摘要：The recording and transfer rates of digital imaging systems can not keep abreast of the actual captured amount of data.Because the compression rates of standard loss-less techniques are still too low, lossy techniques like the well-knownJPEG or a new method based upon wavelets have to be taken into account. In order to study the decrease in imagequality the effect of these methods will be examined with respect to the geometrical accuracy and the information content– both using manual as well automatic processing methods
