Abstract: Provided are video processing architectures and techniques configured to generate looping video. The video processing architectures and techniques automatically produce a looping video from a fixed-length video clip. Embodiments of the video processing architectures and techniques determine a lower-resolution version of the fixed-length video clip, and detect a presence of edges within image frames in the lower-resolution version. A pair of image frames having similar edges is identified as a pair of candidates for a transition point (i.e., a start frame and an end frame) at which the looping video can repeat. Using start and end frames having similar edges mitigates teleporting of objects displayed in the looping video. In some cases, teleporting during repeating is eliminated.

Abstract: A computing system transforms an input image into a stylized output image by applying first and second style features from a style exemplar. The input image is provided to a multimodal style-transfer network having a low-resolution-based stylization subnet and a high-resolution stylization subnet. The low-resolution-based stylization subnet is trained with low-resolution style exemplars to apply the first style feature. The high-resolution stylization subnet is trained with high-resolution style exemplars to apply the second style feature. The low-resolution-based stylization subnet generates an intermediate image by applying the first style feature from a low-resolution version of the style exemplar to first image data obtained from the input image. Second image data from the intermediate image is provided to the high-resolution stylization subnet.

Abstract: Systems and methods disclosed herein provide drawing assistance to a user that improves the user's ability to draw accurate perspective drawings. In general, a drawing assistance system provides a homography that annotates guidelines over an image and connects lined features of the image to a corresponding vanishing point. More specifically, the homography provides a perspective grid to the user that assists the user in adding drawing strokes to a drawing using the proper perspective. In addition, the drawing assistance system can adjust a user's drawing stroke to properly align with a vanishing point. Further, in some embodiments, the drawing assistance system allows a user to add an asset into a drawing such that the asset is displayed in the proper perspective, even after a user moves the asset within a drawing.
