Also Coiflet Wavelet performs better than Symlet, Haar and Daubechies wavelets. The proposed Orthonormal wavelet transform OWT method has minimum Mean Square and highest PSNR with Coif let wavelets. Simulation results shows that denoised image is 98.29 similar for 5 dB noise standard deviation and 84.42 similar for 30 dB noise standard deviation. The proposed method has 1.35 dB and 4 improvement for s =10 dB, 2.08 dB and 7 improvement for s =20 dB and 2.26 dB and 9 improvement for s =30 dB as compared to denoising with two thresholds for edge detection 1 .
