2. 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. Making medical visual information available on the WEB
This paper presents a new metadata model to describe and retrieve medical visual information, such images and their diagnoses, using the Web. The classes of this model allow describing medical images of different medical areas, including their properties, components and relationships. This model supports the international classification of diseases and relat

6. Vocábularios visuais aplicados à detecção de edifícios em fotografias históricas
In this work, we propose a technique based on a bag-of-keypoints representation to identify images containing buildings in the photographic collection of Arquivo Público Mineiro (APM), the Archives of the State of Minas Gerais. We evaluate the proposed work using digitized versions of the original. Digitization is an effective procedure to make collections

7. Evaluating human-computer interaction techniques for content-based image retrieval systems through a case study / Análise e avaliação de técnicas de interação humano-computador para sistemas de recuperação de imagens por conteúdo baseadas em estudo de caso
The content-based image retrieval (CBIR) is a challenging area of the computer science that has been growing in a very fast pace in the last years. CBIR systems employ techniques for extracting features from the images, composing the features vectores, and store them together with the images in data bases management system, allowing indexing and querying. CB

11. A pratical and eficient approach of searches for similarity to support diagnose by images. / Uma abordagem prática e eficiente de consultas por similaridade para suporte a diagnóstico por imagens.
This works presents the main characteristics of a diagnosis support system based on image similarity search for medical applications. This system was developed to be used in the Clinical Hospital of Ribeirao Preto of the University of Sao Paulo. The content-based image retrieval (CBIR) researching area has evolved greatly in the last years. Thus, a CBIR syst
