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...
