One Fish, Two Fish, Butterfish, Trumpeter: Recognizing Fish in Underwater Video
This paper presents a deformable template object recognition method for classifying fish species in underwater video. This method can be a component of a system that automatically identifies fish by species, improving upon previous works which only detect and track fish and those that rely on significant inter-species shape variations or special equipment. Our method works with video shot by a ...
متن کاملOne and Two-individual Movements of Fish after Chemical Exposure
Movement behavior of an indicator species, zebrafish (Danio rerio), was analyzed with one-and two-12 individual groups before and after treatment with a toxic chemical, formaldehyde, at a low 13 concentration (1 ppm). After the boundary area had been determined based on experimental data, 14 intermittency was defined as the probability distributions of the shadowing time during which data 15 we...
متن کاملOne Fish, Two Fish, Red Fish, Blue Fish: Geography, Ecology, Sympatry, and Male Coloration in the Lake Malawi Cichlid Genus Labeotropheus (Perciformes: Cichlidae)
While sexual selection on male coloration has been important in haplochromine cichlid speciation, few studies to date have examined potential environmental influences on color pattern evolution. Data from multiple sources on male nuptial coloration of the Lake Malawi endemic genus Labeotropheus were used to examine the relationship between color patterns and the environments in which these patt...
متن کاملOne fish, two fish, red fish, blue fish: effects of price frames, brand names, and choice set size on Medicare Part D insurance plan decisions.
Because many seniors choose Medicare Part D plans offering poorer coverage at greater cost, the authors examined the effect of price frames, brand names, and choice set size on participants' ability to choose the lowest cost plan. A 2×2×2 within-subjects design was used with 126 participants aged 18 to 91 years old. Mouselab, a web-based program, allowed participants to choose drug plans across...
متن کاملSynchronised Swimming of Two Fish
We study the fluid dynamics of two fish-like bodies with synchronised swimming patterns. Our studies are based on two-dimensional simulations of viscous incompressible flows. We distinguish between motion patterns that are externally imposed on the swimmers and self-propelled swimmers that learn manoeuvres to achieve certain goals. Simulations of two rigid bodies executing pre-specified motion ...
