Fingerprint Compression Based on Sparse Representation

Fingerprint Compression Based on Sparse Representation Abstract: A new fingerprint compression algorithm based on sparse representation is introduced. Obtaining an overcomplete dictionary from a set of fingerprint patches allows us to represent them as a sparse linear combination of dictionary atoms. In the algorithm, we first construct a dictionary for predefined fingerprint image patches. For […]


Exposing Digital Image Forgeries by Illumination Color Classification

Exposing Digital Image Forgeries by Illumination Color Classification Abstract: For decades, photographs have been used to document space-time events and they have often served as evidence in courts. Although photographers are able to create composites of analog pictures, this process is very time consuming and requires expert knowledge. Today, however, powerful digital image editing software […]
