Application of the Karhunen-Loeve Procedure for the Characterization of Human Faces
نویسندگان
چکیده
The exploitation of natural symmetries (mirror images) in a well-defined family of patterns (human faces) is discussed within the framework of the Karhunen-L&ve expansion. This results in an extension of the data and imposes even and odd symmetry on the eigenfunctions of the covariance matrix, without increasing the complexity of the calculation. The resulting approximation of faces projected from outside of the data set onto this optimal basis is improved on average.

Robust Face Recognition Using Eigen Faces and Karhunen-Loeve Algorithm
The current research paper is an implementation of Eigen Faces and Karhunen-Loeve Algorithm for face recognition. The designed program works in a manner where a unique identification number is given to each face under trial. These faces are kept in a database from where any particular face can be matched and found out of the available test faces. The Karhunen –Loeve Algorithm has been implement...
متن کاملA Karhunen Loeve analysis of episodic phenomena
We consider a spatio temporal extension of the classical Karhunen Loeve KL procedure which is well suited to episodic phenomena As an application of the novel technique we consider the activity of the human heart as recorded by echocardiography A direct application of KL shows that O modes account for the full activity The comple mentary temporal activity of these modes then furnishes an intere...
متن کاملCompression of image clusters using Karhunen Loeve transformations
This paper proposes to extend the Karhunen-Loeve compression algorithm to multiple images. The resulting algorithm is compared against single-image Karhunen Loeve as well as algorithms based on the Discrete Cosine Transformation (DCT). Futhermore, various methods for obtaining compressable clusters from large image databases are evaluated.

متن کاملModel Reduction, Centering, and the Karhunen-Loeve Expansion
We propose a new computationally efficient modeling method that captures existing translation symmetry in a system. To obtain a low order approximate system of ODEs prior to performing Karhunen Loeve expansion we process the available data set using a “centering” procedure. This approach has been shown to be efficient in nonlinear scalar wave equations.
