Generate image dataset from one folder, label each image one by one, for machine learning via tensorflow

This is an update for previous post.
http://lengerrong.blogspot.com/2017/04/create-your-own-dataset-for-machine.html

It is hard to collect enough images for your machine traning.
So I update this post to append images once you find some to your existed dataset.
All you need to do is copy your images to a folder and run the python script.

Of cause, you have to label each image while running the python script.
Below python script just have two label, 0 means cat, 1 means dog.
You can add more labels by just modify blue codes.

python show an image via subprocess.Popen

import tensorflow as tf
import Image
import os
import subprocess

def main(argv):
folder = argv[0]
if (len(argv) > 1):
    if tf.gfile.Exists(argv[1]):
      folder = argv[1]
    else:
      print ('%s not existed' % argv[1])
      return
else:
    print ("please input training image data folder path")
    return
for f in tf.gfile.ListDirectory(folder):
    filepath = os.path.join(folder, f)
    try:
      im = Image.open(filepath)
      p = subprocess.Popen(["display", filepath])
      label = raw_input("please label the image, 0 means cat, 1 means dog:")
      p.kill()
    except Exception, e:
      print (e)

python Thread.join & setDaemon sample

prototype:

join([timeout]) # wait the child thread complete

setDaemon(True) # once the daemon thread complete, the child thread complete too.

from threading import Thread
from PIL import Image

    class ImageThread(Thread):
      def __init__(self, filepath):
        Thread.__init__(self)
        self.filepath = filepath
        self.openresult = 0

      def run(self):
        try:
          im = Image.open(self.filepath)
          im.show()
          self.openresult = 1
        except Exception, e:
          print (e)

    imt = ImageThread('image.gif')
    imt.setDaemon(True) # should set before start
    imt.start()
    imt.join(10) # wait 10 seconds

Solution for no image display after call Image.show via python

simple python code like:

from PIL import Image
image = Image.open('image.gif')
image.show()

no image display while running on ubuntu system.

The easy solution is:
sudo apt-get install imagemagick
