Local Directional Pattern (LDP) for face recognition
Taskeed Jabid, Md. Hasanul Kabir, Oksam Chae · 2010
This paper presents a novel local feature descriptor, the local directional pattern (LDP), for recognizing human face. A LDP feature is obtained by computing the edge response values in all eight directions at each pixel position and generating a code from the relative strength magnitude. Each face is represented as a collection of LDP codes for the recognition process.
