Proposed a Recurrent Gradient Descent Network (RGDN) by systematically incorporating deep neural networks into a fully parameterized gradient descent scheme for image deconvolution.
The main objective of this work is to develop a Recurrent Gradient Descent Network (RGDN) which serves as an optimizer to de-convolute the images. Image deconvolution, also known as image deblurring, aims to recover a sharp image from an observed blurry image. Single image deconvolution is challenging and mathematically ill-posed due to the unknown noise and the loss of the high-frequency information.
Many conventional methods resort to different natural image priors based on manually designed empirical statistics, which usually shows inferior results and time-consuming in optimization. We propose a Recurrent Gradient Descent Network (RGDN) by systematically incorporating deep neural networks into a fully parameterized gradient descent scheme.
