遗传算法在小波阈值变换图像去噪中的应用

在岩层图像获取和传输过程中会受到来自传感器震荡、电子元器件干扰等因素的影响,导致图像质量下降。小波阈值去噪技术早已体现出它在图像去噪上的优越性,而阈值函数的选取特别是阈值的确定是小波去噪技术的关键所在,本文结合遗传算法以期找到相对最优阈值,应用结果证明遗传算法在此方面的可行性较好。

In the process of strata image acquisition and transmission,It will be interferenced from many factors such as sensor concussion,electronic components and so on,lead to the decrease of the quality of the image . Wavelet threshold denoising technology already reflect the superiority of it on image denoising,Especially for selecting threshold function is to determine the threshold of wavelet denoising technology. Based on genetic algorithm to find the relative optimal threshold is our target,Application results show the feasibility of the genetic algorithm in it well.
