摘要
噪声是影响图像质量的重要因素,噪声的存在导致图像的某些特征细节不能被辨识,图像的信噪比下降。从图像的视觉效果,其后续处理以及识别的角度来说,对图像去噪是很有必要的。本文提出了一种基于小波变换与数学形态学结合的彩色图像去噪算法,直接在彩色空间中对彩色图像进行去噪。实验表明这种算法是可行的、有效的。
The noise is an important factor affecting image quality, the presence of noise, leading to some features of the image detail that can not be identified, the image signal to noise ratio decreased. It is very necessary that the denoising for the image visual effects, follow-up processing, and identify. This paper presents a wavelet transform and mathematical morphology based on combination of color image denoising algorithms, directly in the color space for color image denoising. Tests show that the algorithm is feasible and effective.
