MATLAB Implementation of High-Pass Gaussian Filtering with LBP and LDP

MATLAB source codes for High-Pass Gaussian Filtering, Local Binary Patterns (LBP), and Local Derivative Patterns (LDP) for image enhancement and feature extraction applications.

Implementation of LDP Histogram Calculation Based on B Zhang's Research

This code implements the Local Derivative Pattern (LDP) histogram computation algorithm based on the research by B Zhang, Y Gao, S Zhao and J Liu, as published in IEEE Transactions on Image Processing, February 2010, Volume 19, Issue 2. The implementation focuses on high-order local pattern descriptors for face recognition applications, providing an advanced alternative to traditional Local Binary Pattern (LBP) methods.
