Image denoising is being a governing field in image processing. Image denoising is applied before any image processing and information extraction algorithm on image. In this paper Non Local Means (NLM) algorithm is applied based on Curvelet Transformation. This NLM algorithm is modified to include energy of the reconstructed images to improve PSNR. The modified algorithm is compared with traditional NLM based on Curvelet transformation and results shows that PSNR has considerably improved fordoi:10.17577/ijertv5is030811 fatcat:zavln2zh3zeddgon6hpaajs3oy
