polygon). It can carry out a variety of commonly used mathematical operations, commonly used filter operation, image measurements, as well as pixel statistics. It can carry on dem surface reconstruction and three-dimensional reconstruction of image sequences. And the framework is based around Python...
ImagePy_Learn | 图形学绘制代码学习:core\draw\polygonfill.py,最近在学图形学绘制,想到了ImagePy框架的ROI涂抹交互很方便,于是啃起了绘制代码。这里主要对ImagePy中一个填充工具进行难点讲解。让我们好好学习Python中的图形学绘制吧。例子代码来源:https://github.co
