In this paper, we present a real-time sports analysis system, which not only recognizes the semantic events, but also concludes the behavior, like player’s tactics. To this end, we propose an advanced multiple-player tracking algorithm, which addresses two improvements on practical problems: (1) updating of the player template so that it remains a good model over time, and (2) adaptive scaling ...

In this study, a simple and effective method for the detection of trace amounts of arsenic in water samples was developed. Arsenic hydride generated by the reduction of a water sample was passed through a sensing filter retaining silver bis(2-ethylhexyl)dithiocarbamate complex. The original yellow color of the filter immediately turned reddish violet. The difference of color was observed by a r...

A new kind of particle filter is proposed for the state estimation of nonlinear system. The proposed algorithm based on Quadrature Kalman Filter by using integral pruning factor, which optimizes and reorganizes the integration point. New algorithm overcomes the particle degeneration phenomenon well by using Pruning Quadrature Kalman Filter to produce optimized proposal distribution function. In...

Natural images in the colour space Y UV have been observed to have a non-Gaussian, heavy tailed distribution (called ’sparse’) when the filter

Whether categorical perception of color is lateralized in the left cerebral hemisphere (e.g., Gilbert, Regier, Kay, & Ivry, 2006) or not (e.g., Witzel & Gegenfurtner, 2011) is still controversial. This ongoing debate, however, has been studied with visual search tasks, which seemed to produce residual laterality effects. The present study assessed whether a delayed discrimination task with divi...

In this paper a new algorithm to obtain a continuous tone image starting from a halftoned one is proposed. This descreening technique is based on Butterworth filtering in the frequency domain. It removes the pattern of the original screen leaving unchanged the colors in the image. The proposed algorithm ensures fast and effective results, and can be used also by non-qualified operators.

Robust real-time tracking of non-rigid objects is a challenging task. Particle filtering has proven very successful for non-linear and nonGaussian estimation problems. The article presents the integration of color distributions into particle filtering, which has typically been used in combination with edge-based image features. Color distributions are applied, as they are robust to partial occl...
