Face-detection processing methods, image processing devices, and articles of manufacture are described. According to one arrangement, a face-detection processing method includes accessing image data of a plurality of images to be processed for detection of human faces in the images, determining whether or not to use skin-detection processing for face-detection processing of individual ones of the images, and in accordance with the determining, performing the face-detection processing of one of the images using the skin-detection processing to detect human faces in the one of the images and performing the face-detection processing of another of the images without using the skin-detection processing to detect human faces in the another of the images.

Face-detection processing methods, image processing devices, and articles of manufacture

Systems, methods, and other embodiments associated with increasing face detection speed are described. One example method includes determining whether to control a face detection process to selectively perform a face detection in a patch in a digital image. The face detection may be based, at least in part, on determining whether the patch overlaps a face previously identified by the face detection process. The example method may also include providing a signal to control the face detection process to perform the face detection upon determining that a patch overlap does not exceed an overlap factor.

Increasing face detection speed

Systems and methods are disclosed that determine a largest patch size to traverse a digital image, analyze the digital image to detect one or more first objects of a size approximately the same as the largest patch size, and discontinue analyzing the digital image when the digital image includes the first object(s) of a size approximately the same as the largest patch size. The patch size is decremented to progressively smaller patch sizes if the first object(s) of a size approximately the same as the largest patch size is not detected and the digital image is further analyzed to detect one or more first objects of a size approximately the same as the smaller patch size until the first object(s) are detected or the patch size is decremented below a predetermined smallest size.
