Django or Flask or possibly none!, for an API based Website for object detection in images?

as a self learned programmer who is fairly familiar with python, I'm trying to develop a website which has an API for object detection in an image, i was wondering should I use Django or Flask or they are a bit overkill for this task, what do you suggest for front end development, can i do it also in these frameworks. I'm trying to keep whole project in python as far as possible. so what so you guys think, any suggestions?
