This paper tries to clarify the retrieval and playback method considering temporal harmony. In this study, change points of the direction of object movement and the cycle of the motion are used as the accent points of a video clip. Beats are used as synchronization points of a music clip. The music measure is extracted in order to synchronize with the beat at the beginning of the measure. The synchronized...
In this study, we developed a thin plasmonic color sheet (TPCS) embedded with Al subwavelength gratings for use in flexible optical transmission filters, and experimentally demonstrated its transmission characteristics. Al subwavelength gratings were formed in a freestanding thin poly-para-xylylene (parylene-N) film less than 1-μm thick by using electron beam (EB) direct writing and sacrificial etching...
We developed a stretchable freestanding ultra-thin sheet composed by poly(styrene-butadiene-styrene) (SBS) and evaluated its optomechanical properties. The freestanding SBS sheet with a thickness of 675 nm was formed above a through hole of a PDMS sheet. Deflection of the freestanding sheet with a size of 10.4 mm × 10.4 mm was found to be 50 nm by optical surface profiler. In evaluation of the sheet...
This paper tries to obtain the speed of a video, where one or two objects and a background move with various speeds and in various directions. In this study, we measure their speeds by using the beats per minute (BPM). We find out the relationship of objects and a background through several experiments. In the case that only objects move, the average speed of objects becomes the speed of a video....
This paper focuses on temporal harmony of music and video clips. The method for producing a synchronized audiovisual material is proposed. Change points of the direction of the moving object are decided as synchronization points of video clips. The moving area of an object is extracted in order to detect the change points. Only the motion vectors in the area are used. The start point that an object...
In this study, we propose a flexible color filter based on surface plasmon using aluminum nanowire and nanodot array. Aluminum subwavelength lattice was formed on a parylene-N film and coated with parylene-N to avoid detachment from the substrate film. Both Al nanowire width of 250 nm and nanodot of 250 nm were successfully fabricated on the thin parylene-N film of 200 nm. Green color from the Al...
