Abstract
A method, a system, and a computer-readable recording medium for long-distance person identification are provided. The method is applicable to a system having an image capturing device and a depth sensor and includes the following steps. An image of a user is captured by using the image capturing device to generate a user image, and depth information of a user is detected by using a depth sensor to generate user depth information. Soft biometric features of the user are obtained according to the user image and the user depth information, where the soft biometric features include silhouette information and human body features. A soft biometric feature similarity of the user is calculated based on the soft biometric features by using registered information of registered users so as to output a person identification result accordingly.
