An improved Edge Adaptive Grid technique is proposed to authenticate grey scale images through Contour Tracer. Contour tracer is used to selects the good Data Carrying Pixel Locations associated with L-shape patterns. By maintaining and updating a location status map, a protective mechanism is applied to preserve the context of each DCPL and their. Threshold decomposition is of particular importance in WM smoothing since they are commutable operations. That is, applying a WM smoother to a 2M + 1 valued signal is equivalent to decomposing the signal to 2M binary thresholded signals, processing each binary signal separately with the corresponding WM smoother, and then adding the binary outputs together to obtain the integer-valued output.
