Abstract
Images may be extracted from a video. The images may be grouped into image groups. Numbers and types of classified visuals within the images may be detected. Individual types of classified visuals may correspond to individual classification weights. Image classification weights for the images may be determined based on the numbers and the types of classified visuals and the individual classification weights. Interest weights for the images may be determined based on the image classification weights and the sizes of the image groups to which the individual images belong. An interest curve may be generated based on the interest weights. A retime curve may be generated based on the interest curve. Time lapse images to be included in the time lapse video may be determined based on the images and the retime curve. The time lapse video may be generated based on the time lapse images.
