Using Python and OpenCv to sequentially display all the images in a directory

Question

I'm trying to use OpenCV's python bindings to sequentially display all of the images in a directory.

This code prints all the files in my directory but only displays the first image it opens:

for file in os.listdir(path):
  print(file)

  image = cv2.imread(os.path.join(my_dir, 'attachments',
  file))

  cv2.imshow("Image", image)
  cv2.waitKey(550)

What do I need to change so that every image in my directory is displayed by cv2.imshow? My print statement shows me that I am looping through all of my images but imshow is not being redrawn through any but the first iteration of my loop.

Answer 1

EDIT:

If you want to see all your images in different windows:

The other thing that occurred to me is that you may want to give each of your cv2.imshow() commands a different name other than "Image". With different names, you can have multiple imshow windows. So you could do:

for indx, f in enumerate(os.listdir(path), start=1):
    image = cv2.imread(os.path.join(my_dir, 'attachments', f))  
    cv2.imshow("Image-{}".format(indx), image)
    cv2.waitKey(600)

EDIT 2:

I went back to double check my answer and realized that your code seems to work just fine for me... I'm using opencv '3.0.0'
