In this paper we propose a fast method to convert H.264/AVC Integer Transform (IT) coefficients to Discrete Cosine Transform (DCT) coefficients for applications in video transcoding. We derive the transform kernel matrix for converting, in the transform domain, four IT coefficient blocks into one 8 8 × DCT block of coefficients. By exploiting the symmetry of this matrix, we show that the propos...

In this paper, the reduced differential transform method (RDTM) is applied to various nonlinear evolution equations, Korteweg–de Vries Burgers' (KdVB) equation, Drinefel’d–Sokolov–Wilson equations, coupled Burgers equations and modified Boussinesq equation. Approximate solutions obtained by the RDTM are compared with the exact solutions. The present results are in good agreement with the exact ...

The numerical results show that this method is a powerful tool for solving nonlinear PDEs a...

The explicit use of partial di erential equations (PDE's) in image processing became a major topic of study in the last years. In this work we present an algorithm for histogram modi cation via PDE's. We show that the histogram can be modi ed to achieve any given distribution. The modi cation can be performed while simultaneously reducing noise. This avoids the noise sharpening e ect in classic...

We discuss the problem of parameter estimation in nonlinear stochastic di€erential equations (SDEs) based on sampled time series. A central message from the theory of integrating SDEs is that there exist in general two time scales, i.e. that of integrating these equations and that of sampling. We argue that therefore, maximum likelihood estimation is computationally extremely expensive. We disc...
