| Abstract | General results on frame, microlocal analysis, and tight frame wavelets in n are summarized. To perform microlocal analysis of tempered distributions in n , tight frame wavelets, whose Fourier transforms consist of smoothed characteristic functions of squares or sectors of annuli in 2 and cubes in 3 , are constructed. Singularities in smooth images are localized in position and direction by means of the frame coefficients computed in the Fourier domain by using Plancherel’s theorem. |
