In this article, we present a new DICOM object able to create image-based annotations in DICOM image. Since the proposed image-based annotation uses images themselves of annotation, various types like character, sketch, and scanning image, etc., can be imported into annotation easily. The proposed annotation is inserted into DICOM image directly but they do not influence original DICOM image quality by using independent data channel. The proposed annotation is expected to be very useful to medium and small clinics that cannot afford picture archiving and communication systems or electronic medical record.

As the number of vehicles has been sharply increases, the significance of safety and effective operation issues in the parking lot is being emphasized, which takes a part of the transportation system. Recently, there have been several studies for the parking management by detecting moving object, however, recognizing numbers of fast-moving vehicles simultaneously in the picture is still a challenging problem. The parking lot in public area, or large-sized buildings has clear parking section, whereas the sensor system is configured to monitor a plurality of parking spaces. Therefore, by considering those parking lots, we suggested to develop the real-time parking availability information system by applying the real-time image processing techniques. with the help of template matching. Following the study, we wanted to provide the alternative method for parking management system through the reference template makers by recognizing movements of parked vehicles with the size and shape, regardless of direct detecting of driving movements. In addition, we evaluated the applicability and performances of the information system, presented in this study, and implemented a prototype system to simulate the parking statuses of each floor. In fat, it was possible to manage and analyze statistics about the total number of parking spaces and the number of vehicles parked through real-time video flames. We expected that the result of the study will be advanced, following the user-friendliness and cost reduction in operating parking management system and giving information by efficient analysis of parking situation.

Recently, the smart applications, such as smart phone and smart TV, become a hot issue in IT consumer markets. In particular, the smart TV provides 3D video services, hence efficient coding methods for 3D video data are required. Three-dimensional (3D) video involves stereoscopic or multi-view images to provide depth experience through 3D display systems. Binocular cues are perceived by rendering proper viewpoint images obtained at slightly different view angles. Since the number of viewpoints of the multi-view video is limited, 3D display devices should generate arbitrary viewpoint images using available adjacent view images. In this paper, after we explain a view synthesis method briefly, we propose a new algorithm to compensate view synthesis errors around object boundaries. We describe a 3D warping technique exploiting the depth map for viewpoint shifting and a hole filling method using multi-view images. Then, we propose an algorithm to remove boundary noises that are generated due to mismatches of object edges in the color and depth images. The proposed method reduces annoying boundary noises near object edges by replacing erroneous textures with alternative textures from the other reference image. Using the proposed method, we can generate perceptually inproved images for 3D video systems.

We usually try to accomodate ourselves to our nature surroundings interacting with nature. There fore I've decided to apply nature materials, esp. the pine to Hair Art as a way of expressing our feelings from Nature. 'Hair Art' is a follow-up study based on the various artistic point of view. There has been various works of 'Hair Art' with nature materials. However, it is rare to see a work of 'Hair Art' with the pine. That's why I've decided to study more about this. This study is a new experiment in 'Hair Art' against a conventional idea "Hair Art values practicability." Therefore, the primary goal of this study is to do much for the cause of learning in 'Hair Art' and encourages some development of 'Hair Art' industry. I've researched an image of a pine tree in art of Joseon Dynasty and contemporary art. Then I've tried to apply the image to a work of 'Hair Art'. First of all, in a view of expression technique for the symbolism of the pine, the artists in Joseon Dynasty drew pictures of a pine tree with a paintbrush but the modern artists make a new attempt from the thought of Modernism. We can find it in some photos. Next, to express traditional oriental idea such as 'unconventional and elegance', comtemporary artists chose the symbolism of the pine tree as an object of their works like pen and ink sketches from the thought of Modernism. Third, in a fusion style picture which contains features of both oriental paintings and western paintings and in a sexualism style picture that depicts a harmony of a male and a female as a shape of a pine, we can find colorful images of a pine tree and Their figurative beauty in art. Those are another symbols of the pine. In conclusion, the implication of the pine tree still hasn't changed even there are differences of drawings of pine tree in the past and the present. I've tried to combine these symbolic ideas of the pine with 'Hair Art' and made 5 hair styles. Throughout the process of researching this topic which is 'The Study of Hair Art Using The Symbolism of The Pine', I've realized that pine trees make it possible to express intrinsic tough spirit of human being and abundance in color and figurative beauty in art. I hope this can contribute to the field of 'Hair Art' and would become an important educational resource for further study.

In order to obtain a fine picture, a camera has many convenient functions. Its representative functions are Auto Focus(AF), Auto White Balance(AWB) and Auto Exposure(AE). In this paper, we present the new algorithm of Auto Exposure control system, one of its useful functions The proposed algorithm of Auto Exposure control system is based on IIR Filter with Variable Time Constant. First, in order to establish the standards of exposure control, we compare change of the picture luminance with luminance of an object in the Zone system. Second, we make an ideal characteristic graph of luminance by using the results. Finally, we can find the value of the right exposure by comparing an ideal characteristic graph of the luminance with the value of the current expose of a scene. We can find an appropriate exposure as comparing the ideal characteristic graph of the luminance with current exposure of a scene. In order to find a suitable exposure state, we make use of IIR Filter instead of a conventional method using micro-controller. In this paper, the proposed system has therefore simple structure, we use it for compact image sensor module used in the handheld device.

