Abstract:
1. A human face recognition method for use in an electronic device, the electronic device comprising a processor and a memory unit, the memory unit having a plurality of human face images stored therein, the human face recognition method comprising the steps of: (a) enabling the processor to calculate a piece of red component statistic information, a piece of green component statistic information, and a piece of blue component statistic information for each of the human face images; (b) enabling the processor to process at least two colors of the pieces of red component statistic information, the pieces of green component statistic information, and the pieces of blue component statistic information by an independent component analysis algorithm so as to derive a piece of first component information and a piece of second component information; (c) enabling the processor to derive a piece of first frequency-domain information and a piece of second frequency-domain information by respectively transforming the piece of first component information and the piece of second component information into a frequency domain; (d) enabling the processor to calculate an energy value of the piece of first frequency-domain information within a frequency range; and (e) enabling the processor to decide whether the human face images are captured from a human being by comparing the energy value with a preset value.
