Multiple issues on latest version of OpenCV

[pyrusspangj]

Firstly I'd like to say, fascinating work by the looks of everything. I've been attempting to manipulate the code to work but it's not quite working.

Error 1: If running the code raw without any edits, the first error will appear on line 165: low = np.min(np.max(cnt, axis=1), axis=0), it will raise a NumPy AxisError; that axis 1 is out of bounds for array of dimension 0.
--> Changing the if statement right above it from "if len(contours) > 0:" to "if contours.ndim > 1:" will then create error 2.
Error 2: This error will occur on line 107 (line may vary depending on how much you modified the code at this point): contours = np.delete(contours, badBlob), it will raise a Value Error, indicating that "The requested array has an inhomogeneous shape after 1 dimensions".
--> Changing the deletion statement to contours = [contour for i, contour in enumerate(contours) if i not in badBlob] will then raise error 3.
Error 3: This error will occur during the program's first contour encounter, and will argue that the "isUpdated" boolean is not defined.
--> Simple fix, just write "isUpdated = False" on the line before the while loop.

Doing all of these adjustments will make the code run without error interruption, but will also fail to do its original job. As I saw from your example photos, I do not doubt at all the ability of the code to work properly, I would just like to know where you believe I went wrong in error handling and fixing.
Thank you so much!
