压缩感知(Compressed Sensing
CS)的信号重构部分需要进行大数据量的计算
然而传统的CPU对大量的矢量计算并没有优势.为了解决这一问题
我们以CUDA作为并行计算架构
通过GPU-CPU并行编程技术
实现了三种快速高效的压缩感知图像恢复算法
包括正交匹配追踪OMP算法、两步阈值迭代TwIST算法和线性Bregman算法.
The signal reconstruction in compressive sensing (CS) requires a large amount of data processing. However the traditional CPU has no advantage on vector calculation. To deal with this issue
we design a parallel computing architecture using CUDA. Based on GPU-CPU parallel programming technology
and we realize three fast and efficient CS image reconstruction algorithms
including OMP
TwIST
and linear Bregman algorithm.
