Abstract: One of the important cues in solving crimes and apprehending criminals is matching sketches with digital face images. This paper presents an algorithm that extracts discriminating information from local regions of both sketches and digital face images. All details information present in local facial regions are encoded using multi-scale circular Weber’s local descriptor. We propose a novel discriminative descriptor modified WLD i.e. multi-scale circular Weber Local Descriptor.. It is inspired by Weber’s Law, We organize MWLD features to compute a histogram by encoding both differential excitations and orientations at certain locations of an sketch and digital face image. Further, an evolutionary memetic optimization approach is proposed to assign optimal weights to every local facial region for identification purpose. Foreign sketches drawn by sketch artist is of poor quality, a pre-processing technique is used to enhance the quality of images and improve the identification performance. Comprehensive experimental evaluation on different sketch databases show that MCWLD proposed algorithm yields better identification performance compared with the existing face recognition algorithms.
