A novel reconstruction method for compressive spectral imaging is designed by assuming that the spectral image of interest is sufficiently smooth on a collection of graphs. Since the graphs are not known in advance, we propose to infer them from a pa

Compressive multispectral imaging systems comprise a new generation of spectral imagers that capture coded projections of a scene where spectral data cubes are reconstructed computationally. Separately, time-of-flight (ToF) cameras obtain 2D range im

In this paper, we address the problem of sampling on graphs for change detection in large multi-spectral (MS) and synthetic aperture radar (SAR) images by proposing a graph-based data-driven framework. The main steps of the proposed approach are: (i)

Compressive spectral imaging reconstruction is performed using smoothness on graphs. In doing so, a highly effective and paralilizable graph-smoothness prior reconstruction algorithm is developed based on simple direct matrix inversion.

Non-destructive testing (NDT) refers to inspection methods employed to assess a material specimen without impairing its future usefulness. An important type of these methods is infrared (IR) for NDT (IRNDT), which employs the heat emitted by bodies/o

The estimation of heat conduction properties has considerable importance in the characterization of bamboo with respect to its potential use as an alternative construction material. Even though traditional methods such as hot plates have successfully

Quantitative Pulsed Phase Thermography (PPT) has been only used to estimate defect parameters such as depth and thermal resistance. Here, we propose a thermal quadrupole based method that extends quantitative pulsed phase thermography. This approach
