摘要 针对红外焦平面阵列图像成像系统中的准确、清晰、无失真的要求,提出了一种基于小波变换的图像边缘保护处理方法,重点分析了将图像的二维小波变换与统计学中的最大后验概率估计算法结合来进行图像消噪的处理方式,介绍了该方法在红外焦平面阵列图像中的应用。仿真实验表明,这种方法明显减轻了失真度,使图像更加清晰,有效的扼制了"人工虚影"现象。 An image edge-preserving disposal method using wavelet transform is presented and analyzed in detail. The method combines 2-D wavelet transform with maximum a posteriori estimation algorithm. The applieation of the method to the infrared focal plane Arrays image is described in order to meet the demands of accuracy, clarity, no distortion in the processing of image. The experimental results show that this method ease the image distortion, yoke the "artificial ghost" ,and make the image more clarity indeed.
