High Amplification Scales Handling Frequency Content and Novel Gradient Sharpening Procedures

High Amplification Scales Handling Frequency Content and Novel Gradient Sharpening Procedures

In this paper, a method for adaptive pure interpolation (PI) in the frequency domain, with gradient auto-regularization, is proposed. The input image is transformed into the frequency domain and convolved with the Fourier transform (FT) of a 2D sampling array (interpolation kernel) of initial size L...
