37. AVALIAÇÃO DE ALGORITMOS DE MOVIMENTO PARA A COMPRESSÃO DE SEQÜÊNCIAS DE IMAGENS / EVALUATING MOTION ESTIMATION ALGORITHMS FOR VIDEO COMPRESSION
Este trabalho teve por objetivo estudar algoritmos de estimação de movimento baseados na técnica de casamento de bloco a fim de avaliar a importância da sua escolha na construção de um codificador para uso em compressão de seqüência de imagens. Para isto foram estudados quatro algoritmos baseados na técnica de casamento de bloco, sendo verificada a

38. Image processing: some challenging problems.
Image processing can be broadly defined as the manipulation of signals which are inherently multidimensional. The most common such signals are photographs and video sequences. The goals of processing or manipulation can be (i) compression for storage or transmission; (ii) enhancement or restoration; (iii) analysis, recognition, and understanding; or (iv) vis

39. Combinations of fluorescently labeled pulmonary surfactant proteins SP-B and SP-C in phospholipid films.
Hydrophobic pulmonary surfactant (PS) proteins B (SP-B) and C (SP-C) modulate the surface properties of PS lipids. Epifluorescence microscopy was performed on solvent-spread monolayers of fluorescently labeled porcine SP-B (R-SP-B, labeled with Texas Red) and SP-C (F-SP-C, labeled with fluorescein) in dipalmitoylphosphatidylcholine (DPPC) (at protein concent

40. Contribution of the Cytoskeleton to the Compressive Properties and Recovery Behavior of Single Cells
The cytoskeleton is known to play an important role in the biomechanical nature and structure of cells, but its particular function in compressive characteristics has not yet been fully examined. This study focused on the contribution of the main three cytoskeletal elements to the bulk compressive stiffness (as measured by the compressive modulus), volumetri
