(author), TNO Defensie en Veiligheid (author)The increasing availability and deployment of imaging sensors operating in multiple spectral bands has led to a large research effort in image fusion, resulting in a plethora of pixel-level image fusion algorithms. However, the cognitive aspects of multisensor image fusion have not received much attention in the development of these methods. In...article 2010

Salem, S. (author), Jacobs, E. (author), Moore, R. (author), Hogervorst, M.A. (author), Bijl, P. (author), TNO Defensie en Veiligheid (author)Perception tests establish the effects of spatially band-limited noise and blur on human observer performance. Previously, Bijl showed that the contrast threshold of a target image with spatially band-limited noise is a function of noise spatial frequency. He used the method of adjustment to find the contrast thresholds for each noise frequency...conference paper 2008

(author), TNO Voeding Centraal Instituut voor Voedingsonderzoek TNO (author)The effects of nonoral sensations, such as visual texture and odor, on the size of the first bite were investigated in a series of studies using specially constructed food delivery cups with lower, from which custards were ingested ("ingested custard"), and upper, from which a custard was viewed and/or smelled ("upper custard") compartments....article 2004

TNO Technische Menskunde (author), Toet, A. (author), Hogervorst, M.A. (author), Bijl, P. (author)We argue that visual conspicuity and identifiability are two efficient task-related measures that can be deployed to calibrate synthetic imagery that is intended to be used for human visual search and detection tasks. The conspicuity of a target is operationally defined as the region around the center of the visual field where the target is...conference paper 2004

Bijl, P. (author), Valeton, J.M. (author), TNO Technische Menskunde (author)The characterization of electro-eptical system performance by means of the minimum resolvable temperature difference (MRTD) or minimum resolvable contrast (MRC) has at least three serious disadvantages: (1) the bar pattern stimulus is theoretically and practically unsuitable for 1-D or 2-D spatially sampled systems such as pixel-array cameras, ...article 1998
