Barrel Distortion Correction algorithm has been widely used to eliminate the distorted image in the wide angle camera. The distortion occurred due to lens dislocation in the camera. Nowadays, various image Processing algorithm are developed to correct this distortion. In this Proposed work Design of an efficient Architecture for correcting this distortion. The proposed architecture consist of Backward Mapping and linear interpolation units. FPGA family Devices like Cyclone II, Cyclone III, Stratix II and Stratix III are used for verifying the Parameters such as LUT, Power and Time can be measured and compared. The Backward Mapping is done here with linear interpolation. The power consumption and time taken for correcting the distortion is reduced.

Detailed Zeeman studies of nuclear quadrupole resonance of the 35Cl nucleus in a single crystal of 3,4-dichloronitrobenzene have been made. Two resonance frequencies corresponding to the two positions were observed. The crystal class was identified to be tetragonal. From the Zeeman analysis the field gradient directions, minimum number of molecules per unit cell, asymmetry parameter and hence C-Cl bond characters were determined. The equations for molecular planes were also derived using least squares analysis.
