| 摘 要： | 压缩成像是压缩传感理论的重要应用领域之一,可以用比Nyquist测量数目少的测量值捕获充分信息重建稀疏或可压缩图像.在研究现有的压缩成像方法的基础上,给出一种新的循环-托普利兹块相位掩模矩阵可压缩双透镜成像方法.模拟实验结果表明新的相位掩模矩阵成像方法可以在欠采样的情况下有效地获得图像信息来重建原始图像.新方法的研究为...

| Abstract: | Compressive imaging is an important application of the theory of compressive sensing,which can capture sufficient information of sparse/compressible image for reconstruction with fewer measurements than Nyquist samples.Taking advantage of the existing compressive imaging methods,a novel method-compressive double-lens imaging using circulant-Toeplitz-block phase mask is proposed.Simulation results show that the novel phase mask matrices imaging method can effectively capture the information of image for imag... |