In this paper, we propose a novel video quality function for video processing based on MSSSIM to select an appropriate video processing filter and to accommodate multiple processing filters to each pixel block in a picture frame by a mathematical selection law so as to maintain video quality and to reduce the bitrate of compressed video. In viewpoint of video compression, since the properties of video quality and bitrate is different for each picture of video frames and for each areas in the same frame, it is difficult for the video filter with single property to satisfy the object of increasing video quality and decreasing bitrate. Consequently, to maintain the subjective video quality in spite of decreasing bitrate, we propose the methodology about the MSSSIM as the measure of subjective video quality, the KL-Divergence as the measure of bitrate, and the combination method of those two measurements. Moreover, using the proposed combinatorial measurement, when we use the multiple image filters with mutually different properties as a pre-processing filter for video, we can verify that it is possible to compress video with maintaining the video quality under decreasing the bitrate, as possible.

Conventional design producing systems using the Internet are largely classified into two groups: a basic type in which an operator of a design producing site receives an order for manufacture of a design from a purchaser, produces the design based on the content of the received order, and delivers the produced design to the purchaser; and a type in which a purchaser inspects given designs and select one of them for purchasing. Such conventional design producing systems have following problems. Firstly, receiving an order over the internet and delivering a produced design to a purchaser has nearly the same procedure as a conventional logo design procedure with the sole exception that an order can be received through the Internet. Therefore, the production of a design still costs a great deal and takes much time. Secondly, inspecting given designs, selecting one and producing the selected design is like simply selecting a picture, and thus a purchaser is not allowed to modify a design. To solve the above problems, it is an object of the present a new solution to provide a self-design producing system and method using network, in which a purchaser searches a design database for a design suitable for the purchaser's company, determines a design database by modifying design conditions, and makes an order for manufacture of a product to which the determined design is applied, through the Internet.

Geisha's gorgeous kimonos and grotesque make-up was the object of envy to Japanese women. There is a line in the movie like "Kimonos to the Geisha is the same as colors to the painter." Likewise, splendid patterns and colorful kimonos were an indispensible method or symbol for showing their artistic accomplishments. The purpose of this study is to investigate concept and origin of Geisha and their dress and decoration, analyze the dress of the people which appear in the movie, , arrange the expression of Geisha's dress as a movie costume, compare the difference of the dress by the career of Geisha and look back the disappearing aesthetic sense of Geisha. First, since Geisha appeared for the first time in Kyoto in 1751, it has become the world-wide representative of Japanese woman's images so that its existence oneself has become the tradition. Second, Geisha created fashion of various clothes, adornments, and hair styles as a creator of the popularity. Third, the strict regulation without exception is applied in Geisha's clothing, make-up, and motion tuned Samisen, Japanese traditional strings, and there is some difference in their hair style and dress by age of Maiko. Fourth, it is famous for unique make-up that Geisha makes up their faces, necks, and shoulders white, newly paints eyes, nose, lip line like drawing a picture in a pure white paper. Geishas put a little make-up as they have a higher position. Fifth, a heroin, Chiyo, shows clothing as a maid, an apprentice Geisha-Maiko- and a formal Geisha according to time flow. The length of kimono, textures, and hair decorations are longer, more splendid, and are more various as time goes. On the other hand, her make-up is lighter.

Recently, it is important to process multimedia data efficiently. Especially, in case of retrieval of multimedia information, technique of user interface and retrieval technique are necessary. This paper proposes a new technique which detects cuts effectively in compressed image information by MPEG. A cut is a turning point of scenes. The cut-detection is the basic work and the first-step for video indexing and retrieval. Existing methods have a weak point that they detect wrong cuts according to change of a screen such as fast motion of an object, movement of a camera and a flash. Because they compare between previous frame and present frame. The proposed technique detects shots at first using DC(Direct Current) coefficient of DCT(Discrete Cosine Transform). The database is composed of these detected shots. Features are extracted by HMMD color model and edge histogram descriptor(EHD) among the MPEG-7 visual descriptors. And detections are performed in sequence by the proposed matching technique. Through this experiments, an improved video segmentation system is implemented that it performs more quickly and precisely than existing techniques have.

Many pictures are taken at a construction site, but the information of the pictures is not managed in an efficient and systematic manner. For this reason, when a construction worker has scant field experience or knowledge, it is hard to communicate with others efficiently. Therefore, the information of the pictures taken is not fully utilized in any deliberation or conflict among interested parties, facilities maintenance, and construction of another structure, although they were taken for those purposes. This study discusses the need for combining vector-photos with image and 5W and 1H information, and develops a prototype module for creating vector-photos and saving them in a server. The vector-photos taken can be saved to a server in real time, and efficiently managed by a DB system. If a system to link the vector-photos with a BIM model is developed in the future, it is expected that the vector information in the picture can be connected with the property information of an object. As a result, the vector-photos can be utilized in more diverse ways.
