چکیده
ISSN 2277 5080 | © 2012 Bonfring Abstract--Shoe prints at the place of crime provide valuable forensic evidence. In this paper, a novel approach of Shoeprint identification has been proposed and discussed. Fisher linear discrimination (FLD) is used to extract the features in shoe print images. For dimensionality reduction, PCA has been used. In addition to that, a pass band DCT has been used for dimensionality reduction prior to the extraction of feature vectors. This makes the shoe print recognition process more robust against degradations like noises, orientations and blurred images which are common in shoe print images. It can significantly improve the recognition rates and effectively reduce the dimension of feature space.

Full Shoe Print Recognition based on Pass Band DCT and Partial Shoe Print Identification using Overlapped Block Method for Degraded Images
In this paper, a novel approach is made to discard the degradations in full shoe prints and partial shoe prints, in processing those images for recognition. A pass band DCT coefficient has been used to extract feature vectors. A more robust approach has been dealt with to find the matching between the partial shoe prints and the images in the data base. This method makes the shoe print recognit...

We introduce in this paper two Enhanced Fisher Linear Discriminant (FLD) Models (EFM) in order to improve the generalization ability of the standard FLD based classifiers such as Fisherfaces. Similar to Fisherfaces, both EFM models apply first Principal Component Analysis (PCA) for dimensionality reduction before proceeding with FLD type of analysis. EFM-1 implements the dimensionality reductio...
