CORRELATIONS BETWEEN WAVELET IMAGE FEATURES AND CORROSION PARAMETERS FOR CARBON STEEL CORRODED IN SOIL
|
Abstract:
First,use a scanner to acquire corrosion images of samples;second,apply two-dimension discrete wavelet transform to decompose the images in three-level,whilst L1 norm,energy and entropy of sub-images are extracted as texture features of the images;then the anisotropy of texture feature in the same level is calculated;finally,the correlations between the anisotropy of texture features and corrosion parameters are studied by multivariate linear regression.The result shows that there is a good linear relations...
