Building Flyweight FLIM-based CNNs with Adaptive Decoding for Object Detection

no code implementations26 Jun 2023 Leonardo de Melo Joao, Azael de Melo e Sousa, Bianca Martins dos Santos, Silvio Jamil Ferzoli Guimaraes, Jancarlo Ferreira Gomes, Ewa Kijak, Alexandre Xavier Falcao

State-of-the-art (SOTA) object detection methods have succeeded in several applications at the price of relying on heavyweight neural networks, which makes them inefficient and inviable for many applications with computational resource constraints.

Iterative Saliency Enhancement using Superpixel Similarity

no code implementations1 Dec 2021 Leonardo de Melo Joao, Alexandre Xavier Falcao

ISESS estimates seeds for superpixel delineation from a given saliency map and defines superpixel queries in the foreground and background.

ITSELF: Iterative Saliency Estimation fLexible Framework

no code implementations30 Jun 2020 Leonardo de Melo Joao, Felipe de Castro Belem, Alexandre Xavier Falcao

We compare ITSELF to two state-of-the-art saliency estimators on five metrics and six datasets, four of which are composed of natural-images, and two of biomedical-images.

Deep Representations for Iris, Face, and Fingerprint Spoofing Detection

no code implementations8 Oct 2014 David Menotti, Giovani Chiachia, Allan Pinto, William Robson Schwartz, Helio Pedrini, Alexandre Xavier Falcao, Anderson Rocha

We assume a very limited knowledge about biometric spoofing at the sensor to derive outstanding spoofing detection systems for iris, face, and fingerprint modalities based on two deep learning approaches.
