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 ...

Similarly, a DigitalMicrograph stack of size 100 x 20 x 10 is represented by a NumPy array of shape (10, 20, 100). Updating image data NumPy arrays connected to DigitalMicrograph images directly address the same memory space. When using a Python script to change these values, one has to...
