Abstract : Psychophysical experiments in visual search, texture segregation, motion segmentation, lightness perception on 3-D surfaces, and the perception of heading have been designed, executed, and analyzed. Data from these experiments and others has been used to refine parameter selection for the Boundary Contour System model of early human vision and its application to image processing. Mingolla has obtained a security clearance and consulted with Dr. Allen Waxman's group at MIT Lincoln Laboratory on night vision and image processing. Mingolla continues to work in modeling (neural architectures for brightness perception, illusory contours, figure/ground segmentation, search for targets in clutter, motion perception) and image processing (segmentation or enhancement of SAR and LADAR imagery).
