Adaptive luminance coding-based scene-change detection for frame rate up-conversion

This paper presents a new scene-change detection method that uses adaptive luminance coding for frame rate up-conversion. The proposed scene-change detection method splits a frame into several blocks and converts the gray levels of pixels in each block to bit codes. Then, it computes the difference between the bit codes in previous and current blocks. In addition, directional distribution analysis is applied to correct the areas falsely detected as a scene change. The experimental results show that the average F₁ score of the proposed method was up to 0.479 higher than those of the benchmark methods (a 108.53% improvement). The proposed method also reduced the average computation time per pixel by up to 5.572 μs compared to the benchmark methods (a 73.14% reduction).
