Claim Text:
1. A method comprising: selecting, via detection circuitry, a face detection parameter subset from a plurality of face detection parameter subsets, wherein each face detection parameter subset comprises a subset of face posture models from a set of face posture models and a subset of image patch scales from a set of image patch scales; and using, via the detection circuitry, the selected face detection parameter subset for performing face detection in an image, wherein performing face detection comprises scanning at least a portion of the image using a sliding window configured to be slideable along a predetermined scanning pattern, wherein using the selected face detection parameter subset for performing face detection in the image further comprises: scanning at least a portion of the image using a sliding window in a spiral grid pattern having a scanning starting position, wherein using the selected face detection parameter subset for performing face detection in an image comprises: extracting an image patch from the image; estimating a posture of the image patch; determining one or more face posture models in the selected face detection parameter subset that are applicable to the estimated posture; and using only the face posture models determined to be applicable to the estimated posture for performing face detection in the image patch.
