Untrained network
WebMay 18, 2024 · Nonblind image deconvolution (NID) is about restoring the latent image with sharp details from a noisy blurred one using a known blur kernel. This paper presents a dataset-free deep learning approach for NID using untrained deep neural networks (DNNs), which does not require any external training data with ground-truth images. Based on a … WebJun 21, 2024 · Alternatively, deep learning-based reconstruction methods offer the promise of better priors, but require many thousands of ground truth training pairs, which can be difficult or impossible to acquire. In this work, we propose an unsupervised approach based on untrained networks for compressive image recovery.
