| Abstract | The long-researched challenge of latent print age estimation has recently been re-visited using non-invasive capturing devices and time series. While this approach was able to provide an objective performance measure for the first time, the robustness of the scheme towards different contextual conditions is barely known. Also, StirTrace has recently been adapted from the well-known StirMark framework to the benchmarking of latent fingerprints. In this paper, the image manipulation techniques of StirTrace are transferred to the age estimation challenge and estimation performance is benchmarked for 500 short-term aging time series under varying contextual conditions. Results show that time series preprocessing is sensitive to pixel-depth reduction as well as different types of noise. Furthermore, a decreased image size has a stronger impact on the age estimation performance than a decreased resolution. The addition of texture for substrate simulation and median cut filtering for smudged print simulation are found to not be optimal in the aging context for representing this kind of distortions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
