Effect of Hybrid Max Filter and Edge Detection on Scanning Electron Microscope Picture of Calcium Oxide and Copper Oxide Nanocomposites

Abstract

In this present research work, calcium oxide dopped with copper oxide nano structured composite have been prepared through co-precipitation method at constant molar condition of 1:1 (CaO + CuO). The surface topography of the prepared sample has been studied by using field emission scanning electron microscopy (FE - SEM) technique. The obtained SEM results of the prepared CaO + CuO sample reveals the existence of polycrystalline porous topography with a nano structured flower shape. The CaO and CuO crystallites agglomerated with each other and it leads to form a flower shaped structure. The captured SEM images of CaO + CuO samples were investigated by pre-processing technique hybrid max filter is used to analyze the surface topographic information. This image processing approach is used to analyze the image enhancement and edge detected by Sobel and Canny filters. The agglomerated edge of the CaO + CuO sample was successfully analyzed using Sobel and Canny filters.
