【摘要】 本文研究用多分辨率分析去除光斑图像中噪声的方法．对一幅模拟的受到噪声污染的激光斑图像进行了处理分析，去噪后图像信噪比明显优于去噪前，且光斑主要特征参数更接近模拟的光斑参数．更多还原

【Abstract】 We study the method of using MRA in order to remove noise. From the result of processing for a spot image contadrinated by noise, Signal-Noise Ratio increases greatly, comparing with ideal caset the main characteristic parameters are almostly consistent .The method has a practical value in the problem of removing noise of laser spot’s image.更多还原
