Self-recovery reversible image watermarking algorithm. [PDF]
PLoS ONE, 2018 The integrity of image content is essential, although most watermarking algorithms can achieve image authentication but not automatically repair damaged areas or restore the original image.

VARIATIONAL METHODS IN IMAGE RECOVERY
Pesquimat, 2014 We study the semicuadratic minimization problem of the formthis functional arises in image recovery problems, when aimage that describe a real scene, consider like a function f: ΩR2 → R, is observed and reproduced like a function p: Ω R2 → R.

Imaging the Landmarks of Vascular Recovery
Theranostics, 2020 Background: Peripheral arterial disease (PAD) is a major worldwide health concern. Since the late 1990s therapeutic angiogenesis has been investigated as an alternative to traditional PAD treatments. Although positive preclinical results abound in the literature, the outcomes of human clinical trials have been discouraging.

Simulated Annealing Applied to HIO Method for Phase Retrieval
Photonics, 2021 Phase retrieval utilizing Fourier amplitudes plays a significant role in image recovery. Iterative phase retrieval algorithms have been developed to retrieve phase information that cannot be recorded by detectors directly.

A Variational Method in Image Recovery [PDF]
SIAM Journal on Numerical Analysis, 1997 This paper is concerned with a classical denoising and deblurring problem in image recovery, or more precisely, to study the problem of image reconstruction via the calculus of variations and partial differential equations. The model studied for a continuous image is that described by German and German for a numerical image or a slight modification of ...
