Benchmarking Access Structures for High-Dimensional Multimedia Data
1999
Nascimento, Mario, Colossi, Nathan
Technical report TR99-05. In multimedia databases it is usual to map objects into feature vectors in high-dimensional spaces. In order to speed query processing access structures, or indices, are required. Unfortunately, in the case of similarity queries, which are in fact nearest neighbor ...

Valenzano, Richard, Müller, Martin, Xie, Fan
Most of the satisficing planners which are based on heuristic search iteratively improve their solution quality through an anytime approach. Typically, the lowest-cost solution found so far is used to constrain the search. This avoids areas of the state space which cannot directly lead to lower...

Technical report TR04-23. Precalculating irradiance for photon maps is an enhancement to the photon mapping method that was proposed by Christensen to reduce redundant irradiance calculations during rendering. In this enhancement, irradiance values are precalculated at the location of photons in...

Stroulia, Eleni, Xing, Zhenchang
Technical report TR07-13. Software system grows in size and complexity as it evolves over time. The fact that object-oriented software is increasingly developed using an evolutionary development process makes the situa-tion even worse. The developers face increasing difficulties in comprehending...

Technical report TR02-08. Previous image-based rendering approaches rely on either accurate three-dimensional geo-metric information or dense image samples. It is, therefore, hard to render a complex real scene due to the difficulties of the following two problems: (1) how to model and represent...

Cell Histograms Versus Color Histograms for Image Representation and Retrieval
2001
Nascimento, Mario, Falcao, Alexandre, Stehling, Renato
Technical report TR01-01. Color is a commonly used feature for realizing content-based image retrieval (CBIR). In this context, this paper presents a new approach for CBIR which is based on well known and widely used color histograms. Previous approaches have used a single global color...

Amaral, Nelson, Niewiadomski, Robert
Technical report TR06-06. Research on the performance of implicit k-heaps has shown that aligning data with cache lines and increasing heap arity are effective techniques for improving the data reference locality of heap operations. The technique of tree blocking has long been used to enhance the...
