Hi! Although I’m often browsing the forum, it is my first post in here.
I have a problem which might be a simple one, but I’m stuck at it.
I’m trying to segment an image in order to separate the particles and calculate the perimeter of each one of them. I’m using the Trainable Weka Segmentation to segment the image and the results are fine. My problem is after the segmentation. The borders of the particles are sometimes missing a part. There is an example of how it looks like (inside the red circles) [ https://www.dropbox.com/s/gvltfpfroeio9ce/exemplo.jpg?dl=0 ]. It happens because sometimes the border of the particle is almost exactly like it’s interior. Unfortunately I can’t get better images.
I’m trying to find a way to complete the borders automatically (just connect the ends of the lines by a straight line would be good). I tried to solve this problem by changing the segmentation parameters, but the results aren´t good (because of the quality of the image).
What do you all suggest?
