python的图像处理模块 除了opencv专门用来进行图像处理,可以进行像素级、特征级、语义级、应用级的图像处理外,python中还有其他库用来进行简单的图像处理,比如图像的读入和保存、滤波、直方图均衡等简单的操作,下面对这些库进行详细的介绍。 目录 一、PIL库 一、安装命令 二、Image模块 三、format类 四、Mode类 五、co...

霍普菲尔德网络是第一个具有循环链接的神经网络,它是约翰·霍普菲尔德(John Hopfield)在《Neurons with graded response have collective computational properties like those of two-state neurons》中发明的。 受Hopfield 网络的启发,在《及时发现结构》中引入了全连接神经网络 – Elman 网络。 Elman 网络具有一个隐藏层...
