Abstract :
This paper presents an algorithm for the fast implementation of 1-D grayscale morphological filters with set structuring elements. The algorithm is developed by filter property analysis, instead of by architecture design. It performs an opening or closing with a single pass procedure. The average number of operations required is less than three comparisons per sample for openings and closings, which is independent of the size of the structuring element used
