Level set estimation from projection measurements: Performance guarantees and fast computation
Kalyani Krishnamurthy, Waheed U. Bajwa, Rebecca Willett
Estimation of the level set of a function (i.e., regions where the function exceeds some value) is an important problem with applications in digital elevation mapping, medical imag…
A two-stage denoising filter: the preprocessed Yaroslavsky filter
Joseph Salmon, Rebecca Willett, Ery Arias-Castro
This paper describes a simple image noise removal method which combines a preprocessing step with the Yaroslavsky filter for strong numerical, visual, and theoretical performance o…
Changepoint detection for high-dimensional time series with missing data
Yao Xie, Jiaji Huang, Rebecca Willett
This paper describes a novel approach to change-point detection when the observed high-dimensional data may have missing elements. The performance of classical methods for change-p…
Poisson noise reduction with non-local PCA
Joseph Salmon, Zachary Harmany, Charles-Alban Deledalle +1
Photon-limited imaging arises when the number of photons collected by a sensor array is small relative to the number of detector elements. Photon limitations are an important conce…
