Brezinski Inverse and Geometric Product-Based Steffensen's Methods for Image Reverse Filtering

no code implementations2 Jun 2023 Guang Deng

A comprehensive study of 108 variants of the vector Steffensen's methods is presented in the Supplementary Material.

Fast image reverse filters through fixed point and gradient descent acceleration

no code implementations21 Jun 2022 Fernando Galetto, Guang Deng

We study and re-develop state-of-the-art methods from two points of view, fixed point iteration and gradient descent.

Reverse image filtering using total derivative approximation and accelerated gradient descent

1 code implementation8 Dec 2021 Fernando J. Galetto, Guang Deng

We formulate this inverse problem as minimizing a local patch-based cost function and use total derivative to approximate the gradient which is used in gradient descent to solve the problem.

A guided edge-aware smoothing-sharpening filter based on patch interpolation model and generalized Gamma distribution

1 code implementation30 Jul 2021 Guang Deng, Fernando J. Galetto, Mukhalad Al-nasrawi, Waseem Waheed

In the external guidance case, we have developed new algorithms for combining flash and no-flash images and for enhancing multi-spectral images using a panchromatic image.
