1. Accuracy and reliability of a videogrammetry system in the analysis of displacement of Wistar rats
Abstract Aims The behavior of laboratory animals has been studied through displacement, with different objectives by researchers. Methods Although different methods have already been used in the tracking of laboratory animals, manual tracking mode videogrammetry for 2D analysis of displacement has not been observed in animal studies. The aim of this study

2. Analise cinematica da movimentação dos membros superiores e inferiores, tronco e cabeça durante a marcha de hemipareticos / Kinematic analysis of upper and lower limbs, trunk and head motions during hemiparetic gait after stroke
The aim of this study was to analyze integrally the movement of upper and lower limbs, trunk and head using the following kinematics variables: joint angles, spatiotemporal variables, trajectory of total body center of mass and partial contributions of the segments for the trajectory of total body center of mass. In order to identify and analyze the gait pat

4. Proposição, validação e aplicação de um novo metodo para analise cinematica tridimensional da movimentação da caixa toracica durante a respiração / Proposition, validation and application of a novel method to the 3D kinematical analysis of the rib cage motion during breathing
The present work aimed to propose and validate a novel method to the 3D kinematical analysis of the rib cage motion during breathing and to show an example of application. The kinematical analysis was used to describe the 3D motion of the ribs during breathing. The 3D coordinates of surface markers positioned on the ribs, sternum and vertebrae were used to c

5. Rastreamento automatico de trajetorias de jogadores de futebol por videogrametria : validação do metodo e analise dos resultados
An objective analysis of the dynamic of a soccer game required the development of efficient methodologies for detection and codification about information during the match. The continuous data about the position in function of time of each players movement, make possible the analysis of covered distances, the displacement region in the field, the distributio

6. Tecnicas de rastreamento e aplicações em analise cinematica de movimentos humanos
The problem of tracking objects from a sequence of video images has been of great interest in the recent years. This interest is motivated, especially, by the wide range of applications such as virtual reality surveillance systems, robotic, human motion analysis, etc. In the human motion analysis, the kinematic variables, (e.g., the covered distance, velocit

7. Methodology for the rib cage motion analysis during breathing / Metodologia para analise da movimentação da caixa toracica durante a respiração
A respiração, em especial a fase da ventilação, é um ato dinâmico dependente da ação coordenada dos músculos respiratórios e da movimentação das estruturas osteo-articulares da caixa torácica. O presente trabalho objetiva propor e avaliar uma metodologia baseada em videogrametria para a análise experimental quantitativa da movimentação da cai
