X-ray computed tomography (CT) is a noninvasive process for acquiring 3D images from the internal structure of an object. Traditionally, the number of samples needed to recover images from X-ray projections is due to the Nyquist criteria. Recently, a sampling protocol based on compressive sampling (CS) theory has been proposed for reducing the number of required samples. The compressive CT system...
The Coded Aperture Snapshot Spectral Imaging system (CASSI) is a remarkable architecture based on CS theory which senses the spectral scene by using two-dimensional coded focal plane array (FPA) projections. The CASSI system can be characterized by a measurement matrix which can be designed according to the requirements of a particular issue. Traditional approaches require recovering all the data...
