This paper discusses removing large objects from digital images and fills the hole that is left behind in a visually plausible way.We present a novel and efficient algorithm that fills the hole by exemplar-based synthesis.Here the simultaneous propagation of texture and structure information is achieved by a single, efficient algorithm.The texture image is repaired by the exemplar -based method; for the structure image, the Laplacian operator is employed to enhance the structure information, and the Laplacian image is inpainted by the exemplar-based algorithm, followed by a reconstruction based on the Poisson equation.To improve the computational efficiency of our algorithm we go for successive elimination algorithm (SEA).In 8 pixel neighborhood method, identifying central pixel value by investigating surrounded 8 neighborhood pixel properties like color variation, repetition, intensity and direction.Finally we compare speed and accuracy of a picture enhancement using 8 pixel neighborhood with exemplar based poisson & successive elimination method
