Abstract
In this paper, an overlapping block transform coding for offset-sampled image compression, called OS-OBT, is proposed. First, OS-OBT is developed from the theory of frequency analysis\synthesis. In the second, a fast algorithm for OS-OBT is devised, which is twice faster than the usual DOT. In the last, simulations demonstrate that coding performance of OS-OBT is superior to that of DOT and block artifacts decrease in OS-OBT.
