'How to find individual numbers in an image with Python OpenCV?
I have an image similar to the following. I want to separate two numbers 7 and 4 as shown in the image, in that I want to have a bounding box for each of these two objects.
How could I do this with OpenCV? I have no idea, how could I do this and was thinking if there is some way by using Sobel operator. The only thing that I tired was getting the Sobel.
s = cv2.Sobel(img, cv2.CV_64F,1,0,ksize=5)
but have no idea on how to proceed from here.

Follow the steps:
- Convert the image into grayscale.
- Use thresholding to convert image into a binary image, in your problem I think adaptive gausian will be most beneficial to use.
- Apply contour detection and then you can make bounding box around contours.
You may need to filter contours based on size or position.
