Feature Preserving Nonlinear Image Interpolation

Volume graphics shaders for GPU

“…Initial approaches use genetic algorithms to extract Fourier coefficients [28]. Interpolation of B-splines is used for gradient estimation to estimate accurate gradients for shading [29] as well as for extraction of features using the adaptive bi-directional flow [30,31]. Artifacts are removed by normal diffusion along the tangent direction and image features are preserved.…”
