P. DALY, B.Sc, Ph.D.f Summary: A finite-element method based on a function minimization technique is developed for analysing homogeneous waveguide problems. The continuous eigen-value operator as in the Ritz finite-difference method is replaced by a matrix operator. The resulting equations are, however, matrix eigen-value equations. Relevant properties of the matrices are discussed. It is demon...

Following Futurism, we show how periodic motions can be represented by a small number of eigen-shapes that capture the whole dynamic mechanism of periodic motions. Spectral decomposition of a silhouette of an object in motion serves as a basis for behavior classification by principle component analysis. The boundary contour of the walking dog, for example, is first computed efficiently and accu...

However, it is generally difficult if not impossible to prepare a complete set of a priori noisy environment knowledge. Especially, the noisy environments which are not seen in the training phase (aka unseen noisy environment) may become potential sources of serious performance degradation for those non-blind methods. In other words, it is crucial how to well organize and efficiently utilize th...

the problem of eye detection in face images is very important for a large number of applications ranging from face recognition to gaze tracking. in this paper we propose a new algorithm for eyes detection. first, the face region is extracted from the image by skin-color information. second, horizontal projection in image is used to approximate region of the eye be obtained . at last, the eye ce...

The variational method for numerical simulation of rf parameters of periodical structures with arbitrary phase shift per structure period is developed. At any phase shift the field distribution is represented as a sum over trial functions. As trial functions we use numerically simulated field distribution, considering with different boundary conditions only one structure period. By using standa...
