Abstract

Image processing thresholding algorithms are very extended segmentation tools for tracking applications. The centroid of the tracked image distribution use to be a good point of reference for locating it. In this work we show a new thresholding technique which is based in the estimation of the optimum threshold value for achieving the minimal variance in the calculated centroid for the processed image. One experience was done for evaluating its performance qualities. The direct extension of these results to Shack- Hartmann wave-front sensors advantages and possibilities of application of this technique.
