Adding attributes to the HandRegion class

[Trey-Daviz]

Hi guys! I've been diving deep into this project lately, but I've gotten a bit stuck when I try to expand upon it. Currently, I'm working on expanding it to not just recognize gestures, but to recognize a sequence (an array of gestures) like if I were to gesture one, two, three, four, five, it would be able to recognize that as "counting to five". I think that this has cool applications, but I hit a road block. When trying to add some attributes to hand region to make this compatible to how I want to do this, I only see the docstring for hand_region. The init doesn't even initialize hand.gesture. It's weird enough to not initialize anything, but I can't even find declarations for these attributes inside of the class. Where can I find your attribute declarations so that I can continue modifying the code to work for my purposes? For reference of my current skill level, I am well versed in coding, but machine learning is a new subject for me.

Hi, the 'gesture' attribute is set in the recognize_gesture() function of file mediapipe_utils.py (only when the argument 'use_gesture' of HandTracker* class is set to True).

I will add the missing comment in the HandRegion docstring.

I saw that, but it still doesn't make sense to me.

This line of code:
if self.use_gesture: mpu.recognize_gesture(hand)
is what calls recognize_gesture.

It checks if use_gesture is true, and if it is, it starts trying to recognize the gesture. However, that doesn't explain where gesture is declared. That's where gesture is initialized. I use hand.gesture often in my coding, but I can not seem to find where I can add a new attribute to the Hand Region class.

I am not sure to get your point. You know that in python, you don't need to declare variables or class attributes ? If you want to add new attributes to the HandRegion class, you can do it wherever you want (no need to declare or even initialize the attribute in the init()).
