A system for integrating heart rate measurement and identity recognition is provided. The system includes a storage unit, an image sensor, an identity recognition unit and a frequency extractor. The storage unit stores a user information database. The image sensor captures a plurality of skin images of a user during a time period. The identity recognition unit receives a physiological feature from the user and recognizes the user by comparing the physiological feature with the user information database in the storage unit. The frequency extractor obtains a frequency signal by extracting a motion signal from the skin images according to the brightness change of the different color lights in the skin images during a time period. The frequency signal represents a frequency in a specific frequency interval, and it represents heart rate information of the user. A method for use in the above-mentioned system is also disclosed.

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.

摘要:
A shooting parameter adjustment method for face detection includes (A) acquiring an image; (B) dividing the image into a plurality of blocks, and calculating a brightness value of each of the blocks; (C) selecting at least one of the plurality of blocks, and adjusting a shooting parameter according to the brightness value of the selected block; and (D) acquiring another image according to the shooting parameter, and performing a face detection procedure with the another image. The shooting parameter adjustment method can automatically adjust a shooting parameter of an image capturing device according to brightness of different blocks in an image. Therefore, by using this method, the brightness of a face, no matter being too high or too low, can be adjusted to a value suitable for face detection, so as to improve the accuracy of the face detection procedure.
