The nonsubsampled contourlet transform (NSCT) is a new multi-resolution transform, which can give an asymptotic representation of edges and contours in image by virtue of its characteristics of multi-direction, flexible multi-scale and shift-invariant simultaneity. For fusion between visible light image and infrared image, this paper proposed a new method(More)
In this paper, a multi-focus image fusion method based on the weighted non-negative matrix factorization and focal point analysis is presented to improve image fusion method based on non-negative matrix factorization. The relationship among the point spread function, the optical system and imaging processing is analyzed in the method, then a weighted matrix(More)
