Abstract: Watershed segmentation is a region based segmentation algorithm. It forms the peak joining two catchment basins containing regional minima. Watershed segmentation is more sensitive to noise and can leads to serious over-segmentation. In order to overcome the shortcomings of traditional watershed segmentation, this paper deals with marker controlled watershed algorithm based on connected components approach locating a regional minima. Mostly the watershed segmentation result in over-segmentation. The markers based watershed segmentation transformation reduces noise and over-segmentation. Watershed has been written in matlab code and also in VHDL hardware descriptive language. The main aim of this project is to implement in a FPGA which requires minimum hardware resources, low execution time and is suitable for use in real time applications.
