一种改进的夜间数字监控图像的去噪算法

本文针对夜间数字监控图像存在大量噪声的情况,比较了各种常见的去噪算法,在综合考虑了图像去噪平滑效果、图像的清晰程度及图像去噪时间复杂度的基础上,提出了形态学方法和中值滤波方法相结合的图像去噪算法。通过图像去噪前后效果对比验证了该算法的可行性。

An Improved Denoising Algorithm for The Night Digital Monitor Image

For the night digital monitor image of many noises the common denoising algorithms are compared, and the enhanced denoising method is designed combining morphology with median filter after balancing image smoothness, clearness and time complexity. The expriments confirm that the algorithm is feasible by the contrast of the effect of before and after denoising.
