| 摘要 | Systems and methods for digital video stabilization via constraint-based rotation smoothing are provided. Digital video data including a set of image frames having associated time stamps and a set of camera orientation data having associated time stamps may be provided. A smoothed set of camera orientation data may be generated by minimizing a rate of rotation between successive image frames while minimizing an amount of empty regions in a resulting set of smoothed image frames reoriented based on the smoothed set of camera orientation data. | ||

| 主权项 | 1. A computer implemented method comprising: providing, by a computer system, digital video data comprising a set of image frames having associated time stamps and a set of camera orientation data having associated time stamps, wherein the set of camera orientation data is based on an orientation of a camera during a capture of the digital video data by the camera; and generating, by the computer system, a smoothed set of camera orientation data by minimizing a rate of rotation between successive image frames while minimizing an amount of empty regions in a resulting set of smoothed image frames reoriented based on the smoothed set of camera orientation data. | ||
