原标题:Vague Image Recognition in Python

So my goal here is to take an image input and get out a list of the shapes contained in it as an output. Of course, the shapes will not be anything like triangle or square , but just lists of contiguous pixels of like values. My first attempt used a recursive algorithm which roamed the image through paths of like-colored pixels, and added all the ones it could get to to the shape list. This worked for small images, but quickly exceeded the max. recursion depth for larger images.

My current attempt is Iterative, but doesn t want to work. http://pastebin.com/seLbnGE4

Are there any better ways to do it, or are there modules or methods which already exist which would fit my needs?

what you re looking for sounds like "image segmentation" (cf http://en.wikipedia.org/wiki/Segmentation_(image_processing) ). Usually a difficult math problem but implemented in OpenCV.

You may consider using level sets and the "Chan-Vese Algorithim" (cf http://www.univ-pau.fr/~cgout/viscosite/old/20032004/veseChanIJCV2002.pdf ftp://ftp-sop.inria.fr/odyssee/Team/Rachid.Deriche/Lectures/MPRI/IEEEIP2001.pdf )

分散到2个以上地区的综合优化框架是一个具有极大兴趣的公开数学问题。
