传统处理方法

一、传统操作

传统操作方法为新增，用于一些网络最后仅返回单通道图像或在网络计算中需要，因此需要使用一些基本方法进行预处理或后处理，目前此处暂未分离，统一放于ppcd.traditions下，后期将分为预处理和后处理操作。

方法 简介
CVA 计算两期图像的变化矢量
BaseCompute 对两期图像进行做差/除运算
MRF 将原图和预测图输入马尔科夫随机场进行分割后处理

这里的传统操作主要用来辅助训练和预测，后期将分为预处理和后处理两部分操作。

PdRSCD（PaddlePaddle Remote Sensing Change Detection）是一个基于飞桨PaddlePaddle的遥感变化检测的项目，pypi包名为ppcd。目前0.2版本，最新支持图像列表输入的训练和预测，如多期影像、多源影像甚至多期多源影像。可以快速完成分割、变化检测等任务。
