According to the paper, in order to generate a mask such as the one shown in "mask_l1loss_uniform_rectangles.png", we run an l1 attack on the entire sign. Afterwards, we examined the resulting perturbation and then create a mask, which on focused on some of the areas with the most change. The amount of white area is user defined.

thanks for your answer!! emmm....so may i understand the position of white area is not computed through code, it just depends on empiric of user?
