【摘要】 提出一种用线性变换的广义模糊扩散法 ,对扫描进计算机的生理曲线图象进行增强、去噪处理 ,以达到去除坐标栅格和污迹 ,最后完整地提取出生理曲线的目的。本算法比轮廓搜索法与双结构元法具有算法简单快捷、不依赖于纸张扫描位置的优点 ,对提取出的生理曲线还进行了误差分析。实验结果表明 :本算法适宜大规模的生理曲线提取 ,是广义模糊算子 (GFO)的又一个成功应用。更多还原

【Abstract】 A new method based on generalized fuzzy set(GFS), called generalized fuzzy diffusion(GFD), for extracting physiological curves is presented. The method possesses strongpoints, such as simplicity, speediness and independence of scanning position. Error between the extracted curve and the original curve is defined. Experiments show that the method is fit for extracting massive physiological curves, and it is one of the successful applications of GFS.更多还原
