A Luminance- and Contrast-Invariant Edge-Similarity Measure
Sanjeev Kumar, Sim Heng Ong, S. Ranganath, Fook Tim Chew · IEEE Transactions on Pattern Analysis and Machine Intelligence · 2006
A novel similarity measure for edge-detection that is robust to varying luminance and contrast is presented. It incorporates a regularization term and employs directional FIR edge filters with hyperbolic tangent profiles to ensure improved noise performance and edge localization compared to classical methods.
