粒子群算法是求解函数优化问题的一种新的进化算法，然而它在求解高维函数时容易陷入局部最优，为了克服这个缺点，提出了一种新的粒子群算法，算法对粒子的速度和位置更新公式进行了改进，使粒子在其最有位置的基础上进行位置更新，增强了算法的寻优(PSO for solving function optimization problems is a new evolutionary algorithm, but it is easy to solve high-dimensional function into local optimum, in order to overcome this shortcoming, a new particle swarm algorithm, algorithm on the particle velocity and location of the update formula has been improved, so that particles in the most positions on the basis of location updates, enhancements, optimization algorithm)

matlab code fitting weibull distributions MLE

The most widely used transform for image fusion at multi scale is Wavelet Transform since it minimizes structural distortions. But, wavelet transform suffers lack of shift invariance & poor directionality. These disadvantages are overcome by using our proposed method that is Un-decimated Discrete Wavelet Transform.
