摘要
为了实现人体器官的三维重建,如何准确、有效地提取二维医学图像的边缘成了首要解决的问题。我们提出一种新的图像边缘提取方法,该方法先将原始CT图像二值化,然后利用数学形态运算对二值化图像进行预处理,最后利用Canny算子提取图像边缘。通过肾脏CT图像边缘提取结果表明,该方法简单、高效、性能优越。
To reconstruct the body organs in 3-D, how to extract the edges from 2-D medical images accurately and effectively has benen the primarily problem. Therefore, a new method of edge extraction was introduced in this paper. The original CT image was binarized firstly and then preprocessed by mathematical morphology operating. Finally, the image edge was extracted by the Canny algorithm. The results of kidney CT image edge extraction show that the method is simple, efficient and superior performance.
