Helmi Zulhaidi Mohd Shafri — 2006-06-17

American Journal of Applied Sciences, Published online: 17 June 2006; doi:10.3844/ajassp.2006.1864.1871

Two red edge position (REP) techniques, Linear and Lagrangian, were applied on hyperspectral data acquired from the HyMap sensor for a forested area in Thetford Forest, UK. Red edge positions of diffe...

Face Recognition using Eigenfaces and Neural Networks

Mohamed Rizon — 2006-06-30

American Journal of Applied Sciences, Published online: 30 June 2006; doi:10.3844/ajassp.2006.1872.1875

In this study, we develop a computational model to identify the face of an unknown person’s by applying eigenfaces. The eigenfaces has been applied to extract the basic face of the human face images...

Object Detection using Geometric Invariant Moment

Mohamed Rizon — 2006-10-30

American Journal of Applied Sciences, Published online: 30 October 2006; doi:10.3844/ajassp.2006.1876.1878

Geometric moment invariant produces a set of feature vectors that are invariant under shifting, scaling and rotation. The technique is widely used to extract the global features for pattern recognitio...
