We propose a fast and effective technique to improve sub-grid visual details of the grid based fluid simulation. Our method procedurally synthesizes the flow fields coming from the incompressible Navier-Stokes solver and the vorticity fields generated by vortex particle method for sub-grid turbulence. We are able to efficiently animate smoke which is highly(More)
We show how to create a music video automatically , using computable characteristics of video and music to promote coherent matching. We analyze the flow of both music and video, and then segment them into sequence with similar flow. Then, we match the segments using features extracted from the both video and music. To increase the structure of matching, we(More)
A hidden-picture puzzle contains objects hidden in a background image, in such a way that each object fits closely into a local region of the background. Our system converts image of the background and objects into line drawing, and then finds places in which to hide transformed versions of the objects using rotation-invariant shape context matching. During(More)
This paper introduces a way to generate or modify a melody using the editable noise function. The band-limited random numbers generated by the noise function are converted to the various property values of notes such as pitch and duration. Using this technique, we can modify an existing melody to produce new, similar melodies. The noise values can be(More)
We present a method for constructing 3D feature flow from video and its application to video stylization. Our method extracts smoothly aligned 3D vectors that describe the smallest variation of colors within a spatiotemporal video cube, and thus effectively preserves both spatial and temporal coherence in a relatively inexpensive manner. As an application(More)
Monodisperse spherical silica particles were synthesized by mixing 40 ml of aqueous ammonia (NH 4 OH, 28 wt%) with a solution containing 1000 ml of absolute ethanol (EtOH) and 80 ml of deionized water (H 2 O). After stirring for 30 min, 60 ml of TEOS (98%, Aldrich) was added to the solution and stirred for 6 h at room temperature. The as-synthesized silica(More)
We synchronize background music with a video by changing the timing of music, an approach that minimizes the damage to music data. Starting from a MIDI file and video data, feature points are extracted from both sources, paired, and then synchronized using dynamic programming to timescale the music. We also introduce the music graph, a directed graph that(More)
