Abstract: In various implementations a method includes obtaining a plurality of source images, stabilizing the plurality of source images to generate a plurality of stabilized images, and averaging the plurality of stabilized image to generate a synthetic long exposure image. In various implementations, stabilizing the plurality of source images includes: selecting one of the plurality of source images to serve as a reference frame; and registering others of the plurality of source images to the reference frame by applying a perspective transformation to others of the plurality of the source images.

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.
