Loading images with OpenCV and imageio

- [Instructor] My faces.py script solution…is organized into two functions.…The detect faces function, that begins on line 10,…is the real meat of this program.…It takes an image path as the input argument,…performs the facial detection,…and returns the json output data.…I've included an optional display argument…to control whether or not the program…displays an image with boxes around the detected faces.…Scrolling down, on line 51, is the main function…that gets called when this script is executed…as a top level module.…

On lines 54 to 61, I use the Tkinter module…to create a file dialogue box…asking the user to choose an image to analyze.…The withdraw method, on line 54,…hides the Tk window that gets created,…so the user only sees the popup dialogue box.…That open file dialogue returns a path…to the selected image file, which I then pass…to the detect faces function on line 61.…I chose to set that display flag to True…because I like seeing the images with detection boxes.…

The output from the detect faces function…
