Fiber Image Separation Algorithm Based on Simplified Distance Transform
Zhang Leb · 2009
A separation algorithm is proposed for heavily-overlapped nature fibers of various forms in cross-sectional.The 8-4 neighbor peel-off,a good approximation to distance transformation,is discussed for the overlapped fiber separation.A distance warp is applied to distance transform based peel-off method to simplify the computation.The result of fiber separation is comparable to distance transform based processing,but the time complexity is largely reduced.In the peel-off processing,the outmost of overlapped fibers is peeled off repeatedly until the location of overlap is determined;the deformation of fibers form is minimized because they are separated from the overlapped point.The experimental results show that the proposed algorithm is efficient and accurate.
