Forensic Face Sketch Recognition

  Divya T M

A forensic sketch is matched with a database of images. A professional forensic sketch artist draws a sketch of a suspect’s face by listening to a description given by witness. A database has a collection of sketches and images. A much efficient recognition system is implemented in this paper in order to recognize a forensic sketch. firstly, the feature vectors of the face are extracted from both the sketches and images using SIFT & MLBP descriptors. Later the nearest neighbor matching is implemented to match the feature vectors of sketches and images. secondly, the same feature vectors obtained from SIFT & MLBP are further revised to reduce the dimension of SIFT & MLBP feature vectors. A linear Discriminant Analysis is implemented. In this approach, A multiple projection of slices of feature vectors are made. The images in the database are first converted into pseudo-sketches, then the matching of pseudo-sketches with the forensic sketch is done by minimum distance recognition. The two standard databases are CUHK & IIIT-D of sketches and images are used. The recognition rates for both the approaches are compared.

Keywords- Forensic sketch, Recognition, CUHK database, IIIT-D database, SIFT, MLBP, LFDA.
