1. A method for face detection using face region location and size predictions, applicable to a computer system, said method comprising the steps of:
- performing face candidate region location and size predictions on an input image, which including image regionalization, region labeling and feature capturing, distance transform with constraint, and face location and size estimation, to predict at least a face location and size range for said input image; and
according to said at least a predicted face location and size range, performing an adaptive face detection, further comprising;
establishing face detection range, establishing window size range used for face detection, and dynamically determining at least an optimal face location for each scale of a pre-defined number of scales until at least an optimal face region being verified as face location or all scales being verified, and outputting a final face detection result.

Abstract
In one exemplary embodiment, a face detection method implemented in a computer system estimates location and size of face candidate regions for an input image, which includes image regionalization, region labeling and feature capturing, distance transform, and face location and size estimation, to predict at least a face location and size range for the input image. According to the at least a predicted face location and size range, the method further performs an adaptive face detection until a predicted face region is verified.
