摘要：
The three-dimensional discrete Hartley transform (3-D DHT) has been applied in a wide range of 3-D applications such as 3-D power spectrum analysis, 3-D filtering, and medical applications, etc. In this paper, a three-dimensional algorithm for fast computation of the three-dimensional discrete Hartley transform is developed. The mathematical concept and derivation is presented and the arithmetic complexity is analysed and compared to the familiar row-column approach. It is found that this algorithm offers substantial savings in both the number of multiplications and additions. (C) 2002 Elsevier Science B.V. All rights reserved.
