Abstract :
A method for colour image restoration is discussed. The restoration of images degraded by uniform motion blur and additive white noise is studied and least squares (Wiener) solution is used. The correlations between the components of the colour image is taken into account. The implementation of the filter is carried out in the spatial domain. The advantage of the method is the relatively small support region of the filter and its relatively low computational load
