Image Processing is any form of signal processing for which the input is an image or video frame; the output of image processing is set of parameters related to the image. The goal of our research presents denoising using various multi-resolution transforms (MRA) such as wavelets, Contourlets and Curvelets. Curvelet based image denoising method is compared with Wavelet denoising and contourlet denoises. The analysis shows that Curvelet performs better than wavelet and contourlet because the no. of co-efficient needed to represent a curve is lesser in Curvelet than Contourlet and then Wavelet. Hence the computational complexity has also been reduced when using Curvelet transform.
Conclusion
In this project, several issues were addressed to improve image denoising and the comparison graph is plotted as shown in fig. 11, from this graph the SNR value for multiresolution analysis technique is calculated. Signal to noise ratio values for various transforms are determined, they are, wavelet transformation SNR value is 10.23, SNR value of Contourlet transformation is 10.99,SNR value of Curvelet transformation is 17.66. By this analysis it can be concluded that Curvelet transform is the best one to reducing noise level from a noisy image.
