Energy minimization is often the key point of solving problems in computer *** decades,many methods have been proposed(deterministic,stochastic,…).Some can only reach local minimum and others strong local minimum close to the optimal solution(global minimum).Since beginning of 21th century,minimization based on Graph theory have been generalized to find global minimum of multi-labeling problems. In this work,we study deterministic local minimization methods (Iterative Conditional Modes and Direct Descent Energy),and a stochastic global minimization with an improved Simulated Annealing algorithm.A new approach formulation to help local minimization to converge to a minimum closed to the global one is *** method combines local and global energy constraints in an multiresolution *** focus on stereo matching *** improved Simulated Annealing proved to reach global minimum as good as Graph based minimization methods. Promising results of proposed local minimization methods are obtained on Middlebury Stereo database compare to global methods.

Hand posture classification is a key problem for many human computer interaction ***,this is not a simple *** this paper,we propose to decompose the hand posture classification problem into 2 *** the first step,we detect skin regions using a very fast algorithm of color segmentation based on thresholding *** segmentation is robust to lighting condition thank to a step of color normalization using neural *** the second step, each skin region will be classified into one of hand posture class using Cascaded Adaboost *** contributions of this paper are:(i) By applying a step of color normalization,the posture classification rate is significantly improved under varying lighting condition;(ii) The cascaded Adaboost technique has been studied for the problem of face detection(2 classes).In this paper, it will be studied and evaluated in more detail in a problem of classification of hand postures(multi-classes).
