iris.nodes.encoder.iris_encoder module

class iris.nodes.encoder.iris_encoder.IrisEncoder(mask_threshold: float = 0.9, callbacks: List[Callback] = [])

Bases: Algorithm

Binarize IrisFilterResponse to generate iris code using Daugman’s method.

Algorithm steps:

1. Binarize iris response by comparing real and imaginary parts to zero.

2. Binarize mask response by comparing real and imaginary parts to a given parameter: mask_threshold.

mask_threshold: float

run(response: IrisFilterResponse) → IrisTemplate

Encode iris code and mask code.

Parameters:

response (IrisFilterResponse) – Filter responses.

Returns:

Final iris template.

Return type:

IrisTemplate
