This set of MATLAB files implements Level Set Methods and follows Osher and Fedkiw's book. A combination of curvature-based forces, vector field-based forces and forces in the normal direction can be used.
* This toolbox currently implements only a 2-D interface (curve) evolution. Extending to 3-D interface (surface) evolution is trivial because of its modular structure based on 1-D functions (I'll do this soon).
* 1st, 2nd and 3rd order accurate Essentially Non-Oscillatory (ENO) and 5th order accurate Weighted ENO (WENO) are supported throughout the toolbox for derivative calculations.
* A function for re-initialization of a signed distance function is provided (reinit_SD).
* A high-level function (evolve2D) is provided that can utilize any combination of: 1) a force in the normal direction to the curve, 2) a curvature-based force, 3) evolution under the influence of an external vector field.
A tag is like a keyword or category label attached to an entry in the Link Exchange. Tags make it easier to find or recall particular links of interest. They're also a good way to categorize your bookmarked items, so you can browse your bookmarks by subject.
Tags benefit the community, too. Anyone who is logged in can tag a Link Exchange item. This means that tagging provides a way to see the big trends in Link Exchange content.
What makes a good tag?
A good tag helps people find the entry. When you tag a link, think about how you might search for that link in the future. Try tagging with several relevant terms, even if they're unrelated to one another. For example, you might want search for a link using either "video" or "image processing" as the tag search term, so it's a good idea to apply both of those tags. Go ahead and experiment with tag searches — it's the best way to learn what tagging is all about. Try adding and deleting tags, too.
How to Tag
Tag your new submission
Start typing in the Tag box, or click on a tag from the list that displays near the box. If you change your mind, click again to remove the tag from your list. Tags are separated by commas. If you want to apply a tag that uses more than one word, make sure there are no commas in the tag itself. Otherwise, the tag will be divided up into multiple tags. Note that when you search for a multi-word tag, you must enclose it in quotes.
Tag an existing link
You can add a tag to an existing entry on the View Link page. Scroll down to the Tags for this Link heading. Click on Add Tags link and type a new tag.
