The intensity of pulse noisy pixels significantly differs from adjacent pixels of image. The de-noising will be accomplished by modifying the intensity of the noisy pixel according to the firing patterns of adjacent neurons of PCNN. At last, this dissertation suggests a new kind of filter for de-noising pulse noise based on the PCNN and median filter. It is very simple, and the simulation experiment of the image processing shows that the de-noising effect is much better than neighborhood averaging method and median filter.

一般脉冲噪声点与其所在图像像素灰度值之间相关性很差，而PCNN脉冲耦合神经网络能使相似神经元同步激发；这就决定亮点脉冲噪声像素对应神经元会在其区域所在相邻神经元中首先激发，为此结合中值滤波，我们提出了结合PCNN脉冲耦合神经网络和中值滤波的混合滤波新算法，理论分析和实验证明，该方案在滤除噪声的同时，比常规中值滤波更有效地保持了图像的高频细节信息。

The predictive coding is based on the relativity between the neighboring pixels. On the coutrary, steganograph will destroy the relativity between the neighboring pixels. Through computing and analysing the predictive error of cover image and steg image, it is obtained that steganograph will increase the predictive error. So the predictive error can be used to detect steganograph.

该算法的基本思想是利用空域隐写会破坏图像相邻像素之间的相关性，而预测编码是利用图像相邻像素之间的相关性来预测的，这样隐写后图像的预测误差将会大于载体图像的预则误差，通过计算隐写前后图像的预测误差来分析图像中是否含有秘密信息。
