- W2357180693 abstract "For a noisy discrete curve,the orientation angles of scaling invariant intrinsic variables reflect its bended degree.So first the orientation angle sequence of original curve is filtered by bilateral filtering method.Then the vertex coordinates of the smoothed curve are reconstructed by the filtered scaling invariant variables.The reconstruction of the smoothed curve is formulated as a sparse linear system,which can be easily solved by some solver library.Furthermore,the different requests in practical applications can be satisfied by adding linear constraints in the linear system.This method can be easily generalized to the planar tree graph and triangular mesh.The proposed approach is simple and fast and can obtain satisfied results by presenting some experimental examples,not only avoiding shrinkage,but also preserving the features of the original curve." @default.
