The results show that the distribution of macro-hardness presents gradientchange, the subsurface layer's hardness is highest, its is 542 HV.
结果表明:渗层到基体的显微硬度呈梯度变化,最高硬度出现在亚表层,硬度为542 HV ;

Through analyzing the image gradient, this model used second order model to denoise at the region with obvious gradientchange and the region with tiny gradientchange.
该模型通过对图像梯度的分析,在梯度变化剧烈区域和梯度变化微小区域利用二阶模型去噪以提高去噪效率;
