                         monochromatic image is the solution of the heat equation using 
                         that image as an initial condition. Alternatively, this linear 
                         scale space can also be obtained applying Gaussian filters of 
                         increasing variances to the original image. In this work, we 
                         compare (by looking at theoretical properties, running time and 
                         output differences) three ways of discretizing this Gaussian 
                         scale-space: sampling Gaussian distributions; approximating by 
                         first-order generators; and finally, by a new method we call 
                         {"}Crossed Convolutions{"}.In particular, we explicity present a 
                         corret way of initializing the recursive method approximate
