본 논문은 가상공간 제작을 위해 다수의 카메라로 영상을 촬영했을 때, 영상 특성 차이를 감소시키는 방법 을 제안하였다. 각각 8 개의 본체와 렌즈를 교차 장착하여 64 개의 영상을 사용하였다. 영상 분석은 히스토그램과 픽셀 분포 값의 표준 편차를 분석 비교하였다. 분석결과, 동일 기종의 카메라임에도 불구하고, 렌즈 혹은 이미지 센서에 따라 각각 다른 영상 특성을 보여주었다. 본 논문에서는 이러한 차이를 보정하기 위해 영상의 전체 밝기 값의 분포를 조절하였다. 시뮬레이션 결과, 평균 편차가 최대 (실내 : 6.89, 실외 : 24.23) 이었으나, 시뮬레이션 진행 후 편차가 거의(실내 : 최대 0.42, 실외 : 최대 : 2.73) 없는 영상을 얻었다. 추후에는 영상 밝기 분포보다 정밀한 영상 분석 방법을 연구하고 적용할 것이다.

In this paper, we propose a method to reduce the difference in image characteristics when multiple camera images are captured for virtual space production. Sixty-four images were used by cross-mounting eight bodies and lenses, respectively. Image analysis compares and analyzes the standard deviation of the histogram and pixel distribution values. As a result of the analysis, it shows different image characteristics depending on the lens or image sensor, though it is a camera of the same model. In this paper, we have adjusted the distribution of the overall brightness value of the image to compensate for this difference. As a result, the average deviation was the maximum of (Indoor: 6.89, outdoor: 24.23), we obtained images with almost no deviation (Indoor: maximum 0.42, outdoor: maximum: 2.73). In the future, we will study and apply more accurate image analysis methods than image brightness distribution.

본 연구는 제품의 가격에 부과가 되어 있는 부가가치세(Value Added Tax)를 어떻게 표시(VAT 프레임: VAT포함, VAT별도)하느냐에 따라 소비자들의 가격제시방법에 대한 태도가 달라질 수 있음을 살펴보았다. 또한 사 고방식(종합적 vs. 분석적)에 따른 태도변화 즉, 조절효과도 살펴보았다. 이를 위해 실험자극물을 4가지 형태[(제품: 실용/쾌락)×(VAT: 포함/별도)]로 조작하였다. 1) 조사대상자들은 VAT별도 가격제시 방법보다 VAT포함 가격제시 방 법을 더 선호하는 것으로 나타났다. 2) 사고방식의 조절효과도 확인되었다. 즉 분석적 사고자의 경우에는 전자와 후 자 간에 유의미한 차이가 없는 것으로 나타났으며, 종합적 사고자의 경우에는 전자보다 후자를 더 선호하는 것으로 나타났다. 기업의 마케팅 실무 담당자들은 이와 같은 연구결과를 고려하여 효과적인 마케팅 전략을 수립하는데 도움 을 받을 수 있을 것으로 기대된다.

This study has examined the influence of VAT frame(VAT included vs. VAT excluded) on the consumer's attitude. Additionally, it has also examined the moderating effect of thinking style(holistic vs. analytic). The experiment stimuli were operated in 4 types[(product: utilitarian/hedonic)x(VAT: included vs. excluded)]. The results of this study can be summarized as follows. 1) The consumers preferred the VAT included frame to the VAT excluded frame. 2) The moderating effect of thinking style appeared. There is no meaningful difference between the VAT included frame and the VAT excluded one to analytic thinkers. But the holistic thinkers preferred the latter to the former. It is expected that this will be helpful to the person in charge of marketing for the company to establish an effective marketing strategy by considering these results.

본 논문은 호스트(PC) 기반의 직렬처리 방식으로 도로영역 추출 방식에 디바이스(Graphic Card) 기반의 병렬 처리 방식을 추가함으로써 보다 향상된 처리 속도를 가지는 도로영역검출을 제안하였다.

The OpenCV CUDA supports the many functions of parallel processing method by interworking a conventional OpenCV with CUDA. Also, when interworking the OpenCV and CUDA, OpenCV functions completed a configuration are optimized the User’s device(Graphic Card) specifications. Thus, OpenCV CUDA usage provides an algorithm verification and easiness of simulation result deduction. The proposed method is verified that the proposed method has a about 3.09 times faster processing speed than a conventional method by using OpenCV CUDA and graphic card of NVIDIA GeForce GTX 560 Ti model through experimentation.

본 논문은 평균이동방법과 연결요소방법을 이용하여 도로 영역을 추출하는 알고리즘을 제안하였다. 평균 이동 방법은 중심 모드를 찾기 위한 비모수적 통계 방법으로 컬러 영상을 분할하는데 효율적이다. 일반적으로, 영상의 중·하단에 위치하는 정보를 활용하여 도로의 특징점이 추출된다. 이 특징점과 분할된 컬러 영상을 이용하면, 도로의 영역을 추출할 수 있다. 그러나, 도로의 위치정보와 색상정보만으로 도로영역을 추출할 경우, 잡음과 도로 이외의 영역까지 추출되는 단점이 있다. 본 논문에서는 모폴로지 열기·닫기 연산을 이용하여 잡음을 제거하고, 연결요소 방법을 통하여 가장 큰 영역의 부분만을 추출하여 도로 영역으로 결정하는 방법을 제안한다. 제안된 방법은 실험을 통하여 잡음 제거와 보다 정확한 도로 검출됨을 검증한다.

In this paper, we propose a method for extracting a road area by using the mean-shift method and connected-component method. Mean-shift method is very effective to divide the color image by the method of non-parametric statistics to find the center mode. Generally, the feature points of road are extracted by using the information located in the middle and bottom of the road image. And it is possible to extract a road region by using this feature-point and the partitioned color image. However, if a road region is extracted with only the color information and the position information of a road image, it is possible to detect not only noise but also off-road regions. This paper proposes the method to determine the road region by eliminating the noise with the closing / opening operation of the morphology, and by extracting only the portion of the largest area using a connected-components method. The proposed method is simulated and verified by applying the captured road images.
