From: Reference point detection for camera-based fingerprint image based on wavelet transformation
Le & Van [5] evaluated their method with reference points that detected by human experts (denoted with black square).(a)–(d) example of their accepted cases where the detected core-point has distance error is less than 20 pixels, and (e)–(h) shows their false cases, which is the detected core-point has distance error greater than 20 pixels.
