Energy-efficient 8-point DCT Approximations: Theory and Hardware Architectures
R. J. Cintra, F. M. Bayer, V. A. Coutinho +2
Due to its remarkable energy compaction properties, the discrete cosine transform (DCT) is employed in a multitude of compression standards, such as JPEG and H.265/HEVC. Several lo…

A Multiplierless Pruned DCT-like Transformation for Image and Video Compression that Requires 10 Additions Only
V. A. Coutinho, R. J. Cintra, F. M. Bayer +2
A multiplierless pruned approximate 8-point discrete cosine transform (DCT) requiring only 10 additions is introduced. The proposed algorithm was assessed in image and video compre…
