    Abstract: A human body gender automatic recognition method and apparatus. The human body gender automatic recognition method comprises the following steps: acquiring a current millimeter wave grayscale image to be recognized, and determining gender part region positions of a human body in the millimeter wave grayscale image according to a pre-set body proportion; extracting a region sub-image corresponding to the gender part region position; performing dimension normalization on the region sub-image to obtain the region sub-image after normalization; performing feature information extraction on the region sub-image after normalization to obtain feature information about the region sub-image after normalization; recognizing the millimeter wave grayscale image by means of each pre-set classifier corresponding to the feature information according to the size order of feature distances, and respectively outputting results; and integrating the output results to obtain a classification recognition result of the millimeter wave grayscale image. The method has relatively high recognition rate and calculation efficiency, and solves the problem of a privacy protection and detection method in a millimeter wave security inspection system.

    Abstract: 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.
