Quaternionic extended local binary pattern with adaptive structural pyramid pooling for color image representation

作者：

Highlights：

• We propose a quaternionic extended local binary pattern for color image representation.

• We propose an extended quaternionic representation by introducing an information term into the real part of a quaternion.

• We propose adaptive structural pyramid pooling to aggregate encoded features into histogram representations.

• Our method achieves the state-of-the-art results for color texture classification and scene categorization.
