이하여, 인간과 컴퓨터의 상호작용(HCI, Human-Computer Interaction)에 있어서 폭넓게 사용되고 있다. 본 논문에서는 손의 모양이나 크기와 같은 개인차 및 조명의 변화나 배율과 같은 입력환경의 영향을 최소화하여, 특별한 초기화 과정이나 모델의 준비과정 없이도 제스처를 인식할 수 있고, 적은 계산량으로 실시간 인식이 가능한 제스처 인식 시스템의 개발을 목표로 한다. 본 논문에서는 손에 부착하는 센서나 마커 없이, CCD 카메라에 의하여 입력된 컬러영상에서, 컬러정보 및 동작정보를 이용하여 손영역을 추출하고, 추출된 손의 경계선 정보를 이용하여 경계선-중심 거리 함수를 생성했다. 그리고, 손가락의 끝 부분에서는 경계선-중심 거리가 극대점을 이룬다는 원리를 이용하여 생성된 함수의 주파수를 분석하여 극대점을 구함으로써 각각의 손가락 끝 위치를 찾고, 손의 자세를 인식하여 제스처를 인식했다. 또한 본 논문에서 제안된 제스처 인식 방법은 PC상에서 구현되어 그 유용성과 실효성이 증명되었다.

The final aim of the present study is to build a system of converting a color image into musical elements based on a synesthetic perception, emulating human synesthetic skills, which make it possible to associate a color image with a specific sound. This can be done on the basis of the similarities between physical frequency information of both light and sound. As a first step, an input true color image is converted into hue, saturation, and intensity domains based on a color model conversion theory. In the next step, musical elements including note, octave, loudness, and duration are extracted from each domain of the HSI color model. A fundamental frequency (F0) is then extracted from both hue and intensity histograms. The loudness and duration are extracted from both intensity and saturation histograms, respectively. In experiments, the proposed system on the conversion of a color image into musical elements was implemented using standard C and Microsoft Visual C++(ver. 6.0). Through the proposed system, the extracted musical elements were synthesized to finally generate a sound source in a WAV file format. The simulation results revealed that the musical elements, which were extracted from an input RGB color image, reflected in its output sound signals.

In modern society, the necessity of Color and Psychology Therapy is increasing for psychologically calm children who are less taken care by their parents in busy daily life, and helping them adapt to the environment. Therefore, we need to understand sensitivity status of children with paintings that they draw. Currently, most of empirical studies on their sensitivities are based on psychological and engineering perspectives. This study was designed to provide a system to extract psychological status of children from their pictures by distinguishing harmony of colors using information of solid colors and arrangement of colors in the image space. For achieving this research purpose, first of all, sensitivity database was constructed based on the image space of colors. Then, using the K-Means algorithm, the image was clustered and a wide amount of color values were divided into groups. After that, children's sensitivities were extracted by matching groups of color values with database, and color psychological status of children was observed using the color distribution chart in their paintings.

This study aims for building an application system of converting sound into color image based on synesthetic perception. As the major features of input sound, both scale and octave elements extracted from F0(fundamental frequency) were converted into both hue and intensity elements of HSI color model, respectively. In this paper, we used the fixed saturation value as 0.5. On the basis of color model conversion theory, the HSI color model was then converted into the RGB model, so that a color image of the BMP format was finally created. In experiments, the basic system was implemented on both software and hardware(TMS320C6713 DSP) platforms based on the proposed sound-color image conversion method. The results revealed that diverse color images with different hues and intensities were created depending on scales and octaves extracted from the F0 of input sound signals. The outputs on the hardware platform were also identical to those on the software platform.
