Gestures are a natural and effective altenative to command mobile robots. This paper describes an online visual recognition system to recognize a set of 5 dynamic gestures executed with the user’s right hand and oriented to command mobile robots. The system employs a radial scan segmentation algorithm combined with a statistical-based skin detection method to find the candidate face of the user...

The simple Bayesian classiier (SBC), sometimes called Naive-Bayes, is built based on a conditional independence model of each attribute given the class. The model was previously shown to be surprisingly robust to obvious violations of this independence assumption, yielding accurate classiication models even when there are clear conditional dependencies. The SBC can serve as an excellent tool fo...

We propose a Markov chain Monte Carlo-based deconvolution method designed to estimate the number of peaks in spectral data, along with optimal parameters each radial basis function. Assuming cases where is unknown, and sweep simulation on all candidate models computationally unrealistic, proposed efficiently searches over probable candidates via trans-dimensional moves assisted by annealing eff...
