The image segmentation is the most important operation in an image processing system. It is located at the joint between the processing and analysis of the images. Unsupervised segmentation aims to automatically separate the image into natural clusters. However, because of its complexity several methods have been proposed, specifically methods of optimization. In our work we are interested to the technique SFLA (Shuffled Frog-Leaping Algorithm). It's a memetic meta-heuristic algorithm that is based on frog populations in nature searching for food. This paper proposes a new approach of unsupervised image segmentation based on SFLA method. It is implemented and applied to different types of images. To validate the performances of our approach, we performed experiments which were compared to the method of K-means.

This paper surveys the meaning of the pen name ′Yi Sang(李箱)′ in the light of the arbitariness of language and the relationship among names, observing in three ways how the images of ′Sang′ (Box) appear differently in his works. In Particular, we look into (1) the relationship between a box and its inner boxes, (2) the divisional relationship in the box, and (3) the relationship between the box and an outer box. In Yi Sang′s work, image (1) gives shape to the relationship between the writer himself and his ancestors who are responsible for his present existence. Image (2) gives shape to two internally divided Yi Sangs, and is symbolized as a mirror that reflects two selves. Image (3) gives shape to a relationship between himself in the closed world and other people and/or a bigger outside world. All these symbolic relationships are fully represented in his work "Nalgae" (The Wing)". What is interesting is that Yi Sang has already employed these box images in his earlier poetry "Geonchuk-muhan-yukmyeon-gaucho" (Infinite Architectural Hexagon). furthermore, by visualizing his name as a sqaure($\square$), he means to suggest the intentional image of his pen name as a ′box′.

The objects of the nature have three dimensional (3-D) parameters. The 3-D profiles are embedded on the photographs and microscopic images. To understand 3-D configuration, stereo pair image with thick section is frequently employed. The perception of 3-D images is possible with the aid of stereoscopic glasses, although the expert can perceive 3-D images without the glasses. Anaglyphic stereo images are constructed by various softwares from commercial and freeware. Here we would like to present an easy anaglyphs construction method with Adobe $Photoshop^{(R)}$ based on tilting paired images from high voltage electron microscope. The anaglyphic stereo images constructed revealed the same 3-D perception with conventional stereoscopy. We could zoom in/out the anaglyph image digitally to investigate the detail configuration by real time. This method is expected to contribute to understanding complex structures 3 dimensionally.

Because of the development of computers and high-technology applications, all devices that we use have become more intelligent. In recent years, security and surveillance systems have become more complicated as well. Before new technologies included video surveillance systems, security cameras were used only for recording events as they occurred, and a human had to analyze the recorded data. Nowadays, computers are used for video analytics, and video surveillance systems have become more autonomous and automated. The types of security cameras have also changed, and the market offers different kinds of cameras with integrated software. Even though there is a variety of hardware, their capabilities leave a lot to be desired. Therefore, this drawback is trying to compensate by dint of computer program solutions. Image processing is a very important part of video surveillance and security systems. Capturing an image exactly as it appears in the real world is difficult if not impossible. There is always noise to deal with. This is caused by the graininess of the emulsion, low resolution of the camera sensors, motion blur caused by movements and drag, focus problems, depth-of-field issues, or the imperfect nature of the camera lens. This paper reviews image processing, pattern recognition, and image digitization techniques, which will be useful in security services, to analyze bio-images, for image restoration, and for object classification.

Stereo image analysis has been an important tool for reconstructing 3D terrain. By In its nature, occlusion is one of difficulties we cannot avoid in stereo matching. This paper presents a study on occlusion detection by employing LRC(Left-Right Check) and OCC(Occlusion Constraint). Experimental results show that these method can effectively detect occluded regions and those regions are usually occurred around object contours and scene discontinuity.

