Deep Feature Representation for Face Sketch Recognition
Weiguo Wan, Hyo Jong Lee · Advances in Science Technology and Engineering Systems Journal · 2019
Face sketch recognition aims at matching face sketch images to face photo images.The main challenge lies in modality discrepancy between face photo and sketch images.In this work, we propose a new facial sketch-to-photo recognition approach by adopting VGG-Face deep learning network, with which face images can be represented by compact and highly discriminative feature vectors.Different from existing VGG-Face based methods which directly match face sketches to photos, we firstly transform the gallery photos to sketches for decreasing the modality difference.Experimental results on multiple face photo-sketch datasets indicate the superiority of our method.
