摘要： A face detection apparatus for tracking a detected face between images in a video sequence comprises: a first face detector for detecting the presence of face(s) in the images; a second face detector for detecting the presence of face(s) in the images; the first face detector having a higher detection threshold than the second face detector, so that the second face detector is more likely to detect a face in an region in which the first face detector has not detected a face; and a face position predictor for predicting a face position in a next image in a test order of the video sequence on the basis of a detected face position in one or more previous images in the test order of the video sequence; in which: if the first face detector detects a face within a predetermined threshold image distance of the predicted face position, the face position predictor uses the detected position to produce a next position prediction; if the first face detector fails to detect a face within a predetermined threshold image distance of the predicted face position, the face position predictor uses a face position detected by the second face detector to produce a next position prediction.

摘要： A method of comparing a test image with a set of reference images. The method: divides the test image into one or more test regions; for each test region, compares the test region with one or more reference regions in one or more reference images and identifies the reference region that most closely corresponds to the test region; and generates a comparison value from the comparisons of the test regions with their correspondingly identified reference regions.

摘要： Apparatus is arranged in operation to perform a method of estimating the number of individuals in a scene. The method comprises generating, for a plurality of image positions within at least a portion of a captured image of the scene, an edge correspondence value indicative of positional and angular correspondence with a representation of at least a partial outline of an individual. Analysis of the edge correspondence value is used to detect whether each of the plurality of image positions contributes to at least part of an image of an individual.
