Abstract
The super-resolution problem is considered using a mean-squared error minimizing solution of a generalized undersampling model in this non-iterative frequency domain approach. While previous frequency domain approaches have been based on a bandlimited image model, this approach uses a non-bandlimited stationary spectral model. This allows improved reconstruction of certain image features. The model and algorithm are presented along with an example
