Verfahren zur zeitlichen Segmentierung eines Videos in Videobildfolgen und zur Auswahl von Keyframes fuer das Auffinden von Bildinhalten unter Einbeziehung einer Subshot-Detektion

DE 102007013811 A1 UPAB: 20081013 NOVELTY - The method involves carrying out shot-detection, in which a video is temporally segmented into individual shots. Each subshot includes a video image consecutively in a sequence. Subshot-detection, in which each shot is temporally segmented into individual subshots, is carried out. Each subshot contains a video image of shots with a small change in the image content. Difference in simple image characteristics of different video images in shot is analyzed and evaluated as a proportion. Key frame-selection, in which an individual key frame is assigned to each subshot, is carried out. USE - Method for temporal segmentation of a video into video image sequences. ADVANTAGE - The method carries out key frame-selection, in which an individual key frame is assigned to each subshot, where subshots only comprise video images with a small change in the image content, thus ensuring a reliable location for image content
