  • Mosaics

  • Redundant MeasurementsGeneralized Mosaicing: Yoav Schechner and Shree Nayar

  • Scanning with Less RedundancyDifferent rows = Different optical characteristics

  • Generalized MosaicingcameraSpatially varying filterSchechner, Nayar, Generalized mosaics

  • Mosaic + High Dynamic Range

  • Fusion of MeasurementsMaximum-Likelihood SolutionSchechner, Nayar, Generalized mosaics

  • Generalized Mosaicing: Yoav Schechner and Shree NayarLog of the mask

  • Mask Self-CalibrationUnknown filter (vignetting)Schechner, Nayar, Generalized mosaics

  • Image RegistrationSchechner, Nayar, Generalized mosaics

  • Bias towards no motionSchechner, Nayar, Generalized mosaicsImage Registration

  • Schechner, Nayar, Generalized mosaicsImage Registration
