  • This paper proposes a Haar Wavelet Feature Detector (HWFD) based on the Haar wavelet transform and average box filter. By decomposing the original image using the Haar wavelet transform, the proposed detector obtains the variance information of the image, making it possible to extract more distinctive features from the original image. For detection of interest points that represent the regions whose variance is the highest among their neighbor regions, we apply the average box filter to evaluate the local variance information and use the integral image technique for fast computation. Due to utilization of the Haar wavelet transform and the average box filter, the proposed detector is robust to illumination change, scale change, and rotation of the image. Experimental results show that even though the proposed method detects fewer interest points, it achieves higher repeatability, higher efficiency and higher matching accuracy compared with the DoG detector and Harris corner detector.

  • The purpose of this is to analyze the aesthetics characteristics of our modern sports fashion, and thereby, discuss them in the light of the overall mentality or the 20th century, and thus, present the conditions or sports fashion design meeting modem people's divers aesthetics values and desired. Modern sports fashion sues can be categorized into futurist sports style, erotic sports style and American sheet sports style. And the 20th century mentality characterized by changes of lifestyle, identity and aspiration has influenced the aesthetic features of such sports fashion sues, which can be summed up as follows; first, the futurist sports style applies the functional items and details of active sportswear to design, while heralding a positive and hopeful message of technology and future by using the material of hi-tech functions and senses. This sports style was affected much by shift from social status, attraction and wealth to demonstration of state-of-the-art science, pursuit of functionality in terms of shapes and materials, convenience through See combinations of sportswear items or design elements. Second, the erotic sports style based on minimalism attempted to express the erotic body beauty indirectly by exposing some parts of body or using the material pressed against the body. This sports style was closely related with the changes of sexual identity such as neutral sexualism, bi-sexualism and homo-sexualism. Lastly, the American street sports style was born from black Americarns' sports and dances. This spors style pursues “youth” beyond TPO concept As mass media and commercial sports developed, the young generation copied sports stars' uniforms or fashions to share honor, wealth and youth with them. In sort, the American sheet sports style was affected much by the so-called “heroism”. Such a changed object of aspiration influenced the aesthetic characteristics of American shot sports style directly.

  • OGC(Open GIS Consortium) suggests the 'OpenGIS Simple Feature Specification for CORBA' which is the OpenGIS implementation specification for CORBA to specify standard interfaces for reuse and interoperation among distributed heterogeneous GIS resources in the CORBA distributed computing environment. An OpenGIS server that supports this implementation specification moat correctly implement all interfaces defined in the OpenGIS implementation specification to be interoperable with wrapped GISs efficiently. In this paper, we have designed and implemented an OpenGIS server based an object relational GIS, called GEUS that integrates GIS and database technologies to provide spatial data types and spatial operators from the DBMS engine level. In the CORBA distributed computing environment, clients can access geospatial data stored in GIS wrapped by the OpenGIS server through the standard interfaces defined in the OpenGIS implementation specification for CORBA. In addition, clients can use geospatial operation features provided by a back-end GIS and interoperate with other GISs.

  • SURF is a robust local invariant feature descriptor and has been used in many applications such as object recognition. Even though this algorithm has similar matching accuracy compared to the SIFT, which is another popular feature extraction algorithm, it has advantage in matching time. However, these descriptors do not consider relative location information of extracted interesting points to guarantee rotation invariance. Also, since they use gray image of original color image, they do not use the color information of images, either. In this paper, we propose a method for improving matching performance of SURF descriptor using the color and relative location information of interest points. The location information is built from the angles between the line connecting the centers of interest points and the orientation line constructed for the center of each interest points. For the color information, color histogram is constructed for the region of each interest point. We show the performance of our scheme through experiments.

  • The intruder detection system using digital PIR sensor has the problem that it can't recognize human correctly. In this paper, we suggest a new intruder detection system based on analog PIR sensor to get around the drawbacks of the digital PIR sensor. The analog type PIR sensor emits the voltage output at various levels whereas the output of the digitial PIR sensor is binary. The signal captured using analog PIR sensor is sampled, and its frequency feature is extracted using FFT or MFCC. The extracted features are used for the input of neural networks. After neural network is trained using various human and pet's intrusion data, it is used for classifying human and pet in the intrusion situation.

  • The object of this research is to take a bilateral look into cultural exchanges of the Netherlands and Japan through the East India Company and thereby improve the general understanding in regards to the exchanges of costume cultures between the East and the West. The study conducted qualitative analyses on features of contemporary costumes of the Netherlands and Japan from 1602 to 1799 by investigating the secondary sources, such as the histories of costumes, arts, and literature. The results are as follows; the traditional sleeves of the Japanese Kimono were basically cut out in a straight line. However due to the growing popularity of the kimono home gown in Europe, the producers of the kimono in India as well as several other European countries modified them into western-style sleeves. Regarding the costumes of the Netherlands, which were introduced to Japan, the study found that Japan imported Dutch fabrics, instead of specific clothing items. In Japan, costume controls and anti-conspicuous consumption regulations among social classes including a closed-door policy had negative effects on both developments and exchanges of costumes of the country. However, when it comes to the Jinbaori, a costume for ruling classes, Japan was open to using fabrics, patterns and designs of the West. In light of what have been discussed so far, the study confirmed that the costume exchanges between the two countries started long after their first business of the general cultural exchanges. Though it is clear that the advancements in the natural sciences that the Japanese made can be attributed to the West, Japan was one of the nations that impacted the costume cultures in Europe.
