The experiment shows that this method can powerfully denoise salt-and-pepper noise with good edge-preserving. 实验结果证明,这种方法不但能有效地滤除椒盐噪声,而且能够很好地保持边缘。 cjig.cn 2. Prepared in this experiment, a median filtering process, and salt and pepper noise generated by the im...
Together with an undercolor-removal process (59) in which a high-resolution black-component input to the half-toning process is significantly less than the minimum of the values of the color components throughout most of their range, this arrangement minimizes the salt-and-pepper noise that can...
1.However, salt & pepper noise occur during ima ge generation, communication and transformation, and affect image quality.为了消除图像上的椒盐噪声,并尽量保持图像的清晰度 ,提出了一种在中值滤波基础上 ,经过灰度直方图的分析 ,再采用合适的灰度级形态学运算去除图像中的椒盐噪声的新方法。 2.The median fi...
为了有效地去除数字图像中的椒盐噪声,提高图像质量,本文 在分析一些典型消除噪声方法的基础上,给出了一种新的椒盐噪声去除算法。首先,针对椒 盐噪声的特点,设计了一种基于动态窗口和邻域像素统计信息的噪声检测算法,有效地区分 了噪声点与非噪声,然后对检测出的噪声

Noise Adaptive Fuzzy Switching Median Filter for Salt-and-Pepper Noise Reduction This letter presents a novel two-stage noise adaptive fuzzy switching median (NAFSM) filter for salt-and-pepper noise detection and removal. Initially, the... Toh, K. K. V,Mat Isa, N. A - 《IEEE Signal Proce...
There is a significant recent advance in filtering of the salt-and-pepper noise for digital images. However, almost all recent schemes for filtering of this type of noise are not taking into an account the shape of objects (in particular edges) in images. We have applied the block-matching...
