Color correction of underwater images has been considered a difficult task for a number of reasons. Those include severe absorption of the water column, the unpredictable behavior of light under the water surface, limited access to reliable data for correction purposes, and the fact that we are only able to process three spectral channels, which is(More)
People from temperate climates often underestimate the danger of contracting bilharziasis in tropical areas. Since 1960, Swedish soldiers have served on UN duty in the Democratic Republic of the Congo and all have been frequently warned of the danger of contact with fresh water. These warnings have sometimes been ignored on the grounds that the likelihood(More)
The serological response to immunization with a formalin inactivated Rift Valley fever (RVF) vaccine was studied in 963 Swedish UN soldiers serving in the Sinai peninsula. Antibody titres were determined with a plaque reduction neutralization test (PRNT). Attempts were made to give all soldiers three injections (1 ml s.c. days 0, 7-10 and 28-30) but 128(More)
A comparison of the accuracy and robustness of different data driven methods for intensity nonuniformity field estimation (background shading estimation) on simulated and real images of fluorescence stained cells is presented. A novel attempt to reduce the parameter space of a Bspline based algorithm for shading estimation using automatic thresholding with(More)
Swedish United Nations Emergency Forces soldiers serving in Egypt and the Sinai peninsula were serologically tested for hemagglutination-inhibiting antibodies to Rift Valley fever (RVF) virus. Eight of 170 were positive. RVF has not been reported outside Africa, and a survey of 500 Swedish soldiers who had not served in the Middle East or Africa revealed no(More)
