The spatiotemporal spectra of a video that contains a moving object form a plane in the 3D frequency domain. This plane, which is described as the theoretical motion plane, reflects the velocity of the moving objects, which is calculated from the slope. However, if the resolution of the frequency analysis method is not high enough to obtain actual spectra… (More)

The spatiotemporal spectra of a movie that contains a moving object form a plane in the three-dimensional (3-D) frequency domain. This plane, which is referred to as the theoretical motion plane, reflects the velocity and calculating the slope of the moving objects. However, if the resolution of the frequency analysis method is not high enough to obtain the… (More)

A movie may be represented as a three-dimensional (3-D) signal and as a spatiotemporal spectrum in a 3-D frequency domain. Most spatiotemporal spectra lie on a theoretical motion plane when an object moves at a uniform velocity in a movie. By calculating the slope of this plane, we can estimate the velocity of the moving object. However, the spa-tiotemporal… (More)

The spatiotemporal spectra of a video that contains a moving object form a plane in the three-dimensional (3D) frequency domain. This plane, which is referred to as the theoretical motion plane, reflects the velocity, which is calculated from the slope, of the moving objects. In the present paper, we propose a high-resolution frequency analysis method,… (More)

In this paper, metal press-together contacts for electric interconnection between free-standing polymer microfluidic substrates is presented. In previous work, we have demonstrated fabrication and mechanical assembly and fluidic pressurization of interlocking SU-8 chip-to-chip connections. The addition of electronic routing to the microfluidic polymer chips… (More)
