AbstractThe concept of Multi-Scale Transform MST based image de-noising methods is incorporated in this paper. The shortcomings of Fourier transform based methods have been improved using multi-scale transform, which help in providing the local information of non-stationary image at different scales which is indispensable for de-noising. Multi-scale transform based image de-noising methods comprises of Discrete Wavelet Transform DWT, and Stationary Wavelet Transform SWT. Both DWT and SWT techniques are incorporated for the de-noising of standard images. Further, the performance comparison has been noted by using well defined metrics, such as, Root Mean Square Error RMSE, Peak Signal-to-Noise Ratio PSNR and Computation Time CT. The result shows that SWT technique gives better performance as compared to DWT based de-noising technique in terms of both analytical and visual evaluation. |
