VIDEO STABILIZATION USING PADDED MARGIN PIXELS

摘要

One or more techniques and/or systems are provided for video stabilization and/or for image frame generation. For example, a user may instruct a video application hosted on a smart phone to capture a video at a target resolution of 1080 pixels. A padded input having a padded resolution that is larger than the target resolution may be obtained from a capture device, such as a camera of the smart phone. The padded input may be provided to a video stabilization component to obtain a target image frame having the target resolution. In this way, the video stabilization component may perform cropping using padded margin pixels (e.g., additional pixels of the padded input beyond the 1080 pixels of the target resolution) so that image upscaling after cropping (e.g., to account for global warping, etc.) may be mitigated to reduce blur that may otherwise result from image upscaling.

主权项

1. A method for video stabilization, comprising:
negotiating with a capture device to obtain a padded input, the padded input comprising padded margin pixels, the padded input having a padded resolution larger than a target resolution, the negotiating with the capture device comprising:
selecting a padded pixel percentage parameter based upon at least one of a cropping metric used by the video stabilization component, a field of view (FOV) of a sensor of the capture device, an amount of padding to be used by the video stabilization component, a set of available resolutions for the capture device, the target resolution, or an analysis of available computer resources of a computing device associated with the capture device; andinstructing the capture device to obtain the padded input based upon the padded pixel percentage parameter; and providing the padded input to a video stabilization component to obtain a target image frame having the target resolution.
