Streaming video quality dependents in part upon the video encoding process. The Frequency Domain Motion Estimation process is commonly used to accelerate the entire video encoding process. It is used to reduce the encoding time by increasing the Motion Estimation Time Saving. The Combinational-Discrete Cosine Transform consumes most of the time of the Frequency Domain Motion Estimation video en...

In this paper, we present a novel Gabor wavelet based Kernel Entropy Component Analysis (KECA) method by integrating the Gabor wavelet transformation (GWT) of facial images with the KECA method for enhanced face recognition performance. Firstly, from the Gabor wavelet transformed images the most important discriminative desirable facial features characterized by spatial frequency, spatial local...

We reveal three surprising properties of cosine families, distinguishing them from semigroups of operators: (1) A single trajectory of a cosine family is either strongly continuous or not measurable. (2) Pointwise convergence of a sequence of equibounded cosine families implies that the convergence is almost uniform for time in the entire real line; in particular, cosine families cannot be pert...

This text describes the COS method and its implementation for the BENCHOP-project. 1 Fourier cosine expansion formula (COS formula) We explain the COS method to approximate the European option value u(x, t0) = e −r∆tE [u(XT , T )|Xt0 = x] , (1) with ∆t = T − t0. Here Xt is the state process, which can be any monotone function of the underlying asset price St, for example, the scaled log-asset p...

Objective type of Examination evaluation is easy in Computer world. But the descriptive type of question evaluation is more difficult and there is no significant research has been taken place. In this paper I propose a new solution to the above problem with text classification using the new fuzzy logic named CosFuzzy Logic. Document Clustering is a useful technique that organizes a large quanti...

The diversity created during the searching process in swarm intelligence algorithms plays an important part that affects the exploration ability. The searching result can be further improved if the algorithm gives consideration to both the exploitation and the exploration. In this paper, the evolved bat algorithm is improved by replacing the fixed value, which is determined by the media, with a...
