由於十二导程心电图是三度空间的心电讯号投射结果，然而传统的心电图所呈现资讯仅限於时间与振幅的二维变化，缺乏时间与空间整体资讯的呈现；以致於判读诊断上，由於欠缺整体资讯呈现，医师需在脑中进行组合辨识，过程较为繁琐，且对某些病症不易以目视判断。

Firstly, nonlinear diffusion filter was used to wipe of noise efficiently and kept the edge information of the image. Secondly, gradient calculation of pixel diagonal direction was considered in the calculation of neighborhood gradient amplitude which further repressed the impact of noise. Thirdly, using average interclass variance, the self-adaptively double thresholds for different images were calculated.

首先采用非线性扩散滤波减少了图像噪声，同时保持图像的边缘信息；在邻域梯度幅值计算中，考虑像素对角线方向的梯度，进一步抑制了噪声的影响；最后采用平均方差阈值法选取阈值，从而提高了对不同图像的自适应性。
