Personally, I've always used OpenCV with all object detection and object recognition tasks I've worked on to take advantage of the many CV functions it provides. So it was only natural for me to use OpenCV since it wouldn't require an additional dependency like Pillow.
I could've definitely used Pillow, but is there any tangible advantage to using Pillow over OpenCV?
