Classification of Texture Rotation-Invariant in Images Using Feature Distributions
B. Ramesh, B. Shadaksharappa, Suryakanth V. Gangashetty · 2007
A distribution-based classification approach and a set of developed texture measures are applied to rotation-invariant texture classification. The performance is compared to that obtained with the well-known circular-symmetric autoregressive random field (CSAR) model approach. A difficult classification problem of 15 different Brodatz textures and seven rotation angles is used in experiments. The results show much better performance for our approach than for the CSAR features. A detailed analysis of the confusion matrices and the rotation angles of misclassified samples produces several interesting observations about the classification problem and the features used in this study.
