Fig. 13.3 CASSI simulation: a image of datacube, b spectral signatures of datacube, and c com-
putational and optical flow describing the numerical processes from the computational and optical
co-design
CASSI reconstruction in Fig. 13.3 . The spectral datacube f consists of alpha-
bet letters “G”, “P”, “Y”, “O” in 2D space and 1D spectrum data. The individual
letters have different intensity distributions in the spectral dimension. In the opti-
cal processing, the datacube f is encoded by the system matrix H , then the CASSI
measurement g is obtained by summing the element-wise multiplied cube over the
spectral dimension.
13.2.2 Image Registration
The goal of high frame rate image (video) stabilization is to remove motion blur
while maintaining high SNR (Signal to Noise Ratio). In practice this can be achieved
