Compressive imaging using fast transform coding
We propose deterministic sampling strategies for compressive imaging based on Delsarte-Goethals frames. We show that these sampling strategies result in multi-scale measurements which can be related to the 2D Haar wavelet transform. We demonstrate the effectiveness of our proposed strategies through numerical experiments.
متن کاملCompressive Acquisition of Dynamic Scenes
Compressive sensing (CS) enables the acquisition and recovery of sparse signals and images at sampling rates significantly below the classical Nyquist rate. Despite significant progress in the theory and methods of CS, little headway has been made in compressive video acquisition and recovery. Video CS is complicated by the ephemeral nature of dynamic events, which makes direct extensions of st...
متن کاملDynamic Range and Compressive Sensing Acquisition Receivers
Compressive sensing (CS) exploits the sparsity present in many signal environments to reduce the number of measurements needed for digital acquisition and processing. We have previously introduced the concept and feasibility of using CS techniques to build a wideband signal acquisition systems. This paper extends that work to examine such a receiver’s performance as a function of several key de...
متن کاملFast EPR Imaging Using Spinning Magnetic Field Gradient
INTRODUCTION Electron paramagnetic resonance imaging (EPRI) has achieved remarkable progress in the last decades and has many useful and unique applications in the fields of biology and medicine [1-3]. However, the long imaging time prevents the use of this technique in many biological applications where the free radicals have a short intrinsic lifetime or rapid metabolic clearance. Therefore, ...
متن کاملFast 3D EPR Imaging Using Spiral Magnetic Field Gradient
We report a fast 3D continuous wave (CW) electron paramagnetic resonance imaging (EPRI) technique using spiral magnetic field gradient. By spiraling the magnetic field gradient and stepping the main magnetic field, this approach acquired a 3D image in one sweep of the main magnetic field, enabling significant reduction of the imaging time. We demonstrated using a home-built L-band EPR system th...
