New method for digitization and manipulation of textile molds based on image processing
(Proceedings of SPIE - The International Society for Optical Engineering, 2022)
A New Family of Distance Functions for Perceptual Similarity Retrieval of Medical Images
(SPRINGER, 2009)
A long-standing challenge of content-based image retrieval (CBIR) systems is the definition of a suitable distance function to measure the similarity between images in an application context which complies with the human ...
JSEG-based image segmentation in computer vision for agricultural mobile robot navigation
(2009-12-01)
This project aims to apply image processing techniques in computer vision featuring an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization ...

Improving synthetic aperture image by image compounding in beamforming process
(2011-11-10)
In this work, signal processing techniques are used to improve the quality of image based on multi-element synthetic aperture techniques. Using several apodization functions to obtain different side lobes distribution, a ...
Estimation of C2n based on scintillation of fixed targets imaged through atmospheric turbulence
(Optical Society Of America, 2015-12)
We define a pixel-based scintillation index for dynamic incoherent imaging of fixed high-contrast targets through atmospheric turbulence. We propose a simple setup to study this parameter varying the C2n constant in ...
Using a Markov Random Field for Image Re-ranking Based on Visual and Textual Features
(Revista Computación y Sistemas; Vol. 14 No. 4, 2011-06-06)
Abstract. We propose a novel method to re-order the list of images returned by an image retrieval system (IRS). The method combines the original order obtained by the IRS, the similarity between images obtained with visual ...
Efficient parallelization on GPU of an image smoothing method based on a variational model
(2016-07-21)
Medical imaging is fundamental for improvements in diagnostic accuracy. However, noise frequently corrupts the images acquired, and this can lead to erroneous diagnoses. Fortunately, image preprocessing algorithms can ...
Baseline-free Damage Imaging Algorithm using Spatial Frequency Domain Virtual Time Reversal
(2021-01-01)
Structural health monitoring techniques are widely used in industry applications to guarantee the integrity of several types of components. This article proposes a baseline-free damage imaging algorithm based on Spatial ...
