The algorithm sets the range of noise pixels based on the characteristics of salt and pepper noise. 该算法根据椒盐噪声的特点,确定了准噪声点的范围; xuebao.sdju.edu.cn 8. It has proved that this algorithm can not only effectively remove salt and pepper noise, but also protect the details. 实...
椒盐噪声是指两种噪声,一种是盐噪声(salt noise)盐 = 白色(255),另一种是胡椒噪声(pepper noise)椒 = 黑色(0)。前者是高灰度噪声,后者属于低灰度噪声。一般两种噪声同时出现,呈现在图像上就是黑白杂点。 对于彩色图像,也有可能表现为在单个像素BGR三个通道同时随机出现的255或0,也是模拟的原理。 源代码 #incl...

Most computer vision applications such as object detection and edge detection are heavily influenced by the presence of noise. The presence of noise mandates pre-processing. Determining the noise level (whether high or low) is a demanding field in current times. Salt and pepper noise is the ...

加糖的话心情一下就好了，加盐和加沙子感觉差不多。
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
