Wavelet transforms have become one of the most important and powerful tool of signal representation. Nowadays, it has been used in image processing, data compression, and signal processing. Here, we are discussing about the basic concept for Wavelet Transforms and the fast algorithm of Wavelet Transform. Now-a-days the wavelet theorems make up very popular methods of image processing, de-noising and compression. Considering that the Haar functions are the simplest wavelets, these forms are used in many methods of discrete image transforms and processing. The image transform theory is a well known area characterized by a precise mathematical background, but in many cases some transforms have particular properties which are not still investigated. This paper for the first time presents graphic dependences between the types of wavelet approaches for de-noising. Some properties of the Haar, Daubechies 1 and 2, coif-let 1 and 5, Symlet-8 and reverse bi-orthogonal wavelets spectrum were investigated. Here, i am using different types of wavelet approaches for finding the Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR) based approach for de-noising the image. For removing the noise from the image wavelet techniques gives good improvement in recovering the original image. Result will shows the recovery of original images along with noisy images.
