摘要: 采用FFT变换实现单帧图像上行采样, 对实现策略进行了改进, 即通过对整幅图像的分块处理提高算法的执行效率, 并对分块处理的效率与整幅处理的效率进行比较.

关键词: 上行采样, 插值, 超分辨率

Abstract: The upsampling of a single frame is realized by means of FFT. The realizing strategy is improved, i.e., the block-based treatment of full images is adopted so as to raise the implementing efficiency of the algorithm. The efficiency of the block-based treatment is compared with that of the full-image treatment.

Key words: upsampling, interpolation, superresolution
