减薄等高线的二进制图像 [英] Thinning contour lines in a binary image

问题描述

我有等高线的二进制图像，需要净化所有不必要的像素的每个轮廓线，留下最小连接线后面。

I have a binary image with contour lines and need to purify each contour line of all unnecessary pixels, leaving behind a minimally connected line.

有人可以给我一个来源，code例如或进一步信息，此类问题以及在何处寻找帮助，好吗？

Can somebody give me a source, code example or further information for this kind of problem and where to search for help, please?

推荐答案

如果你正在寻找Python实现，看看一个的 scikits图像。

If you're looking for python implementations, have a look a scikits-image.

他们的一个例子实质上是您的使用情况。

One of their examples is essentially your use case.

另外，如果你想坚持直SciPy的，您可以使用连续的使用 scipy.ndimage 糜烂和扩张术。 （由于@AxezDNyde提到。）

Alternately, if you wanted to stick to "straight" scipy, you can do this by using successive erosions and dilations using scipy.ndimage. (As @AxezDNyde mentions.)
