The present invention provides a system and method for compression of image data while preserving the usable information and eliminating or reducing associated noise in which the image data includes a signal and noise. The image data is transformed using a multiscale transform technique (such as the Pyramidal Median Transform) such that the image data is represented as a plurality of transform coefficients each having a corresponding weight. From the respective weights, those transform coefficients associated with noise are determined and extracted from the original plurality of transform coefficients. The remaining transform coefficients are subsequently quantized and coded.
