Boundary Contour System forDynamic Compression andImageEdgeEnhancement
S. H. Krishna Veni, A. Narayanan Kutty · 2005
TheBoundary Contour System (BCS)provides a powerful technique torecognize patterns andrestore image quality underexcessive fixed pattern noise asinSynthetic Aperture Radar(SAR) images. Thispaper describes theVLSI design ofthecircuits needed forpreprocessing stages ofBCS (i.e.) preprocessing noisy image data that vary inintensity over asmuchasfourorders ofmagnitude. Thecircuits arebased on equations representing astage oneofaBCS.Thepreprocessing stages havebeendesigned using cadence spectre IC5tool. The stage onemodelcircuits withIDarray of20nodecells is designed whichheredemonstrates thedynamicrange compression andtheresponses toinput stiniuli fromthelinear array ofcircuits illustrate edge enhancement.
