System Calibration and Statistical Image Reconstruction for Ultra-High Resolution Stationary Pinhole SPECT
For multi-pinhole SPECT, iterative reconstruction algorithms are preferred over analytical methods, because of the often complex multi-pinhole geometries and the ability of iterat...

Statistical Substring Reduction in Linear Time
We study the problem of efficiently removing equal frequency n-gram substrings from an n-gram set, formally called Statistical Substring Reduction (SSR). SSR is a useful operatio...
