Abstract To realize high‐quality image transmission and storage, it is important to reduce the effects of the impulsive noise and the image data erasure produced in the transmission and storage. This paper proposes a new method for image noise suppression using the smearing‐desmearing transform. The smearing‐desmearing transform retains the power spectrum of the image signal and can be applied to the highly efficient coding. the basic principle for the image noise suppression using the smearing‐desmearing transform is shown and the construction of the suitable smearing‐desmearing transform is presented. Then, it is shown that the noise suppression performance of the image noise suppression method based on the smearing‐desmearing transform depends on the variance of the noise, even if there exist the same number of noises. Based on such a property, a method to suppress the burst noise in the image based on the interleaving‐deinter‐leaving and smearing‐desmearing transform is proposed where the smearing‐desmearing transform is applied after spreading the burst noise to fit to the image noise suppression process. Finally, by a computer experiment, it is shown that the proposed method has an excellent effect in image noise suppression.
