class StateManager(config: AppConfig)

Bases: object

Module to estimate people’s height

Parameters:

config (AppConfig) – configuration for the app

people_height_state = StateManager(config)

estimate_people_height(frames: List[Frame]) → None

Estimates people’s height from frames

Parameters:

frames (List[Frame]) – list of frames
