Automatic segmentation of latent fingerprints
(2012-12-01)
Latent fingerprints are routinely found at crime scenes due to the inadvertent contact of the criminals' finger tips with various objects. As such, they have been used as crucial evidence for identifying and convicting ...

Time-Frequency Filtering Based on Model Fitting in the Time-Frequency Plane
(Institute of Electrical and Electronics Engineers, 2019-03)
The modulus of time-frequency representations, like the short-time Fourier or wavelet transforms, of a multicomponent signal exhibit ridges from which one usually computes estimations of the instantaneous frequencies of ...
Fully Adaptive Ridge Detection Based on STFT Phase Information
(Institute of Electrical and Electronics Engineers, 2020-04)
This letter deals with the problem of the estimation of the instantaneous frequencies of the modes of multicomponent signals from their linear time-frequency representations. In most approaches, such an estimation consists ...
Antena corneta cônica quad-ridged compacta com dupla polarização
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-06-08)
This work presents the design and development of a compact dual-pol quad-ridge conical horn
antenna. The antenna is feeded through an innovative feeding system, based on striplines implemented in a Flexible Printed Circuit ...
Fingerprint image enhancement and reconstruction using the orientation and phase reconstruction
Fingerprints are the one of the most important means in the forensics as a means of identification of the criminals owning to the uniqueness and the distinct features in them. Fingerprint identification is considered as ...
Antarctic beaked whale echolocation signals near South Scotia Ridge
(Wiley Blackwell Publishing, Inc, 2015-07)
Several species of beaked whales inhabit the Southern Ocean, but information on their abundance, distribution, and seasonality is scarce. However, beaked whales are the only cetaceans known to use frequency modulated (FM) ...
