Image Classifiers for Scene Analysis
Le Saux B, Amato G
The semantic interpretation of natural scenes, generally so obvious and effortless for humans, still remains a challenge in computer vision. We intend to design classifiers able to annotate images with keywords. Firstly, we propose an image representation appropriate for scene description: images ar... e segmented into regions and indexed according to the presence of given region types. Secondly, we propound a classification scheme de- signed to separate images in the descriptor space. This is achieved by combining feature selection and kernel-method-based classification.

Similarity search - The metric space approach
Zezula P, Amato G, Dohnal V
Similarity searching has become a fundamental computational task in a variety of application areas, including multimedia information retrieval, data mining, pattern recognition, machine learning, computer vision, biomedical databases, data compression and statistical data analysis. In such environme... nts, an exact match has little meaning, and proximity/distance (similarity/dissimilarity) concepts are typically much more fruitful for searching. In this tutorial, we review the state of the art in developing similarity search mechanisms that accept the metric space paradigm. We explain the high extensibility of the metric space approach and demonstrate its capability with examples of distance functions. After a survey of specialized partitioning and pruning concepts, we introduce the main indexing representatives and provide performance comparison. The efforts to further speed up retrieval are demonstrated by a class of approximated techniques and the very recent proposals of scalable and distributed structures based on the P2P communication paradigm.

Similarity Search: the metric space approach
Zezula P, Amato G, Dohnal V, Bako M
In the Information Society, information holds the master key to economic inuence and success. But the usefulness of information depends critically upon its quality and the speed at which it can be transferred. In domains as diverse as multimedia, molecular biology, computer-aided design and marketin... g and purchasing assistance, the number of data resources is growing rapidly, both with regard to database size and the variety of forms in which data comes packaged. To cope with the resulting information overkill, it is vital to nd tools to search these resources efciently and effectively. Hence the intense interest in Computer Science in searching digital data repositories. But traditional retrieval techniques, typically based upon sorting routines and hash tables, are not appropriate for a growing number of newly-emerging data domains. More exible methods must be found instead which take into account the needs of particular users and particular application domains. This book is about nding efcient ways to locate user-relevant information in collections of objects which have been quantied using a pairwise distance measure between object instances. It is written in direct response to recent advances in computing, communication and storage which have led to the current ood of digital libraries, data warehouses and the limitless heterogeneity of Internet resources. The scale of the problem can be gauged by noting that almost everything we see, hear, read, write or measure will soon be available to computerized information systems. In such an environment, varied data modalities such as multimedia objects, scientic observations and measurements, statistical analyses and many others, are massively extending more traditional attribute-like data types.

Approximate similarity search in metric spaces
Amato G
There is an urgent need to improve the efficiency of similarity queries. For this reason, this thesis investigates approximate similarity search in the environment of metric spaces. Four different approximation techniques are proposed, each of which obtain high erformance at the price of tolerable i... mprecision in the results. Measures are defined to quantify the improvement of performance obtained and the quality of approximations. The proposed techniques were tested on various synthetic and real-life files. The results of the experiments confirm the hypothesis that high quality approximate similarity search can be performed at a much lower cost than exact similarity search. The approaches that we propose provide an improvement of efficiency of up to two orders of magnitude, guaranteeing a good quality of the approximation. The most promising of the proposed techniques exploits the measurement of the proximity of ball regions in metric spaces. The proximity of two ball regions is defined as the probability that data objects are contained in their intersection. This probability can be easily obtained in vector spaces but is very difficult to measure in generic metric spaces, where only distance distribution is available and data distribution cannot be used. Alternative techniques, which can be used to estimate such probability. [show more]

Metric inverted file.
Amato G
MI-File (Metric Inverted File) allows you to perform approximate similarity search on huge datasets. As an example give a look at the Image Similarity Search Engine, which allows you searching in a dataset of more than 100 millions images, that was built using the MI-File library. The technique is b... ased on the use of a space transformation where data objects are represented by ordered sequences of reference objects. The sequence of reference objects that represent a data object is ordered according to the distance of the reference objects from the data object being represented. Distance between two data objects is measured by computing the spearmann footrule distance between the two sequence of reference objects that represent them. The closer the two data objects the most similar the two sequence of reference objects. The index is based on the use of inverted files. [show more]

Approximate similarity search

Similarity searching is fundamental in various application areas. Recently it has attracted much attention in the database community because of the growing need to deal with large volume of data. Consequently, efficiency has become a matter of concern in design. Although much has been done to develo... p structures able to perform fast similarity search, results are still not satisfactory, and more research is needed. The performance of similarity search for complex features deteriorates and does not scale well to very large object collections. Given the intrinsically interactive nature of the similarity-based search process, the efficient execution of elementary queries has become even more important, and the notion of approximate search has emerged as an important research issue.

We envisage the proposed approach as a valid tool for a streamlined application to the publicly available data generated by many online personal genomic companies.

The DELOS testbed for choosing a digital preservation strategy
Strodl S, Rauber A, Rauch C, Hofman H, Debole F, Amato G

A set of strategies has been proposed, with a range of tools supporting p... arts of digital preservation actions. Yet, with requirements on which strategy to follow and which tools to employ being different for each setting, depending e.g. on object characteristics or institutional requirements, deciding which solution to implement has turned into a crucial decision. This paper presents the DELOS Digital Preservation Testbed. It provides an approach to make informed and accountable decisions on which solution to implement in order to preserve digital objects for a given purpose. It is based on Utility Analysis to evaluate the performance of various solutions against well-defined objectives, and facilitates repeatable experiments in a standardized laboratory setting.
