Abstract(in English) | ISTA (Iterative Shrinkage-Thresholding Algorithm) is one of the basic algorithms used in compressed sensing to estimate sparse signals from observed signals. Recently, techniques such as Trainable ISTA that combine deep learning with compressed sensing algorithms have achieved high signal recovery performance. In this paper, we propose the DAE-ISTA that uses a DAE (Denoising AutoEncoder) with pre-trained image features as the shrinkage function of ISTA for image recovery. Numerical simulations based on real data have revealed that DAE-ISTA improves the image recovery performance compared with an existing method. |
