watershed I have an image with contours but this ALgorithme don't output a good result, if someone has a good solution please , i need your help

I have an image with contours i like to detect regions. Watershed don't give me a good result.

yes, i have an image and this is url: http://www.filesin.com/6B56C226608/download.html i like to detect regions with closed contour. Please i need your help.

I don't download zip files (or any other files for that matter).

The contours appear to me to be mostly arbitrary on that image. There is, for example, no obvious reason at all why the bottom of the "T" contour should be straight rather than a conic section. Some of the contours appear to be distinctly *not* consistent depth.

There might perhaps be underlying muscular or bone reasons why the contours should go where they are, but I would be surprised if you can deduce their positions from the image.

Answer 1

[Matt Kindig]

Two things:

-Have you looked through the demos for the Image Processing Toolbox at some of the other tools for contour detection? Perhaps the 'edge' and 'bwperim' functions can be of use?

-Can you post the image for us, so that we can offer recommendations?

Answer 2

watershed hates noise, so you might want to smooth the image first if that's the problem

Any one help me what's the best Algorithme to detect contour

Please answer about my Comment about the "contours" appearing to be arbitrary.
