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： PROBLEM TO BE SOLVED: To provide a signal processor splicing a compressed bit stream B0 to a compressed bit stream A0. SOLUTION: A decoding means decoding bit streams A0 and B0, a switching means which is connected to the decoding means for generating a spliced bit stream C and comprises data from the bit stream B0 spliced to data from the bit stream A0 at a splice point and an encoding means which re-encodes the spliced bit stream C for supplying it to a down stream decoder having a down stream buffer are installed. The encoding means is controlled on a shift area in accordance with a track where the rate of a change or occupation is restricted to a maximum rate which is previously decided. The occupation of the down stream buffer is changed from the occupation of the bit stream A0 to the bit stream B0 on the shift area.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration in the image quality caused, when digital bit streams are joined. SOLUTION: Decoders 1, 3 decode MPEG-2 bit streams AO, BO and recoders 8, 10 recode outputs of the decoders 1, 3 into bit streams AI, BI, including only an I frame respectively. A switch S1 switches from the stream AI to the stream BI and joins the streams AI, BI. An I frame 12 stores the joined stream AI/BI and a coder 4 is used to again encode the joined stream AI/BI. An image type decision rule is used to decide a transient GOP that is produced from the joining. The length of the transient GOP is changed by comparing it with the GOP of streams A, B according to the rule. The transient GOP provides a prediction point of a position in the stream B, at which the value of the occupancy of a stream C matches with that of the stream B.
