A reusable pipeline for large-scale fiber segmentation on unidirectional fiber beds using fully convolutional neural networks
Alexandre Fioravante de Siqueira, Daniela Mayumi Ushizima, Stéfan van der Walt
Fiber-reinforced ceramic-matrix composites are advanced materials resistant to high temperatures, with application to aerospace engineering. Their analysis depends on the detection…
Segmentation of scanning electron microscopy images from natural rubber samples with gold nanoparticles using starlet wavelets
Alexandre Fioravante de Siqueira, Flávio Camargo Cabrera, Aylton Pagamisse +1
Electronic microscopy has been used for morphology evaluation of different materials structures. However, microscopy results may be affected by several factors. Image processing me…
Jansen-MIDAS: a multi-level photomicrograph segmentation software based on isotropic undecimated wavelets
Alexandre Fioravante de Siqueira, Flávio Camargo Cabrera, Wagner Massayuki Nakasuga +2
Image segmentation, the process of separating the elements within an image, is frequently used for obtaining information from photomicrographs. However, segmentation methods should…
An automatic method for segmentation of fission tracks in epidote crystal photomicrographs
Alexandre Fioravante de Siqueira, Wagner Massayuki Nakasuga, Aylton Pagamisse +2
Manual identification of fission tracks has practical problems, such as variation due to observer-observation efficiency. An automatic processing method that could identify fission…
