Experimental Studies on a Compact Storage Scheme

چکیده
Wavelet transforms, when combined with quantization and a suitable encoding, can be used to compress images eeectively. In order to use them for image library systems, a compact storage scheme for quantized coeecient wavelet data must be developed with a support for fast subregion retrieval. We have designed such a scheme and in this paper we provide experimental studies to demonstrate that it achieves good image compression ratios, while providing a natural indexing mechanism that facilitates fast retrieval of portions of the image at various resolutions.

متن کاملA Cost-Effective Scheme To Improve Radial Tracking Performance For Higher Speed Optical Disc Drives
The periodic disturbances caused by the inherent eccentricity and unbalancing in compact disc systems is one of the prominent radial-tracking problems in high-speed and high-density optical storage systems. To compensate these periodic disturbances, an adaptive feedforward compensation technique is presented and investigated with the aim to have cost-effective optical disc drive manufacturing. ...
متن کاملFourth-order numerical solution of a fractional PDE with the nonlinear source term in the electroanalytical chemistry
The aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (PDE) in the electroanalytical chemistry. The space fractional derivative is described in the Riemann-Liouville sense. In the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the Grunwald- Letnikov discretization of the Ri...
متن کاملA two-step high-order compact scheme for the Laplacian operator and its implementation in an explicit method for integrating the nonlinear Schrödinger equation
We describe and test an easy-to-implement two-step high-order compact (2SHOC) scheme for the Laplacian operator and its implementation into an explicit finite-difference scheme for simulating the nonlinear Schrödinger equation (NLSE). Our method relies on a compact ‘double-differencing’ which is shown to be computationally equivalent to standard fourth-order non-compact schemes. Through numeric...
