Plain objects detection in image based on a contour tracing algorithm in a binary image

Abstract

Objects detection in image is a central problem to many tasks in digital image processing and therefore it has a vast range of applications. An algorithm for plain objects detection in image based on a contour tracing algorithm in a binary image is presented in this paper. The detection of plain object in image relates to the decomposition of a binary image contour into contours and closed contours and is based on the developed by the author algorithms for: an applicant for the vertex detection in a binary image, a closed contour detection in a binary image. The algorithm for an applicant for the vertex detection in a binary image allows performing the decomposition of a binary image contour into contours and closed contours. The problem of the determination of the starting point for contour tracing algorithm in a binary image is considered. The experiments show the robustness and the efficiency of the algorithm.
