METHOD FOR RECONSTRUCTING AN IMAGE FROM A SET OF PROJECTIONS BY APPLYING A WAVELET TRANSFORM

摘要

The method seeks to reduce the calculation required to invert the projection measurements. An important part of this is achieved by filiations established between the same shapes at different scales. For the mini-images (DH1,DH2,DH3) three equivalent portions (J1,J2,J3) occupy the same relative positions. If the smallest (J3) is insignificant relative to a threshold then the equivalents (J2,J3) may also be ignored
