- W2400477679 abstract "디지털 영상에서 그림자는 영산 분석에 부정적인 영향을 미칠 수 있기 때문에 효과적으로 이동물체 검출 및 추적을 위해서는 그림자 제거가 필수적인 전처리 과정이다. 본 논문에서는 색도 영상, 밝기 변화 및 이동물체의 그림자 방향 특성을 이용해 그림자를 제거하는 알고리즘을 제안하였다. 제안하는 방법은 크게 두 단계로 구성이 되며, 첫 번째 단계로 현재 영상의 색도와 밝기 변화를 이용해 그림자 후보 영역을 제거하고, 두 번째 단계에서 이동물체의 최하위 화소 위치를 구하여그림자의 방향에 해당하는 그림자를 제거하였다. 그림자는 이동물체의 아래 영역에 위치하기 때문에 이동물체의 최하위 화소와 그림자의 방향을 알면 그림자를 제거할 수 있다. 실험 결과, 실제 이동물체 영역과 그림자 영역의 분리가 효과적으로 이루어졌으며, 이동물체 검출 및 추적 성능이 향상되었다. Shadow is a common physical phenomenon in natural images and may cause problems in computer vision tasks. Therefore, shadow removal is an essential preprocessing process for effective moving object tracking in video image. In this paper, we proposed the method of shadow removal algorithm using chromaticity, brightness distortion and direction of shadow candidate. The proposed method consists of two steps. First, removal process of primary shadow candidate region by using chromaticity, brightness and distortion. The second stage applies the final shadow candidate region to obtain a direction feature of shadow which is estimated by the thinning algorithm after calculating the lowest pixel position of the moving object. To verify the proposed approach, some experiments are conducted to draw a compare between conventional method and that of proposed. Experimental results showed that proposed methodology is simple, but robust and well adaptive to be need to remove a shadow removal operation." @default.
