    Segmentation of digital microscopy data for the analysis of defect structures in materials using nonlinear diffusions
    Download  cobweb.ecn.purdue.edu
    We apply stabilized inverse diffusion equations (SIDEs) to segment microscopy images of materials to aid in analysis of defects. We extend SIDE segmentation methods and demonstrat...

    Fast space-varying convolution and its application in stray light reduction
    Download  engineering.purdue.edu
    Space-varying convolution often arises in the modeling or restoration of images captured by optical imaging systems. For example, in applications such as microscopy or photography...

    Multi-object segmentation using coupled nonparametric shape and relative pose priors
    Download  www.cs.technion.ac.il
    We present a new method for multi-object segmentation in a maximum a posteriori estimation framework. Our method is motivated by the observation that neighboring or coupling objec...

    Wavelet-based Poisson rate estimation using the Skellam distribution
    13 years 11 months ago
    Wavelet-based Poisson rate estimation using the Skellam distribution
    Download  sisl.seas.harvard.edu
    Owing to the stochastic nature of discrete processes such as photon counts in imaging, real-world data measurements often exhibit heteroscedastic behavior. In particular, time ser...

    Dantzig selector homotopy with dynamic measurements
    Download  users.ece.gatech.edu
    The Dantzig selector is a near ideal estimator for recovery of sparse signals from linear measurements in the presence of noise. It is a convex optimization problem which can be r...
