Abstract : A fast direct method for obtaining the length-N discrete Hartley transform (DHT) coefficients from three adjacent length-N/3 DHT coefficients is presented. The proposed method reduces significantly the number of arithmetic operations compared to the traditional approach. Furthermore, it is easy to implement.

Keywords : compressed-domain processing discrete Hartley transform fast algorithm
