T2-FDL: A robust sparse representation method using adaptive type-2 fuzzy dictionary learning for medical image classification

作者:

Highlights:

• A robust sparse representation method is proposed for image classification.

• A type-2 fuzzy system is used to learn dictionary items efficiently.

• The robust dictionary learning method can reduce the effect of uncertainties.

• Two well-known brain tumor image databases are used to evaluate the proposed method.

• Substantial improvement in terms of accuracy, sensitivity, and specificity observed.
