Sharing digital media assets for presentation within an online social network
A method for reducing the number of images or the length of a video from a digital image collection using a social network, includes receiving a digital image collection captured by a user to be viewed by a viewer; wherein the viewer and the user are members of the same social network and using a processor to access the social network to determine a relationship between a viewer and the user. The method further includes using the processor to determine a set of summarization parameters based on the relationship between the viewer and the user and using the processor to reduce the number of images or the length of the video from the digital image collection using the determined set of summarization parameters to be viewed by the viewer.
1. A method for selecting and presenting digital video assets within an online social network, comprising:
receiving, from a user, digital video assets viewable by a viewer on the online social network, wherein the user and the viewer are members of the online social network;
using a computer processor to analyze video attributes of the digital video assets and a social distance between the user and the viewer in the online social network, wherein the digital video analysis comprises key frame determination;
using the computer processor to generate a video summarization for each of the digital video assets based on the digital video analysis and preset video summarization parameters, wherein the video summarization parameters comprise playback length of the video summarization;
using the computer processor to rank the video summarizations based on the social distance between the user and the viewer and based on one or more video attributes selected from the group consisting of: camera motion, camera fixation, and image quality;
using the computer processor to select a subset of the video summarizations in accordance with the ranking of the video summarizations; and
publishing the subset of the video summarizations within the online social networking environment for view by the viewer.
2. The method of claim 1 , wherein generating the video summarizations for each of the digital video assets comprises extracting snippets from the digital video assets and merging the snippets, wherein each snippet corresponds to a collection of video frames surrounding a highly ranked key frame.
3. The method of claim 2 , wherein highly ranked digital video assets are used to identify snippets corresponding to a collection of video frames surrounding highly ranked key frames.
4. The method of claim 2 , wherein the preset video summarization parameters further comprise minimum playback length of a snippet and the number of snippets contained in the video summarizations.
5. The method of claim 1 , wherein using the computer processor to analyze the social distance between the user and the viewer in the online social network comprises analyzing digital video assets provided by the viewer, analyzing groups of which the viewer is a member, and analyzing explicit tags by the user or the viewer that indicate interests of the viewer.
6. The method of claim 1 , wherein using the computer processor to analyze the social distance between the user and the viewer in the online social network comprises analyzing a social relationship between the user and the viewer, wherein the social relationship is selected from the group consisting of: relative, coworker, classmate, friend, membership in a common group, and attendee of activity of interest.
7. The method of claim 6 , wherein the activity of interest is selected from the group consisting of: a wedding, a party, a sporting event, and a live performance.
8. The method of claim 1 , wherein using the computer processor to analyze video attributes of the digital video assets further comprises using face detection and recognition algorithms to determine identities of individuals present in the digital video assets.
9. The method of claim 1 , wherein using the computer processor to analyze video attributes of the digital video assets further comprises using GPS data collected at capture time to estimate the location of a captured scene in the digital video assets.
10. The method of claim 1 , further comprising repeating the method of claim 1 for every viewer in the social network having a social distance to the user within a specific threshold.
11. The method of claim 1 , wherein the subset of the video summarizations is limited to a particular number based on the social distance between the user and the viewer.
