2. Vaginal Distention Rodent Model for Fecal Incontinence: A Pilot Study on the Effect on Defecation Behavior
Abstract Objectives Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence

3. Step-by-step optimisation of robotic-assisted radical prostatectomy using augmented reality
ABSTRACT Introduction: Surgical training will be complemented by digitalisation, as the COVID 19 pandemic continues (1). Proximie is an augmented reality (AR) platform that can display up to 4 native camera views, with live or semi live telementoring. It can optimise ergonomics of the surgeon at the console (2), and robotic instrument orientation. We descri

4. Research of the Photoelectric Tracking and Pointing Platform Based on the Servo Control System
ABSTRACT: To improve the speed and accuracy of the photoelectric tracking and pointing platform stable tracking, we took the three-axis photoelectric tracking platform, of which the coupling among the rings is ignored, as the research object. Considering the effects of various disturbances, the stable tracking double closed-loop servo control system was buil

5. Preliminary results on organization on the court, physical and technical performance of Brazilian professional futsal players: comparison between friendly pre-season and official match
Abstract The main aim of this study was to verify possible differences between a friendly pre-season match (FM) and an official in-season match (OM) regarding physical, technical, and organizational performances of a professional Brazilian futsal team. Ten professional futsal athletes participated in this study. The matches were monitored with video cameras

6. Reconhecimento de texto e rastreamento de objetos 2D/3D / Text recognition and 2D/3D object tracking
In this thesis we address three computer vision problems: (1) the detection and recognition of flat text objects in images of real scenes; (2) the tracking of such text objects in a digital video; and (3) the tracking an arbitrary three-dimensional rigid object with known markings in a digital video. For each problem we developed innovative algorithms, which

7. Rastreamento em vídeo das características da pupila / Video tracking of pupil features
The study of the pupil s movements has signicant clinical interest because it acts as an objective indicator of retinal sensitivity to light and, consequently, of the optic nerve. Its permanent oscillation is the result of balance between opposing ows of the sympathetic and parasympathetic nervous system. The pupil s state of an individual allows the diagnos

8. Estimação de velocidade de composições usando processamento de vídeo / Speed estimation.of trains using vídeo processing
This dissertation aims to study a method of estimating the speed of railway vehicles using video processing. The proposed system uses cameras disposed alongside railways to monitor traffic as well as estimate train speeds. Such a system would allow the machinist to have a backup control system, regardless of the control systems already used by the operator o

9. Detecção rápida de legendas em vídeos utilizando o ritmo visual / Fast video caption detection based on visual rhythm
Detecção de textos em imagens é um problema que vem sendo estudado a várias décadas. Existem muitos trabalhos que estendem os métodos existentes para uso em análise de vídeos, entretanto, poucos deles criam ou adaptam abordagens que consideram características inerentes dos vídeos, como as informações temporais. Um problema particular dos vídeos,

10. Video segmentation based on motion coherence of particles in a video sequence
This work describes an approach for object-oriented video segmentation based on motion coherence. Using a tracking process based on adaptively sampled points (namely, particles), 2-D motion patterns are identified with an ensemble clustering approach. Particles are clustered to obtain a pixel-wise segmentation in space and time domains. The segmentation resu

11. Object tracking from compressed video using Kalman Filter and a novel spatiotemporal motion-vector filter.
Video Object Tracking plays a crucial role on several Computer Vision applications, such as Video Surveillance, Intelligent Transportation System (ITS), Human Machine Interface (HMI), Video Indexing and Shopping Behavior Analysis. Nevertheless, the processing power demanded by object tracking techniques still consists in a bottleneck to their wider adoption.

12. Rastreamento de objetos em vídeos e separação em classes / Tracking of objects in videos and separation in classes
A crescente utilização de câmeras de vídeo para o monitoramento de ambientes, auxiliando no controle de entrada, saída e trânsito de indivíduos ou veículos tem aumentado a busca por sistemas visando a automatização do processo de monitoramento por vídeos. Como requisitos para estes sistemas identificam-se o tratamento da entrada e saída de objeto
