CPC classification number: H04N5/2621 , G06T7/0002 , G06T13/80 , G06T2207/10016 , G06T2207/30168 , H04N5/23245 , H04N5/23254 , H04N5/23267
Abstract: Techniques and devices for creating an AutoLoop output video include performing postgate operations. The AutoLoop output video is created from a set of frames. After generating the AutoLoop output video based on a plurality of loop parameters and at least a portion of the frames, postgate operations determine one or more dynamism metrics based on a variability metric and a dynamic range metric for a plurality of pixels within the video loop. Postgate operations compare the dynamism metrics to one or more postgate threshold values and reject the video loop based on the comparison of the dynamism metrics to the postgate threshold values.
