Low-complexity Multidimensional DCT Approximations
V. A. Coutinho, R. J. Cintra, F. M. Bayer
In this paper, we introduce low-complexity multidimensional discrete cosine transform (DCT) approximations. Three dimensional DCT (3D DCT) approximations are formalized in terms of…

Low-complexity Three-dimensional Discrete Hartley Transform Approximations for Medical Image Compression
V. A. Coutinho, F. M. Bayer, R. J. Cintra
The discrete Hartley transform (DHT) is a useful tool for medical image coding. The three-dimensional DHT (3D DHT) can be employed to compress medical image data, such as magnetic…
