Video 68: Texture Classification using LBP

 

Hello viewers. In this video, a very popular texture descriptor Local Binary Pattern (LBP) is utilized for texture classification. For classification, three very popular databases are considered, Surotex, Kyberge and FourShapes. The classification task is fully implemented in MATLAB and simulation results show the strength of LBP as feature vector. This video has following contents.

• Introduction to Local Binary Pattern (LBP).
• Image databases used.
• Training and testing procedures.
• Implementation in MATLAB (MATLAB Code).
• Simulation outcomes.
