Based on the compressive sensing theory (CS), various compressive imaging (CI) systems have been developed. Meanwhile, image fusion methods that directly perform on the measurements from multiple CI sensors are also investigated in literatures. In this paper, we presented a multi-focus image fusion method in compressive sensing domain. The main contribution is to introduce a novel clarity level of the random CI measurements without prior geometric information. The CI measurements are sparsely represented with DCT bases which are also projected ...
