We present a video editing technique based on changing the timelines of individual objects in video, which leaves them in their original places but puts them at different times. This allows the production of object-level slow motion effects, fast motion effects, or even time reversal. This is more flexible than simply applying such effects to whole frames,(More)
Polysaccharides were extracted from Lycium barbarum fruits in this work. Fourier transform infrared spectroscopy (FT-IR) and high-performance liquid chromatography (HPLC) have been employed to characterize this polysaccharides in the present study. The results of chemical composition indicated that the L. barbarum polysaccharides were composed of two kinds(More)
Depth-based view synthesis can produce novel realistic images of a scene by view warping and image inpainting. This paper presents a depth-based view synthesis approach performing pixel-level image inpainting. The proposed approach provides great flexibility in pixel manipulation and prevents random effects in texture propagation. By analyzing the process(More)
In this paper, we present an interactive static image composition approach, namely color retargeting, to flexibly represent time-varying color editing effect based on time-lapse video sequences. Instead of performing precise image matting or blending techniques, our approach treats the color composition as a pixel-level resampling problem. In order to both(More)
In this report, we propose a square lattice photonic crystal hetero-slab-edge microcavity design. In numerical simulations, three surface modes in this microcavity are investigated and optimized by tuning the slab-edge termination τ and gradual mirror layer. High simulated quality (Q) factor of 2.3 × 10(5) and small mode volume of 0.105 μm(3) are obtained(More)
