Local Concave-and-Convex Micro-Structure Patterns for texture classification

作者:

Highlights:

• A formal definition of Concave and Convex Binary Thresholding Functions are introduced.

• Two new LBP-like descriptors: Local Concave and Convex Micro-Structures Pattern (LCvMSP and LCxMSP) descriptors are proposed.

• LCvMSP and LCxMSP are concatened into a single vector feature to obtain the multiscale LCCMSP descriptor.

• A statistical hypothesis testing based method for parameters optimization on several datasets is proposed.

• The proposed methods demonstrate superior performance to 79 LBP variants and non-LBP methods over 13 texture datasets.
