Scale space filter can restrain noise and recognize edge reliably in big scale , and can confirm positions accurately in small scale , at last get the true positions of edge by focus processing from big scale to small scale . but traditional canny arithmetic based on guass scale space have shortcomings such as big computing and confirming positions inaccurately 尺度空间滤波能在大尺度下抑制噪声可靠的识别边缘,在小尺度下精确定位,最后由粗及精地进行边缘聚焦而得到边缘的真实位置,但是传统的基于guass尺度空间的canny算子计算量大,定位不够精确。
Further more , this algorithm also provides the criterion distinguishing edge inflexion and sleek curve section and the method computing inaccurately curvature radius and approximate perimeter . the paper also introduces the use method with cell edge hollow repairing and overlap or conglutination cell segmentation . for example , this algorithm has proved high - speed and has a good effect of cell segmentation on more than twenty groups of conglutinate and absent cells which are gathered from three kinds of cells 同时给出了利用这些参数判别边界角点,边界光滑段的判据,以及估算曲率半径,等效周长的方法;最后,以细胞边界凹陷的修补和重叠细胞粘连的分割为例验证了算法的可行性,该算法在采集到的30余组粘连和缺损细胞上进行了验证,结果表明,该算法处理速度快,分割效果良好。
