labelImg操作麻烦，用opencv写了个假的，勉强能用
LabelImage.py:

你要用的.py里面这样写：
1 import cv2 2 from LabelImage import MakeLabel 3 4 yourPresentImageNumberWaitForProcess = 0 5 yourImageSizeWhatYouWantToScale = (640, 480) 6 yourLabelList = ["cat", "dog"] 7 8 yourRoot = "path/to/your/root" 9 yourTrain = "path/to/your/train" 10 yourVal = "path/to/your/val" 11 12 yourObj = MakeLabel(winName="your windows name", 13 presentImage=yourPresentImageNumberWaitForProcess, 14 resize=yourImageSizeWhatYouWantToScale, 15 label=yourLabelList, 16 root=yourRoot, 17 train=yourTrain, 18 val=yourVal) 19 20 pathOfOriginImage = "D:/path/to/your/images/which/wait/for/process" # /process is a directory, pictures is /process/n_n.jpg 21 yourObj.setFont(cv2.FONT_HERSHEY_DUPLEX) # 可写可不写 22 yourObj.view(pathOfOriginImage)
使用方法：
首先点击运行就进去了，然后鼠标左键开始画框，然后画完按"n"下一个标签（next），所有的标签都画完之后，按“k”保存，自动跳到下一张图片，
如果有废片也可以按鼠标右键跳过，
注意：要shift切换成 ‘英’ 文输入法才能按键盘
如果你画了100张（0-99）就去吃饭去了，回来的时候可以把
yourPresentImageNumberWaitForProcess = 0
presentImage=yourPresentImageNumberWaitForProcess
设置为100，这样就从第101张开始了
亲测有效：
但是有个缺点是每张图片都要包含所有类。。。今天没时间改了，改天有时间再来完善
