This algorithm includes three steps: firstly,the melanoma image with hairs is enhanced by morphologic closing-based top-hat operator and then segmented through statistic threshold;secondly,the hairs are extracted based on the elongate of connected region;thirdly,the hair-occluded information is repaired by the image repair technology based on partial differential equation(PDE).
该算法包含3个步骤:首先,运用形态学闭top-hat算子对毛发进行增强,并采用统计方法对图像进行二值化;然后,根据连通区域的延伸性特征提取出毛发;第三,运用基于偏微分方程的图像修复技术对毛发遮挡部位的信息进行修复。
The different viewpoints of life and death were also shown on portraits.
