Public Presentations

Several public presentations have been done in the last years. Some of them are as a keynote speaker or speaker in international conferences in English… other ones as a local speaker at the University in Spanish. Here you can find the most important presentations. See more

X-ray detection in 3D

Supplementary material for the paper: Riffo, V.; Godoy, I.; and Mery, D. (2019): Handgun Detection in Mono-energetic Multiple X-ray Views Based on 3D Object Recognition, Journal of Nondestructive Evaluation. 2019 See code and images.

Face-R

This is the database and the code for the Automated Student System that we presented at WACV 2019. The database contains full-annotaed 25 sessions of a classroom with around 70 students. The session images were taken in 15 week during a semester at the School of Engineering at the Catholic University of Chile.

GDXray database

As a service to the X-ray testing and Computer Vision communities, we collected more than 19.400 X-ray images for the development, testing, and evaluation of image analysis and computer vision algorithms. The X-ray images included in GDXray can be used free of charge, for research and educational purposes only. Redistribution and commercial use are prohibited. See more…

ASR+

This is the supplementary material for our algorithm ‘Adaptive Sparse Recognition with Random Patches for Recognition of Facial Attributes and Face Recognition’.

> Code, datasets and examples: See GitHub repository.

ASR+ used in recognition of facial attributes was presented at ECCV2014 Workshop on Soft-Biometrics (see slides and paper –best paper award). ASR+ used in face recognition will be presented at WIFS2014 (see paper). 

AISM

This is the suplementary material of our algorithm ‘Adapted Implicit Shape Model’ used to detect threat objects in baggage screening. Download Matlab code and imagesexample and paper:

Xdefects (Xray-Testing)

This is the suplmentary material of the paper presented at WACV-2017 that evaluates 24 different computer vision algorithms on a dataset of 47.520 cropped images that contains defects and no-defects in aluminum castings.

AR-LQ (Low-quality AR face images)

We release a new dataset called AR-LQ that can be used in conjunction with the well-known AR dataset to evaluate face recognition algorithms on blurred and low-resolution face images. The dataset contains five new blurred faces (at five different levels, from low to severe blurriness) and five new low-resolution images (at five different levels, from 66×48 to 7×5 pixels) for each of the hundred subjects of the AR dataset. Download dataset ARLQ.

ALSR

This is the suplmentary material of the paper presented at ICASSP-2018. ALSR can be used for face recognition and recognition of facial attributes. In these examples, ALSR is used for face recognition (using LFW dataset), gender recognition (using AR dataset) and expression recognition (using Oulu-CASIA dataset).
