均方误差控制步长恒模医学CT图像盲均衡算法
Research of variable step-size constant modulus medical CT image blind equalization algorithm based on mean square error
摘要
Abstract
A novel adaptive variable step-size constant module medical CT image blind equalization algorithm is proposed. The process of image restoration transformed by a linear operation is equivalent to one dimensional blind equalization.The constant modulus blind equalization cost function applied to medical CT image is foundedThe mean square error is utilized as step-size control factor to speed up the convergence and improve the performance of the algorithm.Computer simulations show that new algorithm improves peak signal to noise ratio, restoration effects and efficiency of operations, and speeds up the convergence speed.关键词
