Patent ID: 8869198

Claim:
A computer-assisted method for producing a space time summary for one or more original videos, comprising: automatically recognizing a key element in an original video by a computer processor, wherein the original video comprises a series of video frames, wherein the key element occupies of a portion of at least one of the video frames in the original video, wherein the step of automatically recognizing a key element in an original video comprises: selecting a complex element comprising at least two elements from an original video; segmenting the complex element from the original video; extracting data feature vectors from the at least two elements by the computer processor; matching the data feature vectors to reference feature vectors that are associated with a common feature descriptor; and automatically recognizing at least one of the two elements as the key element; extracting pixels from the portions related to the key element in the series of video frames of the original video, wherein the step of extracting pixels from the portions includes extracting the complex element from the original video to form part of the video bit, wherein the portion of the video frames related to the key element dynamically change positions in the video frames of the original video; producing a video bit comprising a series of video frames comprising the pixels and audio information extracted from the original video, wherein at least one video frame of the video bit is formed by a subset of pixels of the corresponding video frame in the original video; automatically displaying a plurality of video bits in a user interface, wherein the plurality of video bits are extracted from one or more original videos, and provide a space time summary for the one or more original videos; and allowing at least two of the plurality of video bits to be played simultaneously with audio and in motion in the user interface.
