1. A computer-implemented image identification method, comprising:
acquiring, at one or more computing devices, a hand feature region within a sight from a first view by a skin color detection, and capturing and tracking the hand feature region in real time; acquiring, at the one or more computing devices, a feature and a position of a tip of a finger from the hand feature region by performing a pattern recognition for a morphological feature of a stretched hand, and capturing and tracking the feature and the position of the tip of the finger in real time in the first view; recording, using the one or more computing devices, an interframe displacement of a feature point of the tip of the finger when the tip of the finger delimits a periphery of a target object located in the first view to obtain a delimiting trajectory from the interframe displacement, and closing the delimiting trajectory to form a full-perimeter geometry; projecting, using the one or more computing devices, the full-perimeter geometry on a plane where a direction of the sight is perpendicular to a plane where the target object is located so as to obtain a projection region, so as to separate the projection region from the first view as a segmented image; and performing, using the one or more computing devices, an image identification using the projection region as an identification region of the target object. |
