Member Data Documentation

FP

int eVision::EasyDeepLearning::EROCPoint::FP

The False Positive count: it is the number of good image classified as defective.

FPR

float eVision::EasyDeepLearning::EROCPoint::FPR

The False Positive Rate: it is the number of good image classified as defective, normalized by the number of good images.

N

int eVision::EasyDeepLearning::EROCPoint::N

The Negative count: it is the number of good images.

P

int eVision::EasyDeepLearning::EROCPoint::P

The Positive count: it is the number of defective images.

Threshold

float eVision::EasyDeepLearning::EROCPoint::Threshold

The threshold associated with the true and false positive rates (see EUnsupervisedSegmenter::SetClassificationThreshold).

TP

int eVision::EasyDeepLearning::EROCPoint::TP

The True Positive count: it is the number of defective images classified as defective.

TPR

float eVision::EasyDeepLearning::EROCPoint::TPR

The True Positive Rate: it is the number of defective images classified as defective, normalized by the number of defective images.

The TPR can be NaN (Not A Number) if the metrics were computed using only good images.
