Abstract
An image processing method comprises: clustering images of a set of images to generate a plurality of scenes each comprising an unordered cluster of images; ordering images within scenes respective to video coherence to generate ordered scenes comprising ordered sequences of images; and generating video content as images ordered in accordance with the ordered sequences of images comprising the scenes. In some embodiments, the video content is converted to video comprising video frames played at a predetermined frame rate.
Claims19
An image processing method comprising:
- clustering images of a set of images to generate a plurality of scenes each comprising an unordered cluster of images wherein the clustering is based on pairwise comparisons between pairs of images of the set of images;
- ordering images within scenes respective to video coherence to generate ordered scenes comprising ordered sequences of images;
- and
- generating video content as images ordered in accordance with the ordered sequences of images comprising the scenes;
- wherein at least the clustering and the ordering are performed by a digital processor.
An image processing method comprising:
- clustering images of a set of images to generate a plurality of scenes each comprising an unordered cluster of images;
- ordering images within scenes respective to video coherence to generate ordered scenes comprising ordered sequences of images;
- generating video content as images ordered in accordance with the ordered sequences of images comprising the scenes;
- selecting a display time for each image;
- and
- generating video comprising video frames based on the video content wherein each image of the video content defines one or more video frames effective to cause the image to be displayed for the determined display time when the video is played at a predetermined frame rate;
- wherein at least the clustering and the ordering are performed by a digital processor.
A non-transitory storage medium storing instructions executable by a digital processor to perform an image processing method comprising clustering images of a set of images to generate a plurality of scenes and ordering images within each scene respective to a video coherence criterion, wherein the video coherence criterion comprises an estimation of a shortest path through the images within the scene wherein the estimation employs a pairwise image comparison measure.
An image processing method comprising:
- automatically ordering a set of images based on a video coherence criterion comprising a shortest distance estimation wherein the automatic ordering comprises clustering the set of images to generate clusters defining a plurality of scenes and automatically ordering the images within each scene based on the video coherence criterion;
- and
- playing the images as video comprising frames defined by the ordered set of images and played at a predetermined frame rate.
An image processing method comprising:
- automatically ordering a set of images based on a video coherence criterion;
- playing the images as video comprising frames defined by the ordered set of images and played at a predetermined frame rate;
- and
- selecting the predetermined frame rate using a constant entropy criterion.
