摘要: 通过引入加性算子分裂(Additive Operator Splitting, AOS)方法对测地线活动轮廓模型进行数值离散, 并将这种方法应用于尿沉渣显微细胞图像的分割中. 该数值格式为隐格式, 克服了显格式数值不稳定的缺点, 加快了收敛速度, 取得了令人满意的实验结果.

关键词: 测地线模型, 加性算子分裂, 图像分割

Abstract: An addtive operator splitting (AOS) method is introduced in the geodesic active contours model and used in microscopic cell segmentation of urine sediment. The discretization scheme is implicit and unconditionalstable. It overcomes the drawback of unstable for explicit scheme. The experimental result is satisfying.

Key words: geodesic active contours, additive operator splitting, image segmentation
