3-D Face Recognition Using Improved 3D Mixed Transform

This paper deals with the using of Improved 3D Mixed Transform (3D-IMT) for face recognitionproblem. The mixed transform consists Fourier based 3D radon transform plus 1-D Wavelettransform (which is also known as 3D Ridgelet transform). The Mixed Transform is improved byusing the Particle swarm optimization ( PSO) technique. The improvement involves the selectionof the best of directions for smart rectangle-to-polar transform as a part of the 3D RadonTransformation. The 3D-IMT is applied to the 3D representation of face images, and yields a fewnumber of features, these features is projected into the maximized projection that achieves goodrecognition rate using the Linear Discriminant Analysis (LDA).
