Application of Enhanced-2D-CWT in Topographic Images for Mapping Landslide Risk Areas
V. V. Vermehren Valenzuela, R. D. Lins, H. M. de Oliveira
There has been lately a number of catastrophic events of landslides and mudslides in the mountainous region of Rio de Janeiro, Brazil. Those were caused by intense rain in localiti…
Converting ECG and other paper legated biomedical maps into digital signals
A. R. Gomes e Silva, H. M. de Oliveira, R. D. Lins
This paper presents a digital signal processing tool developed using MatlabTM, which provides a very low-cost and effective strategy for analog-to-digital conversion of legated pap…
Taylor Series as Wide-sense Biorthogonal Wavelet Decomposition
H. M. de Oliveira, R. D. Lins
Pointwise-supported generalized wavelets are introduced, based on Dirac, doublet and further derivatives of delta. A generalized biorthogonal analysis leads to standard Taylor seri…
