Abstract
Systems and methods for reducing noise in sensors are described. In some embodiments, measurement values for selected pixels may be processed to remove signals that are common to groups of pixels. In some embodiments, offset values between pixel groups may be determined. In some embodiments, the determined offset values may be used to remove or suppress artificial discontinuities.
