A Class of Low-complexity DCT-like Transforms for Image and Video Coding
T. L. T. da Silveira, D. R. Canterle, D. F. G. Coelho +3
The discrete cosine transform (DCT) is a relevant tool in signal processing applications, mainly known for its good decorrelation properties. Current image and video coding standar…
Data-independent Low-complexity KLT Approximations for Image and Video Coding
A. P. Radünz, T. L. T. da Silveira, F. M. Bayer +1
The Karhunen-Loève transform (KLT) is often used for data decorrelation and dimensionality reduction. The KLT is able to optimally retain the signal energy in only few transform co…
Low-complexity 8-point DCT Approximation Based on Angle Similarity for Image and Video Coding
R. S. Oliveira, R. J. Cintra, F. M. Bayer +3
The principal component analysis (PCA) is widely used for data decorrelation and dimensionality reduction. However, the use of PCA may be impractical in real-time applications, or…
