摘要：侧抑制网络具有突出边框、增强反差的作用,但抗噪性差。其在增强图像的同时,噪声点也相应地得到了增强,这对后续处理十分不利。构造一个可能性度量因子,用来判定某一突变是噪声的突变还是有效信号的突变,将该因子引入到侧抑制网络中,使侧抑制网络具有一定的抗噪能力。改进后的网络既保留了原有网络的增强功能,又添加了抗噪性能。对改进后的网络进行理论分析和实验仿真表明:该网络在图像增强的同时对噪声具有一定的抑制作用。
The lateral inhibition network has the function of standing out the frame and enhancing the contrast, but the antinoise capability is poor. When using it, the noisy pixel dot is also enhanced. This is disadvantageous for the following process. In this paper, a probable measure coefficient is constructed to judge which break it belongs to, the noise break or the effective single break. The lateral inhibition has a certain antinoise capability by introducing this coefficient. The promoted network has both enhanced and antinoise capability. Both theory analyzing and experimentation emulating show that the noise can be inhibited to a certain extent with the new method.
