Grayscale Dilation and Erosion Description

A very fast implementation for grayscale erosion and dilation. We have optimized execution time of grayscale erosion and dilation. Our functions take advantage of MATLAB’s decomposition of structuring elements. graydil(im,se) to perform dilation im is the input 2D matrix (uin8, uint16, uint32 or double) se the structuring element (logical or strel) Memory management is not optimized ( our routines can generateoverflow memory error) but execution time is 2, 3, 4 or 5 times smaller than MATLAB’s one.
