Hyperspherical embedding for novel class classification
Rafael S. Pereira, Alexis Joly, Patrick Valduriez +1
Deep learning models have become increasingly useful in many different industries. On the domain of image classification, convolutional neural networks proved the ability to learn…
Applying Lie Groups Approaches for Rigid Registration of Point Clouds
Liliane Rodrigues de Almeida, Gilson A. Giraldi, Marcelo Bernardes Vieira
In the last decades, some literature appeared using the Lie groups theory to solve problems in computer vision. On the other hand, Lie algebraic representations of the transformati…
Towards a glaucoma risk index based on simulated hemodynamics from fundus images
José Ignacio Orlando, João Barbosa Breda, Karel van Keer +3
Glaucoma is the leading cause of irreversible but preventable blindness in the world. Its major treatable risk factor is the intra-ocular pressure, although other biomarkers are be…
Fourier Analysis and Holographic Representations of 1D and 2D Signals
G. A. Giraldi, B. F. Moutinho, D. M. L. de Carvalho +1
In this paper, we focus on Fourier analysis and holographic transforms for signal representation. For instance, in the case of image processing, the holographic representation has…
Gradient Vector Flow Models for Boundary Extraction in 2D Images
Gilson A. Giraldi, Leandro S. Marturelli, Paulo S. Rodrigues
The Gradient Vector Flow (GVF) is a vector diffusion approach based on Partial Differential Equations (PDEs). This method has been applied together with snake models for boundary e…
