Automatic spin measurements for pitched Baseballs via consumer-grade high-speed cameras
Controlling the spin of a ball is important in a variety of sports, especially baseball. For an athlete to properly train, it is necessary to know spin information immediately after throwing or hitting a baseb...

Cadzow Denoising Upgraded: A New Projection Method for the Recovery of Dirac Pulses from Noisy Linear Measurements
We consider the recovery of a finite stream of Dirac pulses at nonuniform locations, from noisy lowpass-filtered samples. We show that maximum-likelihood estimation of the unknown parameters amounts to a diffi...

Sampling and Recovery of Continuously-Defined Sparse Signals and Its Applications
The common guideline for sampling continuously-defined signals has been provided by the Nyquist frequency for long. Recently it was clarified that even though signals in radar, echo, and sonar are wide-band wi...

Optimal Design of Optical Filter for White Light Interferometry based on Sampling Theory
Vertical-scanning white light interferometry is a technique of profiling the surface topography of objects such as semiconductors, liquid crystal displays (LCDs), and so on. The profile is given by the “square...

Sampling Theorem with Optimum Noise Suppression
We propose sampling theorems that reconstruct the optimal approximation under a certain criterion from a finite number of degraded, noisy, sampled values. In that criterion, we minimize the average difference bet...

Signal Reconstruction by Projection Filter with Preservation of Preferential Components
Signal reconstruction is one of the knowledge extration problems. Especially in this problem, knowledge means underlying signal or image, which is extracted from the downsampled one. In this paper, we propose ...
