    摘要: A method generates a summary of a video. Faces are detected in a plurality of frames of the video. The frames are classified according to a number of faces detected in each frame and the video is partitioned into segments according to the classifications to produce a summary of the video. For each frame classified as having a single detected face, one or more characteristics of the face is determined. The frames are labeled according to the characteristics to produce labeled clusters and the segments are partitioned into sub-segments according to the labeled clusters.

    摘要: A method plays frames of a video adaptively according to a visual complexity of the video. First a spatial frequency of pixel within frames of the video is measured, as well as a temporal velocity of corresponding pixels between frames of the video. The spatial frequency is multiplied by the temporal velocity to obtain a measure of the visual complexity of the frames of the video. The frames of the video are then played at a speed that corresponds to the visual complexity.

    摘要: A method summarizes a video including a sequence of frames. The video is partitioned into segments of frames, and faces are detected in the frames of the segments. Features of the frames including the faces are extracted. For each segment including the faces, a representative frame based on the features is selected. For each possible pair of representative frames, distances are determined based on the faces. The distances are arranged in a matrix. Spectral clustering is applied to the matrix to determine an optimal number of clusters. Then, the video can be summarized according to the optimal number of clusters.

    摘要: A method plays back a video at speeds adapted to content of the video. A video is partitioned into summary segments and skipped segments. The summary segments are played back sequentially at a normal play back speed, and the skipped segments are played back at varying speeds corresponding to a visual complexity of the skipped segments.
