Contour Stencils: Total Variation along Curves for Adaptive Image Interpolation

  title={Contour Stencils: Total Variation along Curves for Adaptive Image Interpolation},

  journal={SIAM J. Imaging Sciences},
Image interpolation is the problem of increasing the resolution of a given image. An important aspect of interpolation is accurate estimation of edge orientations. This work introduces contour stencils, a new method for estimating the image contours based on total variation along curves. Contour stencils are able to distinguish lines of different orientations, curves, corners, and other geometric features with a computationally efficient formula. Contour stencils are applied in designing an… CONTINUE READING
