More Information
Summary:The invention provides a fast and high quality image/video interpolation method and apparatus. An up-sampling step first estimates the diagonal missing pixels and interpolates the remaining missing pixels based on the estimation result. An edge-sensing interpolator is provided to guide the interpolation automatically along the edges, where local gradients are non-linearly mapped to achieve the weights. A post-processing refinement step then updates the interpolated high resolution image iteratively, by adding the error between the observed low resolution image and the simulated low resolution image, to attain a clear, natural and visually pleasuring high resolution output.
