<p>Data mapped on a spherical surface is encoded with a format enabling partial resolution and partial distribution. When data mapped on a spherical surface such as an entire circumference image is subjected to the spherical surface wavelet conversion, scaling coefficients and values of wavelet functions are arrayed for each level in the output data. The spatial scalability such as partial distribution or partial resolution can be realized by rearranging the coefficient ck<(j)> in the scaling function PHI k<(j)> and the value dk,m<(j)> of the wavelet function PSI k<(j)> according to positional relations on the spherical surface. <IMAGE></p> |
