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.

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. Our approach is based on a variational method. By using the Legendre--Fenchel transform, we show how the nonquadratic criterion to be minimized can be split into a sequence of half-quadratic problems easier to solve numerically.

Image Recovery for Blind Polychromatic Ptychography
SIAM Journal on Imaging Sciences, 2023 Abstract. Ptychography is a lensless imaging technique, which considers reconstruction from a set of far-field diffraction patterns obtained by illuminating small overlapping regions of the specimen. In many cases, the distribution of light inside the illuminated region is unknown and has to be estimated along with the object of ...

SAR image denoising method based on sparse representation
The Journal of Engineering, 2019 The coherent nature of radar illumination causes the speckle effect, which gives the synthetic aperture radar (SAR) image its noisy appearance. The probability distribution of speckle noise is multiplicative rather than additive, which makes the ...
