Abstract :
The wavelet transform has become a popular tool in many applications, including image processing, especially in removing noise from images. This paper presents a modified Donoho´s (1995) thresholding for denoising images. The simulation results showed that modified thresholding is superior in terms of PSNR compared to Donoho´s thresholding
