针对公安实战和司法鉴定的特殊要求——保持高度原始图像特征的性质,抛弃了在图像特征 定位、提取之前采用边缘提取和二值化对图像进行预处理的传统方法,利用模板匹配的方法 对颅骨重要特征的提取进行了研究。根据颅骨像的灰度特性和特征的几何形状提出了一种简 便、快速、有效的模板匹配提取特征点的方法。并给出了较详细的论述。 In view of the special requirements of actual combat and forensic appraisal of public security, the traditional method of preserving the characteristics of highly primitive images, abandoning the image preprocessing using edge extraction and binarization prior to image feature location and extraction, the template matching method is used The extraction of important features of the skull was studied. According to the gray-scale characteristics of skull image and the geometric shape of the feature, a simple, fast and efficient template matching method for extracting feature points is proposed. And gives a more detailed discussion.
