摘　　要：针对主动毫米波成像安检系统的个人隐私保护问题,提出了一种主动毫米波人体图像性别识别流程,包括图像预处理、人体躯干图像分割、性别特征提取、各特征值权重确定、性别识别图谱形成、基于图形数据库的图像分类识别和算法优化验证。提出了一种基于灰度值提取的局域直方图性别识别特征图谱,给出了不同图像主体直观、量化的性别特征表达。基于该图谱,提出了一种多特征、多权值性别识别方法,性别识别准确率高于80%,可对海量人体图像快速分类与筛选,从而采取针对性隐私保护措施。该算法已应用于毫米波安检产品,其可移植性高,运行速度快,识别率高,在同类安检设备中具有巨大的应用潜力。A human body image gender identification algorithm was proposed for active millimeter-wave into ging security systents. The procedure of the algorithm includes imaging preprocessing, human body image seg mentation, gender feature extraction, selection of weight of different characteristics, formation of gender lea ture maps, image classification identification and algorithm optimization verification based on map database. A kind of local histogram algorithm based on gray value extraction was proposed and an intuitive map for identif ying gender of the figure was given. On the basis of the map, a muhi weight, multi-characteristic gender iden tification method was proposed. The identification rate of the method is above 80%, which would be helpful to the fast identification of huge number of pictures and the taking of corresponding measures to protect human privacy. The algorithm had been used in millimeter wave body security checkpoints. Because of high portabili ty, fast running speed and high recognition rate, it would have great application potential in similar security e quipment.
