We have optimized the MATLAB function imreconstruct of Image Processing Toolbox writing a mex function to reduce the execution time of Vincent's algorithm. Imreconstruct is called by the following functions:imclearborder, imextendedmax, imextendedmin, imfill, imhmax, imhmin, imimposemin.

Best results were obtained for matrices up to 2048^2 pixels: with a greater number of pixels the execution time of our algorithm converges to MATLAB's one. Tipically our codes run 2-3 times faster than imreconstruct function.
