Abstract
Interpolating frames of a video may provide a technique for one or more of frame rate conversion, temporal upsampling for generating slow motion video, image morphing, virtual view synthesis, and/or other video applications. A system may be configured to interpolated frames of a video by leveraging frequency domain representations of individual frames. The frequency domain representations may be decomposed into set of discrete functions that make up the frequency domain representations. Corresponding functions from sets of functions associated with frames with which an interpolated frame is to be determined may be identified. Phase differences between corresponding functions may be determined. Interpolated functions between the corresponding functions may be determined based on the determined phased differences. Information describing spatial domain representations of interpolated frames may be determined based on the interpolated functions.
