An Evaluation of Oracle\u27s StillImage Plugin as a Platform for Dynamic Image Search

In this project, we look at some different off­-the­-shelf solutions for creating an image search engine that, given an unknown cover for a comic book, would return relevant information about a matching comic book in the database. The project first examines some alternative tools available to developers to do image search and comparison, and then looks at Oracle\u27s solution for image comparison, Still Image. A prototype search is built to test Oracle\u27s capabilities and is evaluated on speed and quality of results. In the end, Oracle is determined to be a useful tool for storing and comparing images, but is still not capable of searching for an image in a reasonable amount of time

Metadata Guidelines for Digital Resources at Texas A&M University Libraries

These guidelines were written to help TAMU partners create high quality metadata for digital collections deposited in the repository at TAMU Libraries. The goal is to ensure an acceptable level of consistency and completeness of metadata across all collections in the repository in order maximize their potential for discovery for the TAMU community. These guidelines were also written to help Digital Initiatives personnel at TAMU Libraries to map metadata to appropriate fields in Dublin Core and MODS, the two most commonly used schema within the TAMU repository. The guidelines, as they are currently written, address metadata elements that may be recorded for ALL digital collections within the repository, regardless of whether they consist of text, still images, video, or any other type of content. It is likely that specific formats may require additional metadata than what is currently described in this document. More specific guidelines for various formats may be added to this document in the future. It should be noted that this document is a work in progress and will continue to be revised and expanded upon

Hierarchical structuring of Cultural Heritage objects within large aggregations

Huge amounts of cultural content have been digitised and are available through digital libraries and aggregators like Europeana.eu. However, it is not easy for a user to have an overall picture of what is available nor to find related objects. We propose a method for hier- archically structuring cultural objects at different similarity levels. We describe a fast, scalable clustering algorithm with an automated field selection method for finding semantic clusters. We report a qualitative evaluation on the cluster categories based on records from the UK and a quantitative one on the results from the complete Europeana dataset.Comment: The paper has been published in the proceedings of the TPDL conference, see http://tpdl2013.info.

Utah State University - University Libraries Metadata Application Profile for CONTENTdm Digital Collections

The Utah State University Libraries Digital Collections Application Profile outlines the metadata fields, mappings, definitions, and resources used to assign metadata for digital collections in the USU CONTENTdm repository. Utah State University is a collection partner of the Mountain West Digital Library (MWDL). Therefore, this profile pulls substantially from the MWDL application profile 2.0, which is available at this URL: http://mwdl.org/docs/MWDL_DC_Profile_Version_2.0.pd

The three-dimensional structure of Galactic molecular cloud complexes out to 2.5 kpc

Knowledge of the three-dimensional structure of Galactic molecular clouds is important for understanding how clouds are affected by processes such as turbulence and magnetic fields and how this structure effects star formation within them. Great progress has been made in this field with the arrival of the Gaia mission, which provides accurate distances to $\sim10^{9}$ stars. Combining these distances with extinctions inferred from optical-IR, we recover the three-dimensional structure of 16 Galactic molecular cloud complexes at $\sim1$pc resolution using our novel three-dimensional dust mapping algorithm \texttt{Dustribution}. Using \texttt{astrodendro} we derive a catalogue of physical parameters for each complex. We recover structures with aspect ratios between 1 and 11, i.e.\ everything from near-spherical to very elongated shapes. We find a large variation in cloud environments that is not apparent when studying them in two-dimensions. For example, the nearby California and Orion A clouds look similar on-sky, but we find California to be more sheet-like, and massive, which could explain their different star-formation rates. In Carina, our most distant complex, we observe evidence for dust sputtering, which explains its measured low dust mass. By calculating the total mass of these individual clouds, we demonstrate that it is necessary to define cloud boundaries in three-dimensions in order to obtain an accurate mass; simply integrating the extinction overestimates masses. We find that Larson's relationship on mass vs radius holds true whether you assume a spherical shape for the cloud or take their true extents.Comment: accepted for publication by MNRAS, 23 pages, 9 figures, 3 table

Optical network technologies for future digital cinema

Digital technology has transformed the information flow and support infrastructure for numerous application domains, such as cellular communications. Cinematography, traditionally, a film based medium, has embraced digital technology leading to innovative transformations in its work flow. Digital cinema supports transmission of high resolution content enabled by the latest advancements in optical communications and video compression. In this paper we provide a survey of the optical network technologies for supporting this bandwidth intensive traffic class. We also highlight the significance and benefits of the state of the art in optical technologies that support the digital cinema work flow
