Frame Interpolation Using Phase Information and Guided Image Filtering

Videos with low frame rate lacks the visual quality element and unable to meet the standards of new multimedia systems. In this paper, a technique for frame interpolation utilizing phase information is proposed. Phase information gives the intuition that the motion of signals can be depicted as a phase shift. The two consecutive input frames of video are passed through a guided filter to preserve edges of objects in frames. These frames then decompose into multi scale pyramid and the difference in each pixel is calculated to compute the phase difference which then used to interpolate the in-between frame. The proposed technique can be used to increase the frame rate of videos. Subjective and objective comparison is performed with the state of art existing technique to prove the significance of proposed technique.
