Direct Sparse Odometry with Rolling Shutter

Neglecting the effects of rolling-shutter cameras for visual odometry (VO) severely degrades accuracy and robustness. In this paper, we propose a novel direct monocular VO method that incorporates a rolling-shutter model. Our approach extends direct sparse odometry which performs direct bundle adjustment of a set of recent keyframe poses and the depths of a sparse set of image points. We estimate the velocity at each keyframe and impose a constant-velocity prior for the optimization. In this way, we obtain a near real-time, accurate direct VO method. Our approach achieves improved results on challenging rolling-shutter sequences over state-of-the-art global-shutter VO

Classificação das intervenções de enfermagem Nursing interventions classification

A enfermagem nos últimos anos está procurando classificar seus diagnósticos, intervenções/ações e seus resultados. O presente trabalho se propõe a apresentar uma das Classificações das Intervenções de Enfermagem propostas por enfermeiras da Universidade de Iowa desde 1987, denominada de Nursing Intervention Classification (NIC) e ainda as razões para sua existência, contribuindo assim com a divulgação de uma das mais avançadas propostas em classificação das intervenções de enfermagem.<br>During the last years, Nursing is selking to classify its diagnoses, interventions/actions and outcomes. Here is presented one of the classifications of nursing interventions that was proposed by nurses of the University of Iowa in 1987, the Nursing Interventions Classifications (NIC) as well as the reasons os its creation, in order to contribute to the dissemination of one of the most advanced proposals for classifying nursing interventions
