Abstract: matlab paper displays performance comparison of 3 proposed strategies with orthogonal wavelet alias Cosine, Haar and Walsh wavelet employing Normalization for ‘Color to Gray and Back’. The color information engineering matlab picture is embedded into its gray scale version employing wavelet and normalization strategy. Instead of employing matlab unique colour picture for garage and transmission, gray picture Gray scale version with embedded colour information may also be used, ensuing into larger bandwidth or garage utilization. Among three algorithms considered matlab second algorithm give greater functionality as in comparison to first and third algorithm. In our experimental outcomes second set of rules for DCT wavelet using Normalization offers better functionality in ‘Color to gray and Back’ w. r.
