SocialDistancing Objects

class SocialDistancing(Element)

Apply the social distancing algorithm to the list of detections.

Attributes:

• name str - The name of the element.
• threshold float - The object nearness threshold {value between 0-1}.

Examples:

ele = SocialDistancing()

extract_params

@staticmethod
def extract_params(model_params)

Extract the parameters for this element.

Arguments:

• model_params List[str] - The parameters for this element.

Returns:

• threshold float - The object nearness threshold {value between 0-1}.

Raises:

• ExtractParameterException - If the parameters are not valid.

Examples:

params = SocialDistancing.extract_params(["0.2"])
ele = SocialDistancing(*params)

process

def process(meta)

Process the bounding boxes.

This is the main function for this element. It will take the bounding boxes and calculates distance between every object and flags if the distance is less than the threshold.

Arguments:

• meta dict - The metadata to process.

Returns:

• meta dict - The processed metadata.

Examples:

ele = SocialDistancing()
meta = ele.process(meta)
