Wavelets behind the scenes: Practical aspects, insights, and perspectives
Guido, Rodrigo Capobianco (Physics Reports, 2022) [Resenha]
Over the years, wavelet-based analyses have been responsible for remarkable achievements in physics and related sciences. Nevertheless, a deep inspection on wavelet-based strategies described in recent scientific papers, ... -
Interpretability, Reproducibility, and Replicability
; Guido, Rodrigo Capobianco; ; ; (IEEE Signal Processing Magazine, 2022) [Editorial]
Most of the work we do in signal processing these days is data driven. The shift from the more traditional and model-driven approaches to those that are data driven has also underlined the importance of explainability of ... -
Empirical mode decomposition applied to acoustic detection of a cicadid pest
; ; ; ; Guido, Rodrigo Capobianco (Computers and Electronics in Agriculture, 2022) [Artigo]
The sounds emitted by various insect species are highly specific and, thus, can be used as a way to acoustically characterize them. Consequently, acoustic insect detection has been widely studied by the scientific community ... -
Multidimensional shannon entropy (HM) as an approach to classify H&E colorectal images
Santos, Luiz Fernando Segato Dos; Rozendo, Guilherme Botazzo ; ; ; Longo, Leonardo Henrique Da Costa ; Neves, Leandro Alves (International Conference on Systems, Signals, and Image Processing, 2022) [Trabalho apresentado em evento]

Percolation Features: An approach for evaluating fractal properties in colour images[Formula presented]
; Neves, Leandro Alves; da Costa Longo, Leonardo Henrique ; Rozendo, Guilherme Botazzo ; ; ; ; (Software Impacts, 2022) [Artigo]
Percolation is a physical phenomenon that describes the transport of fluids through porous media. We present a new approach for extracting local and global percolation features from RGB images. The proposed method is based ... -
Studies about Snake Peptides: A Review about Brazilian Contribution
Assis, Rhayane Alves; ; ; ; ; ; (Brazilian Archives of Biology and Technology, 2022) [Artigo]
The peptides present in snake venoms are studied because of their properties, constitutions, mechanisms of action and pharmacological potential. Recognizing this potential, the present study reports the contributions of ... -
Apriori-roaring: frequent pattern mining method based on compressed bitmaps
Colombo, Alexandre; Spolon, Roberta ; Junior, Aleardo Manacero ; Lobato, Renata Spolon ; (International Journal of Business Intelligence and Data Mining, 2022) [Artigo]
Association rule mining is one of the most common tasks in data analysis. It has a descriptive feature used to discover patterns in sets of data. Most existing approaches to data analysis have a constraint related to ... -
Sample Entropy Signatures: A new way to interpret SampEn values[Formula presented]
Rozendo, Guilherme Botazzo; ; ; ; ; ; Neves, Leandro Alves (Software Impacts, 2022) [Artigo]
We present the Sample Entropy Signatures method, which provides a new way to represent images via Sample entropy (SampEn). The proposed method defines texture signatures from multiple SampEn values obtained from combinations ... -
Classification of non-Hodgkin lymphomas based on sample entropy signatures[Formula presented]
Rozendo, Guilherme Botazzo; ; ; ; ; ; Neves, Leandro Alves (Expert Systems with Applications, 2022) [Resenha]
Computational systems to provide studies and diagnoses of non-Hodgkin's lymphomas have been increasingly developed to assist specialists in their decision-making. On the other hand, the approaches have not yet fully explored ... -
Early Identification of Abused Domains in TLD through Passive DNS Applying Machine Learning Techniques
Silva, Leandro Marcos da; Silveira, Marcos Rogério ; Cansian, Adriano Mauro ; (International Journal of Communication Networks and Information Security, 2022) [Artigo]
