Abstract:
A method of scalably encoding shape information on a still image using a wavelet transformation, comprising the steps of:(a) wavelet transforming and scalably encoding shape information on a luminance (Y) component; (b) wavelet encoding texture information on the luminance (Y) component using the shape information on the luminance (Y) component wavelet transformed in the step (a); (c) padding shape information and texture information on a chrominance (UV) component using the shape information on the luminance (Y) component and texture information on the chrominance (UV) component; (d) wavelet transforming and scalably encoding the padded shape information on the chrominance (UV) component; and (e) wavelet encoding the texture information on the chrominance (UV) component using the shape information on the chrominance (UV) component wavelet transformed in the step (d).
