how labeling a letter in imagemagick ?

[diegomage]

Im trying to labeling a letter but i dont know how


i see this image




how I could do this in imagemagick or other language

please help me

I do not know this well. But see thinning and pruning in the morphology section starting at http://www.imagemagick.org/Usage/morpho ... g_skeleton

very thankyou

[diegomage]

I think that use Convexity Defects and convex hull for detecting lowest point and extreme point could be a solution I dont know if this its possible using imagemagick

[diegomage]

and then using this information for line segmentation

[diegomage]

detect the extreme points I think that if possible but detect Convexity Defects I dont know

[fmw42]

I do not think convex hull helps get the skeleton of the letter. Perhaps you want the convex hull for you other post. Likewise, I think you want to use the skeleton solution from your link in the current post.

You have your answers/questions reversed.d

Skeletonising an image is easy. Dividing a skeleton into line segments, junctions and loops is easy. Finding the direction of a line is fairly easy. For those operations, see http://www.imagemagick.org/Usage/morphology/

The OP contains a graphic with text I can't read. Do you have other questions?

[diegomage]

not really the unique problem in this Could be to detect the convexity defect since you would probably have to detect the skeleton and using connected components detect sub-skeletons for the image would be somewhat complicated

[diegomage]

and then combine point for labeling the image

[diegomage]

For example in the other post for the hands detect red point is not difficult but detect yellow points is more complicated

Would be similar with the letter but that would have to combine that information to do the segmentation
