This work presents the development of an augmented reality magnification system implemented in a head-mounted display for surgical applications. The system provides a magnified view with a novel control based on tracked sight orientation. The system was evaluated by measuring the completion time of a suturing task performed by surgeons. The magnifying(More)
A method to simulate and model metamorphopsia by means of a deformable Amsler grid is proposed. The interactively deformable grid is based on cubic B-splines to obtain a locally controlled deformation. By simulating metamorphopsia on normal sight volunteers, acquisition of a correction percentage is possible as a result of analyzing the magnitude of the(More)
Quantification of impact craters on planetary surfaces is relevant to understand the geological history of the planet. In order to automatize quantification of lunar craters in digital images, the first step is to develop a computational tool capable of classifying a subwindow of pixels into two possible outputs: crater / non-crater. In this paper, we(More)

This work presents the development of an augmented reality magnification system, termed virtual loupe, implemented in a head-mounted display for surgical applications. The system provides a magnified view with a novel control based on tracked sight orientation. The system was evaluated by measuring the completion time of a suturing task performed by(More)
The activity of beta-N-acetylglucosaminidase (NAG), beta-galactosidase, alpha-L-fucosidase, beta-glucuronidase, beta-glucosidase and alpha-mannosidase was determined in the urine of rats at progressive ages from newborn to old animals. The age-dependence of urinary creatinine, protein and pH values was also studied. Enzyme activity, related to urinary(More)
