摘要：

An alternative procedure is developed to the smoothed linear fitting method of McDonald and Owen. The procedure is based on the detection of discontinuities by comparing, at any given position. three smooth fits. Diagnostics are used to detect discontinuities in the regression function itself (edge detection) or in its first derivative (peak detection). An application in electron microscopy is discussed.
