Ecotourism refers to tourism that senses and observes superior natural resources, cultural resources and history around. Today, as the current leisure patterns of the people change, a healing trip to find nature is being activated. In this paper, we propose a platform design and construction for providing ecotourism information. In the proposed platform, first, the image file of the eco-tourism objects taken every day from the image capture device is collected, converted into a video, uploaded to the server, then, when the tourist arrives at the eco-tourism object, It is designed to be able to watch.

Although a numbed of variants of 2D HMM have been proposed in the literature, they are, in a word, too simple to model the variabilities of images for diverse classes of objects; they do not realize the modeling capability of the 1D HMM in 2D. Thus the author thinks they are poor substitutes for the HMM in 2D. The new model proposed in this paper is a hidden Markov lattice or, we can dare say, a 2D HMM with the causality of top-down and left-right direction. Then with the addition of a lattice constraint, the two algorithms for the evaluation of a model and the maximum likelihood estimation of model parameters are developed in the theoretical perspective. It is a more natural extension of the 1D HMM. The proposed method will provide a useful way of modeling highly variable patterns such as offline cursive characters.

In this paper, we proposed an intelligent surveillance system which can be determined by the overspeed of vehicle which continuously collects by video imaging device. Imaging device to capture images continuously, and filtering errors that occur as a natural, long-distance moving objects by comparing the images collected before and after the images. To measure the size of things, it proves that able to measure speed of the vehicle, depending on the amount of growing pixels using the pixel processing.

Noise is used to create realistic animations that look like natural phenomena as well as procedural textures and shapes by adding randomness to graphical applications. In this paper, we suggest a method to edit noise values to satisfy the constraints that reflect the user's demands while maintaining the inherent statistical features of the noise function. Noise editing uses optimization to minimize the difference between the statistical characteristics of the ideal and edited versions of a noise source. Using our editing method, detailed control of animation and shape data that include noise is possible.

The adhesive material was found for joining pottery fragments from Duurlig Nars, Mongolia estimated in AD 1C. In this study, analysis of natural substance for joining fragments of pottery was performed using gas chromatograph and mass spectrometer. As a result, it was identified triterpenoid substances, such as lupeol and betulin which were known to constituents of birch bark tar. It was suggested that Mongolian used adhesives made by birch bark tar for joining pottery fragments. Therefore if organic materials of ancient objects are systematically researched, it can provide significant evidence related to the way of life of ancient people.

This study explored the historical meaning and the present practices of Indonesian batik. Relevant literature was reviewed first; subsequently, interviews and observations were conducted to achieve the purpose of the study. Historically, batik was an integral part of the Javanese court art as well as a representation of each regional culture. Batik also became an important means to reveal a national identity in postcolonial Indonesia in the 1950s. There exist two types of traditional and modern type batik in present Indonesia. The traditional batik refers to batik tulis, batik cap, and the combination of tulis and cap. The modern batik is comprised of a batik print as well as the combination of the print and the traditional batik. The traditional batik was practiced at the small-sized village batik workshops and in the government batik research center. A few batik workshops often co-operate with modern screen print factories; however, the use natural dyes for the dyeing of batik cloth is rarely found. Batik was used for varied objects made from fabric materials that include clothing, small fashion items, living supplies and furniture, as well as fine art such as paintings and wooden crafts.

Measurements of the initial values lead to an inverse and mathematically unprecisely formulated problem. A precise definition of an inverse problem is possible. It is to state a mathematical model of a physical process with clearly defined initial and exit values for the system behind the process. One can grasp the idea of an inverse problem by considering the tire as a copy of the objects of nature in a room with observations. Interpretation of nature is generally a result of an inverse problem. On one hand, the tire may be represented through the sensory organs and the nervous system as well as the experiences of the developer's existing apparatus of the projection of reality. On the other hand, it may be represented by a physical law or a model that can be confirmed or is to be refuted with the help of suitable measurements. During reconstruction of a measuring signal and the identification of a black box that can be assumed to be linear and causal, the tire becomes a first type Volterra integral equation of the convolution type. But measurements of the initial values are always fuzzy, the errors grow and the system behavior can no longer be forecasted. Thus, we have to deal with a chaotic system. This chaos produces fractals in a natural way. These are self-similar geometric structures. This self-similarity is clearly visible in the design.

Point-based methods with experienced human operators are processed well in traditional photogrammetric activities but not the autonomous environment of digital photogrammetry. To develop more robust and accurate techniques, higher level objects of straight linear features accommodating element other than points are adopted instead of points in aerial triangulation. Even though recent advanced algorithms provide accurate and reliable linear feature extraction, extracting linear features is more difficult than extracting a discrete set of points which can consist of any form of curves. Control points which are the initial input data and break points which are end points of piecewise curves are easily obtained with manual digitizing, edge operators or interest operators. Employing high level features increase the feasibility of geometric information and provide the analytical and suitable solution for the advanced computer technology.

An asteroid family is a group of asteroidal objects in the proper orbital element space (a, e, and i), considered to have been produced by a disruption of a large parent body through a catastrophic collision. Family members usually have similar surface properties such as spectral taxonomy types, colors, and visible geometric albedo with a same dynamical age. Therefore an asteroid family could be called as a natural Solar System laboratory and is also regarded as a powerful tool to investigate space weathering and non-gravitational phenomena such as the Yarkovsky/YORP effects. We carry out time series photometric observations for a number of asteroid families to obtain their physical properties, including sizes, shapes, rotational periods, spin axes, colors, and H-G parameters based on nearly round-the-clock observations, using several 0.5-2 meter class telescopes in the Northern hemisphere, including BOAO 1.8 m, LOAO 1.0 m, SOAO 0.6 m facilities in KASI, McDonald Observatory 2.1 m instrument, NARIT 2.4 m and TUG 1.0 m telescopes. This study is expected to find, for the first time, some important clues on the collisional history in our Solar System and the mechanisms where the family members are being transported from the resonance regions in the Main-belt to the near Earth space.

Typical methods of active contour model for object contour extraction are snake and level. Snake is usually faster than level set, but has limitation to compute topology of objects. Level set on the other hand is slower but good at it. In this paper, a new object contour extraction algorithm to use advantage of each is proposed. The algorithm is composed of two main steps. In the first step, snake is used to extract the rough contour and then in the second step, level set is applied to extract the complex contour exactly. 5 binary images and 2 natural images with different contours are simulated by a proposed algorithm. It is shown that speed is reduced and contour is better extracted.
