| Abstract: |
| In order to find the corrosion protection grade of the nickel coating exactly, the computer image processing techniques were used to detect corrosion features in nickel coating. The methods included the nickel coating image collecting, image preprocessing, image binarization, area calculation of corrosion features in nickel coating , the algorithm of computer image processing on corrosion protection test was studied, and simulative experiment on the algorithm based on MATLAB was introduced, then the corrosion feature area parameters was used to calculate corrosion protection grade. This method provided a new basis to nickel coating protection grade rating. |
