IMAGE MIRRORING AND ROTATION IN THE WAVELET DOMAIN
Theju Jacob, K.R. Rao, Do Nyeon Kim · International Journal of Wavelets Multiresolution and Information Processing · 2010
JPEG2000, the international standard for still image compression, uses wavelet transform. The filters used by JPEG2000 for transformation are the 9/7 Daubechies filter and the 5/3 Le Gall filter. In this paper, we present a method for image mirroring and rotation in the wavelet domain, by manipulating the transformation coefficients. Our technique requires no additional complexity and the perfect reconstruction property is preserved.
