基于压缩感知理论的图像重构技术

通过CS理论在工程应用上典型的正交匹配追踪算法,实现了一维信号和二维图像的精确重构,针对该方法中出现对整幅图像进行采样计算时需要大量的观测矩阵存储空间,并且重构过程中耗费了大量的时间等问题,提出了一种基于OMP算法的改进方案,将图像进行分块压缩感知。通过实验分析,以上问题得到了解决,重构图像的质量在没有增加计算复杂度的前提下也得到了提高。

Image Reconstruction Technique Based on the Compressed Sensing Theory

Through the study of the CS theory,this paper realizes the accurate reconstruction of the one-dimensional signal and two-dimensional image by applying the OMP algorithm,which is the classical method in the CS engineering application.As to the problems that large storage of sampling matrix is needed when sampling and calculating the whole image and that a huge amount of time is consumed when reconstructing it,this paper proposes an improvement scheme based on the OMP algorithm,that is,dividing the image into...
