VLSI Implementation of Adaptive Edge Enhanced Image Scalar Using ETA Adder

A low complexity adaptive edge enhanced algorithm will be used for the implementation of 2D-image scaling application. It consists of linear space variant edge detector, a low complexity sharpening spatial filter and a simplified bilinear interpolation. The adaptive technology is used to enhance the effect of the edge detector by adaptively selecting the input pixels of the bilinear interpolation. The edge detector is designed to discover the image edges by a low-cost edge-catching technique. The sharpening spatial filter is added as a pre-filter to reduce the blurring effect produced by the bilinear interpolation.
