Texture analysis and classification with tree-structured wavelet transform

Texture analysis and classification with tree-structured wavelet transform

A multiresolution approach based on a modified wavelet transform called the tree-structured wavelet transform or wavelet packets is proposed. The development of this transform is motivated by the observation that a large class of natural textures can be modeled as quasi-periodic signals whose dominant frequencies are located in the middle frequency channels. With the transform, it is possible t...

Texture Classification Using Tree-structured Wavelet Transform and Neural Networks

In this paper a new approach for texture classification problem is presented. Tree-structured wavelet transform for the pre-processing task while the neural network is used for the classification task. The energy values obtained at the subbands are used for the input vector of the neural network system. The subbands where the energy values are greater than a threshold are determined and it is t...

Multiscale texture classification using dual-tree complex wavelet transform

This paper presents a multiscale texture classifier that exploits the Gabor-like properties of the dual-tree complex wavelet transform, shift invariance and 6 directional subbands at each scale, and uses a feature vector comprising of a variance and an entropy at different scales of each of the directional subbands. Experimental results demonstrate its robustness against noise and a higher clas...
