Scale Space of Gradient Watershed
梯度水线的尺度空间

In this paper, we propose a stratification transformation on the intensity surface of grayscale image. This transformation is confined by the original watershed partition, and after this transformation, there exists a strict causality between gradient watershed under different scales of geodesic reconstruction. In this way, the scale space of gradient watershed can be established. Some possible applications of watershed transformation on image sequence analysis are discussed, and by the utilization of the multiscale framework of gradient watershed, the efficiency and stability can be greatly improved.
