Abstract

 

Investigation results of a scaling method for digital images based on discrete wavelet transform (DWT) are presented. Estimates of image distortions under image interpolation using the DWT are obtained. Influence of the basis wavelets choice on the transform errors of images under scaling is investigated. 


Keywords: scaling, image interpolation, discrete wavelet transform.
