Fast Fencing
We consider very natural “fence enclosure” problems studied by Capoyleas, Rote, and Woeginger and Arkin, Khuller, and Mitchell in the early 90s. Given a set S of n points in the plane, we aim at finding a set of closed curves such that (1) each point is enclosed by a curve and (2) the total length of the curves is minimized. We consider two main variants. In the first variant, we pay a unit cos...
متن کاملEffects of Road Fencing on Population Persistence
Roads affect animal populations in three adverse ways. They act as barriers to movement, enhance mortality due to collisions with vehicles, and reduce the amount and quality of habitat. Putting fences along roads removes the problem of road mortality but increases the barrier effect. We studied this trade-off through a stochastic, spatially explicit, individual-based model of population dynamic...
متن کاملImage De-fencing Revisited
We introduce a novel image defencing method suitable for consumer photography, where plausible results must be achieved under common camera settings. First, detection of lattices with see-through texels is performed in an iterative process using online learning and classification from intermediate results to aid subsequent detection. Then, segmentation of the foreground is performed using accum...
متن کاملAutomatic Image De-fencing System
Tourists and Wild-life photographers are often hindered in capturing their cherished images/videos by a fence that limits accessibility to the scene of interest. The situation has been exacerbated by growing concerns of security at public places and a need exists to provide a tool that can be used for post-processing such “fenced videos to produce a “de-fenced” image. There are several challeng...
متن کاملEffect of uncertainty on the reaction response in fencing.
PURPOSE The objective was to determine the way in which the level of uncertainty produced during the execution of a lunge attack with target change (two or four possible responses) affects reaction-response time parameters and kinematic factors involved in the technical coordination of the attack. METHOD Seventeen fencers from the Spanish National Men's Fencing Team participated in the study,...
