Biorthogonal Quincunx Coifman Wavelets
We de ne and construct a new family of compactly supported, nonseparable two-dimensional wavelets, biorthogonal quincunx Coifman wavelets" BQCWs, from their one-dimensional c...

Covariance of Kinetic Parameter Estimators Based on Time Activity Curve Reconstructions: Preliminary Study on 1D Dynamic Imaging
We provide approximate expressions for the covariance matrix of kinetic parameter estimators based on time activity curve (TAC) reconstructions when TACs are modeled as a linear c...
