Özet:

 

Curve and surface thinning are widely-used skeletonization techniques
 for modeling objects in 3 dimensions. In the case of disordered porous media
 analysis, however, neither is really efficient since the internal geometry of the
 object is usually composed of both rod and plate shapes. This paper concludes
 an application of discrete wavelet transform (WT) and complex wavelet
 transform (CWT) in image processing problem such as hybrid skeletonization
 of trabecular bone images. Hybrid skeleton combines 2D surfaces and 1D curve
 to represent respectively the plate-shaped and rod-shaped parts of the object.
 For hybrid skeletonization, two cascade structures are proposed. In these
 structures, features of images were extracted with discrete wavelet transform
 and complex wavelet transform. After that, obtained features were used as 
 inputs of complex-valued artificial neural network (CVANN) which is multilayered
 artificial neural networks with two dimensions (real and imaginary
 parts). Effects of the feature extraction methods are compared for ability of the
 hybrid skeletonization on a trabecular bone sample. Results show that the CWT
 succeeded to hybrid skeletonization with lower error rate than WT.
