Technical report TR04-13. Existing random models for the constraint satisfaction problem (CSP) all require an extremely low constraint tightness in order to have non-trivial threshold behaviors and guaranteed hard instances at the threshold. We study the possibility of designing random CSP models...

Content-Based Image Retrieval Using Binary Signatures
2000
Nascimento, Mario, Chitkara, Vishal, Mastaller, Curt
Technical report TR00-18. Significant research has focused on determining efficient methodologies for retrieving images in large image databases. In this paper, we propose two variations of a new image abstraction technique based on signature bit-strings and an appropriate similarity metric. The...

Technical report TR04-16. This thesis deals with the problem of finding images that contain a given query sub-image, the so-called Content-Based sub-Image Retrieval (CBsIR) problem. We propose a scheme named the Hierarchical Tree Matching (HTM), which relies on a hierarchical tree that encodes...

Renz, Matthias, Kriegel, Hans-Peter, Nascimento, Mario A., Follmann, Anna, Kroeger, Peer, Zuefle, Andreas
Technical report TR10-09. Count queries in wireless sensor networks report the number of sensor nodes for which the measured values satisfy a given query predicate. However, measurements in wireless sensor networks are typically imprecise due to limited accuracy of the sensor hardware or...

Curiosity is a crucial, but not yet well-understood component of intelligence and a better understanding of existing models may lead to a better understanding of curiosity as a whole. In this work, we present a physical robot implementation of the basic curiosity loop introduced by Gordon and...

Technical report TR02-03. Clustering is the problem of grouping data based on similarity and consists of maximizing the intra-group similarity while minimizing the iter-group similarity. While this problem has attracted the attention of many researchers for many years, we are witnessing a...

Oliveira, Stanley, Zaiane, Osmar
Technical report TR04-17. Preserving privacy of individuals when data are shared for clustering is a complex problem. The challenge is how to protect the underlying attribute values subjected to clustering without jeopardizing the similarity between data objects under analysis. To address this...

Technical report TR96-26. Software design methods share many characteristics with design methods in other fields. All these methods are the progeny of philosophies of design that are in turn influenced by more general philosophic movements. This essay begins with the influence of philosophies of...
