摘要

人脸分析是图像处理中的一项重要任务。这些任务大多集中在人脸识别和检测上。欺骗自动面部分析系统的不同方法之一是在皮肤上标记符号。另一方面,一些应用试图消除面部缺陷。因此,在本文中,我们试图检测和去除脸上的皮肤痕迹,无论它们是自然的还是非自然的。我们的算法将人脸图像通过适当的过滤器得到候选标记,然后利用候选标记图像像素的8点邻域关系创建一个图空间。然后,我们使用基于出现强度、形状密度、局部唯一性和色差的四种度量来计算每个候选标记的概率。然后使用阈值来区分分数和假考生。最后,我们利用标记周围最相似的邻近区域将标记从皮肤上去除。我们的算法在痣检测和去除方面具有显著的准确性。

Facial mark detection and removal using graph relations and statistics
Face Analysis is an important task in image processing. Most of these tasks centralized on face recognition and detection. One of different ways for deceiving automatic face analysis systems is mark notation on the skin. On the other hand some applications attempts to eliminate defects of the face. Hence, in this paper we try to detect and remove skin marks on the face, whether they're natural or not. Our algorithm passes face image through appropriate filters to get mark candidates and then create a graph space using 8-point neighborhood relations of mark candidates image pixels. Then we compute probabilities of each mark candidate using four measures based on intensity of occurrence, shape density, uniqueness in local area and color difference. Then using a threshold, we distinguish marks and false candidates. Finally we use the most similar adjacent area around mark to remove the mark from skin. Our algorithm represents significant accuracy in mole detection and removal.
