Abstract: 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.

Abstract: 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.

Abstract: 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.
