Dynamic measurement rate allocation for distributed compressive video sensing
We address an important issue of fully low-cost and low-complexity video encoding for use in resource limited sensors/devices. Conventional distributed video coding (DVC) does not actually meet this requirement because the acquisition of video sequences still relies on the high-cost mechanism (sampling + compression). Recently, we have proposed a distributed compressive video sensing (DCVS) fra...
متن کاملTEM Video Compressive Sensing
One of the main limitations of imaging at high spatial and temporal resolution during in-situ TEM experiments is the frame rate of the camera being used to image the dynamic process. While the recent development of direct detectors has provided the hardware to achieve frame rates approaching 0.1ms, the cameras are expensive and must replace existing detectors. In this paper, we examine the use ...
متن کاملBlind compressive sensing dynamic MRI with sparse dictionaries
Each row shows few spatial frames and the image time profile. We observe a similar behavior as seen in fig.1. k-t FOCUSS showed some temporal blur (see yellow arrow in (b)). BCS had better temporal fidelity but suffered from noisy artifacts (see arrows in (c) due to learning noisy patterns. Sparse BCS resulted in reconstructions with reduced noise like artifacts without compromising on the spat...
متن کاملCompressive Sensing in diffusion MRI
This thesis is dedicated to the development of new acquisition and processing methods in diffusion MRI (dMRI) to characterize the diffusion of water molecules in white matter fiber bundles at the scale of a voxel. In particular, we focus our attention on the accurate recovery of the Ensemble Average Propagator (EAP), which represents the full 3D displacement of water molecule diffusion. Diffusi...

σ using both SENSE and the hybrid CS+SENSE methods. Note that the clear optimality peak in the CS result. (c) Plot of the upper bound derived in (5) showing that the probability that μ(E) exceeds some threshold is minimal at roughly the same configuration yielding optimal SNR in (b). (d) Monte Carlo simulation of μ(E) for 1000 random Fourier trials at each value of σ. Note that the coil configu...
