cv::Mat lib3d::computeBinaryError(const cv::Mat &iComputedBinaryMask, const cv::Mat &iGroundtruthBinaryMask, float &oTruePositiveRate, float &oFalseNegativeRate, float &oFalsePositiveRate, float &oTrueNegativeRate)

Method to compute the pixel wise error between two binary masks.

Parameters:

• iComputedBinaryMask – [in] Computed binary mask.

• iGroundtruthBinaryMask – [in] Ground truth binary mask.

• oTruePositiveRate – [out] Rate of true positive, i.e. pixels in which both iComputedBinaryMask = 1 and iGroundtruthBinaryMask = 1.

• oFalseNegativeRate – [out] Rate of false negatives, i.e. pixels in which iComputedBinaryMask = 0 and iGroundtruthBinaryMask = 1.

• oFalsePositiveRate – [out] Rate of false positives, i.e. pixels in which both iComputedBinaryMask = 1 and iGroundtruthBinaryMask = 0.

• oTrueNegativeRate – [out] Rate of false positives, i.e. pixels in which both iComputedBinaryMask = 0 and iGroundtruthBinaryMask = 0.

Returns:

Colored change mask. Green equals regions of true positives, red of flase positives and blue of false negatives
