In this work to improve the compression scheme, we are interested in image compression by discarding noisy bits from the satellite image and discrete wavelet transform (DWT). This method was tested on various satellite images; this type of compression has allowed us to determine the quality of the reconstructed images (PSNR) and the compression ratio (CR) according to the corresponding of denoising method. A comparative study was conducted to determine the methods leading to the best possible results.
