Consisting of motion estimation and motion compensated interpolation, the performance of frame rate upconversion highly depends on the motion estimation method it uses. This paper evaluates the performance-complexity trade-offs of the phase correlation method for motion estimation, obtained for various ratio of the number of candidate peaks to the number of total peaks. In addition, this paper presents a phase correlation method that uses variable block sizes. In experimental results, the proposed method outperformed other benchmarks in terms of the performance over complexity.
