Unified Matrix Treatment of Discrete Transforms
Vlasenko, K.R. Rao · IEEE Transactions on Computers · 1979
An unified matrix treatment is developed for some discrete transforms such as Haar (HT), rationalized Haar (RHT), rapid (RT), modified Wash–Hadamard (MWHT), Hadamard– Haar (HHT)r, and rationalized Hadamard–Haar (RHHT)r. For RT a technique for recovering the data sequence from the transform vector is presented.
