  • The Active Appearance Model (AAM) is a class of deformable models, which, in the segmentation process, integrates the priori knowledge on the shape and the texture and deformation of the structures studied. This model in its sequential form is computationally intensive and operates on large data sets. This paper presents another framework to implement the standard version of the AAM model. We suggest a distributed and parallel approach justified by the characteristics of the model and their potentialities. We introduce a schema for the representation of the overall model and we study of operations that can be parallelized. This approach is intended to exploit the benefits build in the area of advanced image processing.

  • Data fusion is method to combination data. The purpose of this study is to design and implementation for street fashion information analysis system using data fusion. It can offer variety and actually information because it can fuse image data and survey data for street fashion. Data fusion method exists exact matching method, judgemental matching method, probability matching method, statistical matching method, data linking method, etc. In this study, we use exact matching method. Our system can be visual information analysis of customer's viewpoint because it can analyze both each data and fused data for image data and survey data.

  • Exact histogram specification (EHS) transforms the histogram of an input image into the specified histogram. In the conventional EHS techniques, the pixels are first sorted according to their graylevels, and the pixels that have the same graylevel are further differentiated according to the local average of the pixel values and the edge strength. The strictly ordered pixels are then mapped to the desired histogram. However, since the conventional sorting method is inherently dependent on the initial graylevel-based sorting, the contrast enhancement capability of the conventional EHS algorithms is restricted. We propose a modified EHS algorithm considering the just noticeable difference. In the proposed algorithm, the edge pixels are pre-processed such that the output edge pixels obtained by the modified EHS can result in the local contrast enhancement. Moreover, we introduce a new sorting method for the pixels that have the same graylevel. Experimental results show that the proposed algorithm provides better image enhancement performance compared to the conventional EHS algorithms.

  • To show a retina shape and thickness on the computer, a laser has been used in Scanning Laser Ophthalmoscope (SLO) equipment using the travelling difference. This method requires exact synchronize control of laser travelling in optic system to show this image. In this study, a synchronize control of the galvanometer to make 3-dimentional retina image. To obtain a clear 3-dimentional image, this exact synchronism is very Important for making perfect plane scanning.

  • To show a retina shape and thickness on the computer monitor, a laser has been used in Scanning Laser Ophthalmoscope(SLO) equipment using the travelling difference. This method requires exact synchronous control of laser travelling in optic system to show a clear 3-dimensional image of retina. To obtain this image, this exact synchronism is very important for making the perfect plane scanning. In this study, a synchronous control of the galvanometer using deadbeat torque observer to make 3-dimensional retina image is presented. For the more, a very simple mathematical model of the galvanometer is approved by experimental result.

  • 본 논문은 DSP보드에 캠코더의 NTSC 카메라로부터 획득한 칼라영상에서 휘도성분만을 추출한 후 비교적 간단한 영상 처리를 하여 카메라 렌즈의 초점 조절에 필요한 정보를 추출하여 자동으로 초점이 조절되는 시스템을 구현 하였다. 초점이 정확한 물체는 경계선이 뚜렷하다는 점을 이용하여 영상을 미분한 후 실험적으로 구한 초점조절에 유효한 값의 합이 증가하는 쪽으로 렌즈를 조절함으로서 영상에 적합한 초점을 얻을 수 있었다. 또한 잡음 성분에 해당하는 미분 값이 큰 값은 제외함으로서 보다 정착한 초점 값을 얻을 수 있었다.

  • Image detection system for road traffic data analysis is a real time detection system using image processing techniques to get the real-time traffic information which is used for traffic control and analysis. One of the most important functions in this system is to match the coordinates of real world and that of image on video camera. When there in no way to know the exact position of camera and it´s height from the object. If some points on the road of real world are known it is possible to calculate the coordinates of real world from image.
