Looks like you've already accepted an answer so I guess you got it figured out. But here is where I'd refer you:
Fast local Laplacian filtering of images
B = locallapfilt(I,sigma,alpha) filters the grayscale or RGB image I with an edge-aware, fast local Laplacian filter. sigma characterizes the amplitude of edges in I. alpha controls smoothing of details.
B = locallapfilt(I,sigma,alpha,beta) filters the image using beta to control the dynamic range of A.
