Deep frequency-recurrent priors for inverse imaging reconstruction

•A multi-profile high-frequency transform-guided denoising autoencoder for attainting deep frequency recurrent prior.•We extract a set of multi-profile high-frequency components via a specific transformation.•The learned high-frequency prior information is incorporated into classical iterative recon...
