Linear Feature Detection of Rectangular Object Area using Edge Tracing-based Algorithm

에지 트레이싱 기법을 이용한 사각형 물체의 선형 특징점 검출

In this paper, we propose an algorithm to extract rectangular object area such 3s Data Matrix two-dimensional barcode using edge tracing-based linear feature detection. Hough transform is usually employed to detect lines of edge map. However, it requires parametric image space, and does not find the location of end points of the detected lines. Our algorithm detects end points of the detected lines using edge tracing and extracts object area using its shape information.
