摘要:
A human face recognition method and apparatus are provided. A processor of the human face recognition apparatus calculates red, green, and blue component statistic information for each of a plurality of human face images. The processor uses an independent component analysis algorithm to analyze component statistic information of two colors and derive a piece of first component information and a piece of second component information. The processor transforms the pieces of first component information and second component information into a frequency domain to derive a piece of first frequency-domain information and a piece of second frequency-domain information. The processor calculates an energy value of the first frequency-domain information within a frequency range. The energy value is used to decide whether the human face images are captured from a human being.
