Evaluating Large Image Support for DSpace
نویسندگان
چکیده
Access to large images in digital libraries is desirable from a preservation perspective and may even be a requirement in some domains, such as cartography. However, providing access to large images often poses a problem as a result of the size of the images as well as the limited screen real-estate for displaying the images. Even when these issues are addressed, there is a lack of evidence about how well large image related tasks can be performed in a digital library. In investigating this, a survey was conducted in order to identify well-performing large image support tools and the best of these tools was integrated into DSpace. A user study was conducted in order to evaluate how well large images could be supported in a digital library and it was found that users were able to successfully and easily perform tasks related to large images.

Analysis and Evaluation of Service Oriented Architectures for Digital Libraries
The Service Oriented Architecture (SOA) that underlies the Web Services paradigm of computing is widely regarded as the future of distributed computing. The applicability of such an architecture for digital library systems is still uncertain, as evidenced by the fact that virtually none of the large open source projects (e.g., Greenstone, EPrints, DSpace) have adopted it for internal component ...
متن کاملVisual Word Selection without Re-Coding and Re-Pooling
The Bag-of-Words (BoW) representation is widely used in computer vision. The size of the codebook impacts the time and space complexity of the applications that use BoW. Thus, given a training set for a particular computer vision task, a key problem is pruning a large codebook to select only a subset of visual words. Evaluating possible selections of words to be included in the pruned codebook ...

This paper presents a practical algorithm for facial age estimation from frontal face image. Facial age estimation generally comprises two key steps including age image representation and age estimation. The anthropometric model used in this study includes computation of eighteen craniofacial ratios and a new accurate skin wrinkles analysis in the first step and a pairwise binary support vector...

Training and evaluating support vector machines (SVMs) when large amounts of training data are available, is computationally expensive: for n data points, exact optimization results in O(n) time and O(n) space complexity if general-purpose solvers are used, while prediction involves storing and accessing a significant subset of the training data, demanding time and space as well. Addressing the...
