A fast hybrid method for apparent ridges

Eric Jardim, Luiz Henrique de Figueiredo
2011 The Visual Computer  
We propose a hybrid method for computing apparent ridges, expressive lines recently introduced by Judd et al.  ...  Unlike their original method, which works over the mesh entirely in object space, our method combines object-space and image-space computations and runs partially on the GPU, producing faster results in  ...  Acknowledgements We thank Waldemar Celes, Diego Nehab, and the referees for their comments and suggestions.  ...
