Detailed Description

Overrides for the validation parameters.

Affects the face detection and validation process. More relaxed values can decrease the number of images being marked as invalid, but the accuracy will degrade for such images.

detectable_face_size_relative

Optional<float> idliveface::CustomValidationParameters::detectable_face_size_relative

Minimal relative face's width and height for the face to be detected.

Acts similar to the min_face_size_relative, but if the face box is too small, the face is just being skipped. It is used to filter the small faces in the background.

min_face_size_relative

Optional<float> idliveface::CustomValidationParameters::min_face_size_relative

Minimal relative face's width and height.

It's a ratio of the face's width and height to the image's width and height. Represented as a value between 0 and 1. For example, if the value is 0.25, each side of the face box should be at least a quarter of the image's corresponding side.
