To find the unknown value u(x, ), the forward Euler method uses the known values at three other nodes: u(x- x, - ), u(x, - ), and u(x+ x, - ). That is, the values required are those from the previous time step at the corresponding node in space, and both of the adjacent spatial nodes.

For any N output columns, the number of modifications to the entire group of histograms per row is (N^2 + 4r + 1) / N. The paper claims that the minimal N can be solved to equal roughly 2*sqrt(r). For a filter of radius 16, the ideal N becomes 9 (it’s easiest to keep N odd), meaning only four partial histograms are maintained on either side ...
