I want to recognize handwriting shape and figure out which shape it probably is in the set. Simply saying, if I draw a triangle, the application should recognize it as an triangle. How can I do this using C# or java, any help is appreciated.
Thanks in advance.
These are some of the shapes I need to identify
There is indeed a vast tree of research in shape recognition.
If your shapes are indeed some what predictable and are basic geometry,
the most straightforward way is to find the edges and apply hough transform.
Some managable reading materials for you to start with, [1] Google Scholar for Hough Transform Shape Detection http://scholar.google.com/scholar?q=hough+transform+shape+recognition&hl=en&as_sdt=0&as_vis=1&oi=scholart [2] Hough Transform @ Wiki http://en.wikipedia.org/wiki/Hough_transform
