摘要
为了在增强滤波器去噪强度的同时还能够保留更多的图像边缘细节信息,提出了将相位一致性原理同传统双边滤波器相结合的改进算法。根据提取图像的相位一致性信息,自适应修改双边滤波器的空间相关性和灰度相关性因子,以取得最佳的滤波效果。通过实验图像进行验证,并对处理后的图像进行了主客观还原效果评价,峰值信噪比和结构相似性指数均有较大的提升,实验结果表明了该算法的有效性和可行性。
To enhance the filtering performance while preserving more edges and details information,a novel method combined with phase congruency and traditional bilateral filter method is put forward.According to the phase congruency information of image,the bilateral filter's space correlation and gray correlation factors are modified adaptively to obtain the best filtering effect.By processing the noised images with proposed method and evaluating the processing effect subjectively and objectively,the peak signal to noise ratio(PSNR)and structure similarity(SSIM)index are significantly improved.The effectiveness and feasibility of the algorithm are demonstrated in practice.
