• Empirical study for optimum samples for texture classification and retrieval.
• Empirical study to form nine hybrid feature sets and six non hybrid feature sets.
• Retrieval performance of HWSCF3, HWSCF6, HWSCF7, HWSCF9 feature sets is better.
• A novel texture retrieval method using fuzzy logic classifier is demonstrated.
• Scale and rotation invariant texture retrieval is demonstrated; which is the incomparable work of the author.

A novel approach for content-based texture image retrieval system using fuzzy logic classifier is proposed in this paper. The novelty of this method is demonstrated by handling the complexity issues in texture image retrieval arising from rotation and scale variance. These issues are divided into four groups as non rotated non scaled, rotation invariant, scale invariant and scale and rotation invariant texture retrieval for retrieval performance analysis. Features of texture images are obtained using discrete wavelet transform based statistical features and gray level co-occurrence matrix based co-occurrence features. The fuzzy logic classifier is developed with Gaussian membership function with mean and standard deviations of the features. The retrieval performance improvement is carried out by considering various combinations of the features. The average retrieval rates for the four issues have been achieved at 99.40% with 40 features, 91% with 80 features, 65.2% with 40 features, and 63.4% with 65 features respectively. This method outperforms the existing methods in terms of average retrieval rate. The scale and rotation invariant texture retrieval is an incomparable work that has been demonstrated in the present paper.
