i am doing a project to calculate bone age using x-ray image of hand. i almost completed the project, but the 1st step that is the segmentation is not working properly. so i done the segmentation using a third party software Fiji-x . In segmentation i want to Separate the bones from x-ray image by removing the skin particles in the x-ray. can anybody suggest a solution for this problem? my project Success is fully depends on this segmentation step.
