Argument	Type	Default	Description
region	list	[(20, 400), (1080, 400), (1080, 360), (20, 360)]	Defines the region points for object counting, queue monitoring, trackzone or speed estimation. The points are defined as coordinates forming a polygonal area for analysis.
show_in	bool	True	Indicates whether to display objects that are counted as entering the defined region. Essential for real-world analytics, such as monitoring ingress trends.
show_out	bool	True	Indicates whether to display objects that are counted as exiting the defined region. Useful for applications requiring egress tracking and analytics.
colormap	int or tuple	COLORMAP_PARULA	Specifies the OpenCV-supported colormap for heatmap visualization. Default is COLORMAP_PARULA, but other colormaps can be used for different visualization preferences.
up_angle	float	145.0	Angle threshold for detecting the "up" position in workouts monitoring. Can be adjusted based on the position of keypoints for different exercises.
down_angle	float	90.0	Angle threshold for detecting the "down" position in workouts monitoring. Adjust this based on keypoint positions for specific exercises.
kpts	list	[6, 8, 10]	List of keypoints used for monitoring workouts. These keypoints correspond to body joints or parts, such as shoulders, elbows, and wrists, for exercises like push-ups, pull-ups, squats, ab-workouts.
analytics_type	str	line	Specifies the type of analytics visualization to generate. Options include "line", "pie", "bar", or "area". The default is "line" for trend visualization.
json_file	str	None	Path to the JSON file defining regions for parking systems or similar applications. Enables flexible configuration of analysis areas.
