摘要
This invention relates to a method and a device for human body gender detection in a microwave image. The structure feature of a human body itself as well as the constructed vertical direction spatial distribution histogram and horizontal direction spatial distribution histogram are used to accurately locate the chest position and the crotch position of the human body. A human body chest subimage is extracted according to the chest position, and a human body crotch subimage is extracted according to the crotch position. Then, the feature values of the human body chest subimage and the human body crotch subimage are respectively extracted by a feature value extraction algorithm, and the human body gender is automatically identified according to the feature values. The technical solution of this invention is simple, and after experimental verification, can be effectively applied in actual microwave security check system. This technical solution has high real time and high robustness, and its correct recognition rate meets the operating requirements. As such, the problem of how to identify human body gender in real time and accurately in a microwave security check system is solved. Besides, because the present invention can accurately locate the chest position and the crotch position of a human body, the human body's private part can be shielded and protected effectively according to this invention.
