Abstract

The invention discloses a multi-mode face identification device and method fusing grey information and depth information. The method mainly comprises the following steps: identifying the face grey information; identifying the face depth information; splicing all characteristics to form a characteristic pool after obtaining a characteristic of each data source by utilizing a characteristic layer fusion strategy, then picking out a characteristic most effective to classification from the characteristic pool by utilizing an Adaboost algorithm, and finally calculating a matching score by utilizing a nearest neighbor classifier based on the characteristics obtained by multi-mode characteristic layer fusion to realize multi-mode face identification, wherein a weak classifier is created for each characteristic in the characteristic pool. With the adoption of the scheme, a multi-mode system overcomes certain inherent weakness of a single-mode system by acquiring the two-dimensional grey information and the three-dimensional depth information, utilizing the advantages of the two-dimensional grey information and the three-dimensional depth information and applying the fusion strategy, so that the performance of a face identification system is effectively improved and face identification is more accurate and quick.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a multi-modal face recognition device and method for fusing grayscale information and depth information. Background technique [0002] Compared with 2D face recognition, 3D face recognition has the advantages of being robust to illumination and less affected by factors such as posture and expression. Therefore, after the rapid development of 3D data acquisition technology and the great improvement in the quality and accuracy of 3D data, Many scholars devote their research to this field. [0003] CN20101025690 proposes the relevant features of three-dimensional bending invariant to describe the characteristics of human face. This method extracts the relevant features of the bending invariant by encoding the local features of the bending invariant of adjacent nodes on the surface of the three-dimensional face; signs the relevant features of the bending invariant and uses ...
