Analysis of ROC for Edge Detectors
Kai Yi Ji
This paper presents an evaluation of edge detectors using receiver operating
characteristic (ROC) analysis on the BIPED dataset. Our study examines the
benefits and drawbacks of applying this technique in Matlab. We observed that
while ROC analysis is suitable for certain edge filters, but for filters such
as Laplacian, Laplacian of Gaussian, and Canny, it presents challenges when
accurately measuring their performance using ROC metrics. To address this
issue, we introduce customization techniques to enhance the performance of
these filters, enabling more accurate evaluation. Through our customization
efforts, we achieved improved results, ultimately facilitating a comprehensive
assessment of the edge detectors.
