Unnatural L0 sparse representation … WebOne of our future work is to apply flash deblurring on images with non-uniform blur. This is a intuitive extension of our robust flash deblurring method. Considering the projective motion blur model [27, 67, 72], we can easily incorporate our flash gradient constraint with the model and formulate the deblurring problem as a MAP problem.
