On the Impact of Entropy-based Features
Iuri Mundstock, Abreu Quevedo, Jéferson Campos Nobre +3
Network anomaly detection is increasingly challenging due to the growing diversity and variability of traffic patterns, which are not always well captured by traditional statistica…
Sorting of Smartphone Components for Recycling Through Convolutional Neural Networks
Álvaro G. Becker, Marcelo P. Cenci, Thiago L. T. da Silveira +1
The recycling of waste electrical and electronic equipment is an essential tool in allowing for a circular economy, presenting the potential for significant environmental and econo…
"A Nova Eletricidade: Aplicações, Riscos e Tendências da IA Moderna -- "The New Electricity": Applications, Risks, and Trends in Current AI
Ana L. C. Bazzan, Anderson R. Tavares, André G. Pereira +7
The thought-provoking analogy between AI and electricity, made by computer scientist and entrepreneur Andrew Ng, summarizes the deep transformation that recent advances in Artifici…
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…
Multiplierless 16-point DCT Approximation for Low-complexity Image and Video Coding
T. L. T. Silveira, R. S. Oliveira, F. M. Bayer +2
An orthogonal 16-point approximate discrete cosine transform (DCT) is introduced. The proposed transform requires neither multiplications nor bit-shifting operations. A fast algori…
An Orthogonal 16-point Approximate DCT for Image and Video Compression
T. L. T. da Silveira, F. M. Bayer, R. J. Cintra +3
A low-complexity orthogonal multiplierless approximation for the 16-point discrete cosine transform (DCT) was introduced. The proposed method was designed to possess a very low com…
