封装好的Harris算子提取特征点、匹配、提粗匹配类，添加到个人工程即可调用使用（基于opencv2）.-Operators packaged Harris feature point extraction, matching, mention rough matching class, adding to the personal project can be called using (based on opencv2).
本文实例为大家分享了python多进程读图提取特征存npy的具体代码，供大家参考，具体内容如下
import multiprocessing
import os, time, random
import numpy as np
import cv2
import os
import sys
from time import ctime
import tensorflow as tf
image_dir = rD:/sxl/处理图片/汉字分类/train10/ #图像文件夹路径
