ABSTRACT:
The present invention discloses an image preprocessing method capable of increasing the accuracy of face detection by enhancing the contrast between dark pixels and their surrounding bright pixels, and increasing the brightness difference between dark pixels and bright pixels. Even in insufficient and non-uniform lighting conditions, the eye-analogue segments of a human face are obvious; so as to make a subsequent algorithm using eye-analogue segments for detecting human faces and producing more accurate results.
