In this paper, we propose a tree based regression algorithm, (TREG) that addresses the problem of data compression in wireless sensor networks. By function approximation based on multivariable polynomial regression and passing only the coefficients returned by the regression function instead of aggregated data, TREG achieves the following goals: (1) the(More)
Contrast Enhancement involves enhancement of images such that the visibility of images increases. Contrast enhancement of images is used for a variety of applications such as in medical field, image enhances software's. Although there are various techniques implemented for the enhancement of images such as using non-dynamic stochastic resonance [1].(More)
