This paper explores the contributions of all reconstruction combinations of the synthesis delay filters in adaptive synthesis filter banks and their effects on objective performance in image compression. It presents a novel comprehensive approach to manage all reconstruction combinations and their placing configuration in the adaptive synthesis filter(More)
High resolution CARTOSAT-1 satellite with its along track stereo capability has opened a number of applications. With fore and aft images looking at +26° and -5° respectively, the satellite is looking the same terrain forming a stereo pair having spatial resolution 2.5 m and a temporal resolution of, between the pairs, less than a minute. One of the(More)
The aim of this paper is to analyze the performance of adaptive synthesis filter banks for image compression at low bit rates. In adaptive synthesis filter banks, analysis section comprises of linear phase filters whereas, synthesis section manages a combination of linear phase and non linear filters (in form of delay filters). The adaptive synthesis filter(More)
This paper presents enhancement of image reconstruction by comprehensively exploiting the phase diversity of adaptive synthesis filter bank. A novel approach of selection of synthesis delay filters in various reconstruction groups and possible placing configurations of optimal groups in adaptive synthesis filter bank have been explored. In contrast with(More)
Subband coding is an efficient technique in image compression, where the same analysis and synthesis filters (either linear phase or non linear phase) are used in all subband levels. In adaptive synthesis filter banks, analysis section comprises of linear phase filters whereas, synthesis section manages a combination of linear phase and non linear filters(More)
Lactobacillus competent cells are considered important vehicles for electro-transform process and express exogenous DNA. Previously several complex protocols were used for electro-transformation of lactobacillus strains. In the preset study, we evaluated an ameliorate maneuver for the preparation of efficient competent cells of lactobacillus. The parameters(More)
Abstract Tax is a financial charge imposed on individuals by state in different forms like direct tax paid directly by individuals, indirect tax collected by intermediaries and deposited to Government like sales tax. Taxation plays an important role in the process of revenue generation and to run various activities in an economy. The study empirically(More)
The reaction of ethanol has been studied on the surface of rutile TiO(2)(110) by Temperature Programmed Desorption (TPD), online mass spectrometry under UV excitation and photoelectron spectroscopy while the adsorption energies of the molecular and dissociative modes of ethanol were computed using the DFT/GGA method. The most stable configuration is the(More)
The subject of this paper is the design of adaptive synthesis filter bank for enhancement of image reconstruction by exploiting the phase diversity of synthesis filters in subband coding system. This paper for the first time, presents a comprehensive as well as an efficient approach of handling a large number of synthesis filters and reducing the(More)
