MATLAB在图形边界特征提取中的应用

Application of MATLAB in Drawing Boundary Feature Extraction

图形轮廓特征的提取是一项十分重要的数字图像处理技术。提出了一种利用MATLAB进行图形边界特征提取的方法,介绍了处理过程中的几个重要步骤:图像保存;调入MATLAB;边缘检测;确定边界像素点坐标;拟合图形边界轮廓。实验结果表明,该方法具有较好的边界特征提取能力。

Extraction of the boundary feature from graph is a very important digital image processing technology. In this paper, a method of extracting the boundary feature with the MATLAB is proposed. Several important steps in the process are intro-duced, such as saving the image file, tuning into the MATLAB, edge detection, determining the boundary pixel coordinates, fitting graphic boundary and so on. The results show that the new method has better capability of boundary feature extraction.
