提出了一类新的两阶段方法来去除椒盐噪声.第一阶段,利用经典的自适应中值滤波器辨别出被噪音污染的像素点;第二阶段,利用一种自适应有限冲激响应(FIR)滤波器恢复第一阶段辨别出的污染像素点.算法保留了自适应中值滤波的低计算复杂度.计算机模拟表明该算法是可行的.
A new two-stage method is proposed to remove the salt-pepper noise. In the first stage, classical adaptive median filter is used to identify pixels contaminated by noise. In the second stage, an adaptive finite impulse response FIR filter to recover the contaminated pixels identified in the first stage.The algorithm retains the low computational complexity of adaptive median filtering.Computer simulations show that this algorithm is feasible.
