Organized investigation of the influence of the compression algorithm Wavelet (the standard JPEG-2000) on statistical features of the images. Input image was prototyped as additive amount of the deterministic signal of the constant amplitude and noise, complying by the Poisson law. Produced estimation of average, dispersions and relations signal oise for signal components, noise components and image. Shown that using the algorithm of the image compression changes the statistics of the noise and statistical features of the image. Herewith exists the growing a relations signal oise that can be explained filtering properties of the algorithm on high frequency.