Unsupervised methods for image segmentation are recently drawing attention because most images do not have labels or tags. A topic model is such an unsupervised probabilistic method that captures latent aspects of data, where each latent aspect, or a topic, is associated with one homogeneous region. The results of topic models, however, usually have noises, which decreases the overall segmentation performance. In this paper, to improve the performance of image segmentation using topic models, we propose two topic masks applicable to topic assignments of homogeneous regions obtained from topic models. The topic masks capture the noises among the assigned topic assignments or topic labels, and remove the noises by replacements, just like image masks for pixels. However, as the nature of topic assignments is different from image pixels, the topic masks have properties that are different from the existing image masks for pixels. There are two contributions of this paper. First, the topic masks can be used to reduce the noises of topic assignments obtained from topic models for image segmentation tasks. Second, we test the effectiveness of the topic masks by applying them to segmented images obtained from the Latent Dirichlet Allocation model and the Spatial Latent Dirichlet Allocation model upon the MSRC image dataset. The empirical results show that one of the masks successfully reduces the topic noises.

This article presents a study on the concept of "Photogenie", which refers to the duality and mentality of the photographic image, with the viewpoint regarding the photographic image by Edgar Morin. First, we will look at the evolution of the concept of "Photogenie". From the field of photography, the term "Photogenie" means objects that produce light, enough to impress the photographic plate. But theorists of cinema at the beginning of the 20th century have changed the meaning of the term. For Louis Delluc, the "Photogenie" means the effect of union between the reproduction of real and artistic genius. For Jean Epstein, the "Photogenie" means mental quality, nonmaterial or inderterminable, of the photographic and cinematographic image. But Morin synthesized the arguements of Delluc and Epstein. For him, the "Photogenie" indicates both a double character of the photographic image and its mental quality. Then, based on this concept of "Photogenie," Morin said on particular aspects in the photographic image. Considering photography as a double in the anthropological sense, it puts emphasis not only the dual nature of the photographic image but also mental and spiritual quality. Combining the theory of the mage Henri Bergson and Jean-Paul Sartre, he builds his own theory of the mage that concerns both photography and cinema. In short, to Morin, the photographic image is a place where coexist absence and presence, the real and the imaginary, perception and memory, the material and mental, as well that a place of mentality which appear all our memories, hallucinations, dreams, imagination etc.

In the modern popular culture, a significant code is not the truth itself but the seeming truth. To fulfill this function, it is a mythology that has a transcendental power to eliminate any doubt and mystery. That is to say, cultural uniqueness is understood as an identical thing through mass communication, and people perceive it as a similar cultural community. In this process, mythology form and accumulate the matrix of mythological meaning by eliminating the difference between the reality and the illusion. Such a matrix forces a meaningless and unconditional truth and practice without any criticism and reconsideration. This paper tries to extract art and cultural characteristics of mythological image through examining the relationship among mythological image, history, and ideology. For this aim, we make use of Roland Barthes' signs and Daniel Boorstin's image as a basic analytical tool. After that we examine the characteristics of mythological image appeared in modern cultural discourses and the relationship between mythological image and modern popular culture. Furthermore, we consider the mythological image expressed in modern fashion, which has the nature of commodity aesthetics.

There can be two definitions of modern ideal medical surroundings. One is medical services satisfied patients' with their desire and the other is places suited to remedy realized by rational operation. Particularly, in case of dental service, there is a need for an effective regard of moving lines and there are many rooms for a dental service belonged to a curer and not a curer. So a design has been developed by many concerns. flow do we proffer more familiar and comfortable places to both a curer and not a cuter. Nowadays, the design is making progress to the unprecedented and up-to-date direction. I would suggest a general plan used by a nature of an original art for this design. The design used by a nature between human beings and things is able to induce comforts and intimacies. So to speak, I would like to remove artificial design and keep up organic lines, shapes and forms of a nature like it is. This study grasps the organizational limitation of this design and the visual characteristic of organic forms used by harmonious image of a nature and a new way is applied to limited medical places, a dental service, based on the study. Also, I'm go to examine the meaning and worth of a new design and suggest the direction of it.
