Jerry Sedgewick is an independent scientific consultant specializing in image quantitation; digital imaging, ethics and image acquisition training; and in the production of automated and semi-automated add-on Photoshop software featuring means for retaining corrective steps. He served for 15 years as the director of a core microscopy, molecular biology and genomics facility (the Biomedical Image Processing Laboratory) at the University of Minnesota.
His research interests are in the development of streamlined ways to separate features of interest from surrounding areas (segmentation) within images for effective image analysis; and in means through which to retain essential image information when taking corrective actions in post-processing. For the latter, his research interests also include the discovery of objective means for correcting the kinds of images that are meant to be seen on a perceptual (subjective) level.
Jerry Sedgewick has published two books on digital imaging, with emphasis on Photoshop, along with several book chapters. He has co-authored papers for Science, PNAS, and Circulation, along with several other papers in various journals on research areas that include cancer, immunology, AIDs, and medical devices. On his own, he built 2 multiphoton confocal instruments: one a custom-built instrument for video-rate imaging of in vivo specimens using a resonant mirror assembly; the other, a modification of an Olympus FV300 specifically for Second Harmonic Generation. He has also built illumination sources for IR irradiation, and for the elimination of bleaching when using fluorescently labeled specimens.
