Low-Complexity Loeffler DCT Approximations for Image and Video Coding
D. F. G. Coelho, R. J. Cintra, F. M. Bayer +6
This paper introduced a matrix parametrization method based on the Loeffler discrete cosine transform (DCT) algorithm. As a result, a new class of eight-point DCT approximations wa…

Block-Parallel Systolic-Array Architecture for 2-D NTT-based Fragile Watermark Embedding
H. P. L. Arjuna Madanayake, R. J. Cintra, V. S. Dimitrov +1
Number-theoretic transforms (NTTs) have been applied in the fragile watermarking of digital images. A block-parallel systolic-array architecture is proposed for watermarking based…
