Local adaptive image processing in a sliding transform domain
Jacobo Gomez-Agis, Vitaly Kober · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
A local adaptive image processing on a sliding discrete transform is presented. The local restoration technique is performed by pointwise modification of local discrete transform coefficients. To provide image processing at a high rate, a fast recursive algorithm for computing the sliding transform is utilized. The algorithm is based on a recursive relationship between three subsequent local spectra. Computer simulation results using real images are provided and compared with that of common restoration techniques.
