| Abstract: | Scanner is used to acquire corrosion images of carbon steel and low-alloy steel in seawater and in order to show the corrosion modality clearly the images are pre-processed by filter and histogram equilibrium methods. The wavelet transform was used to analysis the image and energy feature was extracted from every subimages. Relativity between the acquired features and corrosion data of metallic materials in seawater was studied and a good result was received. |
