On the Fusion of Compton Scatter and Attenuation Data for Limited-view X-ray Tomographic Applications
Hamideh Rezaee, Brian Tracey, Eric L. Miller
In this paper we demonstrate the utility of fusing energy-resolved observations of Compton scattered photons with traditional attenuation data for the joint recovery of mass densit…
Stabilizing dual-energy X-ray computed tomography reconstructions using patch-based regularization
Brian H. Tracey, Eric L. Miller
Recent years have seen growing interest in exploiting dual- and multi-energy measurements in computed tomography (CT) in order to characterize material properties as well as object…
Blockwise SURE Shrinkage for Non-Local Means
Yue Wu, Brian Tracey, Premkumar Natarajan +1
In this letter, we investigate the shrinkage problem for the non-local means (NLM) image denoising. In particular, we derive the closed-form of the optimal blockwise shrinkage for…
Probabilistic Non-Local Means
Yue Wu, Brian Tracey, Premkumar Natarajan +1
In this paper, we propose a so-called probabilistic non-local means (PNLM) method for image denoising. Our main contributions are: 1) we point out defects of the weight function us…
James-Stein Type Center Pixel Weights for Non-Local Means Image Denoising
Yue Wu, Brian Tracey, Joseph P. Noonan
Non-Local Means (NLM) and variants have been proven to be effective and robust in many image denoising tasks. In this letter, we study the parameter selection problem of center pix…
