High-performance image contour delineation method based on piecewise cubic Bezier curves fitting

摘要

Digital image contour is rich in image information, many applications are based on accurate tracking of the target contour. Image contour features fuzziness and non-uniformity, so that contour extraction method based on automatic delineation can easily cause inaccurate partition, while manual partition method has poor efficiency and instantaneity. Considering accuracy and efficiency of two-dimensional (2-D) contour delineation, a high-performance digital image contour delineation method based on piecewise cubic polynomial Bezier curve fitting is established in this paper. The experiment results demonstrate that this method is easy to realize, simple to calculate and applicable for various computer hardware platforms. Specific to different partition objects, anchors with an appropriate quantity can adopt to regional geometric shapes and raise efficiency, accuracy and precision of contour tracking.
