2. Tratamento de condições especiais para busca por similaridade em bancos de dados complexos / Treatment of special conditional for similarity searching in complex data bases
A quantidade de dados complexos (imagens, vídeos, séries temporais e outros) tem crescido rapidamente. Dados complexos são adequados para serem recuperados por similaridade, o que significa definir consultas de acordo com um dado critério de similaridade. Além disso, dados complexos usualmente são associados com outras informações, geralmente de tipo

3. Recuperação de vídeos comprimidos por conteúdo / Content-based retrieval of compressed videos
Recent advances in the technology have enabled the increase of the availability of video data, creating large digital video collections. This has spurred great interest in systems that are able to manage those data in a efficient way. Making efficient use of video information requires the development of powerful tools to extract high-level semantics from low

4. Reconhecimento de ações com histogramas de características visuais e contexto adicionado por tranferência de aprendizagem
This thesis addresses the task of recognizing human actions in realistic videos based on their visual content. Such an ability has a wide variety of applications in specic settings, but this work is above all motivated by the idea that efective visual descriptors and models need to be provided in order to make current search engines better able to cope with

5. Bulk-loading Dynamic Metric Acess Methods / Operação de carga-rápida (bulk-loading) em métodos de acesso métricos
The similarity degree between data elements is the primordial factor for information retrieval in databases that handle complex data, such as genetic sequences, time series and multimedia objects (long images, audio, videos, texts). To answer these queries in a reduced time, it is necessary methods that use metrics to evaluate the similarity between elements

6. Análise de conteúdo de vídeo por meio de aprendizado ativo
Advances in compression techniques, decreasing cost of storage, and high-speed transmission have facilitated the way videos are created, stored and distributed. As a consequence, videos are now being used in many applications areas. The increase in the amount of video data deployed and used in today s applications reveals not only the importance as multimedi

7. Um sistema de recomendação para mídias baseado em conteúdo nebuloso.
This work presents the development of a content-based recommender system for media of the AMMO (Authoring and Manipulation of Multimedia Objects) environments multimedia database. This environment keeps inexact semantic information that describes the media. This projects objective was to recommend media using this fuzzy information. Other informations that s

8. Operadores binários para consulta de similaridade em banco de dados multimídia / Binary operators in multimidia data base
The present databases managers are not adequated for complex data manipulation and among them we point out the multimedia data that to speed up the query use the equality operation on the index structure. Equality operations are not much used in operations that involve complex data sence the presence of two elements extremely equal is rare. An operator class

9. Visualizing the organization and behavior of metric access methods: Applications in similarity queries / "Visualizando a organização e o comportamento de estruturas métricas: aplicações em consultas por similaridade"
The use of computers by an increasing variety of applications led the Database Management Systems (DBMS) to be used to store a wide range of complex data types, such as images, sounds, DNA chains, etc. Queries based on the total order relationship and/or equality can not be applied or have a limited range of applications when performed over these datasets. I

10. Storage and management of similar images
Numerical images are becoming more and more important and an increasing emphasis on multimedia applications has resulted in large volumes of images. However, images need a large memory space to be stored, so their efficient storage and retrieval generate challenges to the database community. This paper proposes a new algorithm for an efficient storage of set

11. How hyper are we? A look at hypermedia management in academic health sciences libraries.
Advances in instruction-delivery technology have a direct impact on academic media centers. New technology challenges librarians philosophically, financially, and ethically to provide access to information and instructional systems. Each institution has a unique set of circumstances governing decisions to provide access to hypermedia. If patron needs are met

12. Problem-oriented Prefetching for an Integrated Clinical Imaging Workstation
Prefetching methods have traditionally been used to restore archived images from picture archiving and communication systems to diagnostic imaging workstations prior to anticipated need, facilitating timely comparison of historical studies and patient management. The authors describe a problem-oriented prefetching scheme, detailing 1) a mechanism supporting
