As a pre-processing tool, superpixel algorithms have been popular used in many computer-vision applications. High efficiency is a desired property of superpixel algorithms, especially in real-time vision systems. In this paper, a novel high-efficient superpixel algorithm is developed based on the watershed algorithm, namely the spatial-constrained ...

We present a new approach for object boundary extraction, called the watersnake. It is a two-step snake algorithm whose energy functional is minimized by the dynamic programming method. It is more robust to local minima because it finds the solution by searching the entire energy space.

We investigate the effectiveness of the divide set produced by watershed algorithms. We introduce the mosaic to retrieve the altitude of points along the divide set. A desirable property is that, when two minima are separated by a crest in the original image, they are still separated by a crest of the same altitude in the mosaic. Our main result states

Significant developments have occurred in India in the past three to four decades with respect to the state of natural resources and human population, as part of various watershed programs. Much experience has been gained by governmental and non-governmental institutions and by the stakeholders engaged in these endeavors.

WHEN I WAS first asked to write this commentary for Frontiers of Health Services Management, knowing that I would be contributing with the likes of Emily Friedman, I must admit I was a bit intimidated. But after reflection, I realized that I was able to offer comments on a subject I know all too well-the uninsured and the lack of a comprehensive ...
