While several previous studies have devised methods for segmentation of polyps, most of these methods are not rigorously assessed on multi-center datasets. Variability due to appearance of polyps from one center to another, difference in endoscopic instrument grades, and acquisition quality result in methods with good performance on in-distribution...
Conference Paper
Dans cette contribution nous utilisons une méthode ensembliste d'apprentissage profond pour combiner la prédiction de deux détecteurs individuelsà unétage (c'est-à-dire YOLOv4 et Yolact) dans le but de détecter les artefacts vus dans des images endoscopiques. Cette stratégie ensembliste a permis d'améliorer la robustesse des modèles individuels san...
Chapter
Colorectal cancer cases have been increasing at an alarming rate each year, imposing a healthcare burden worldwide. Multiple efforts have been made to treat this malignancy. However, early screening has been the most promising solution. Optical endoscopy is the primary diagnosis and treatment tool for these malignancies. Even though its success, th...

Prevalence of gastrointestinal (GI) cancer is growing alarmingly every year leading to a substantial increase in the mortality rate. Endoscopic detection is providing crucial diagnostic support, however, subtle lesions in upper and lower GI are quite hard to detect and cause considerable missed detection. In this work, we leverage deep learning to...

In this contribution we use an ensemble deep-learning method for combining the prediction of two individual one-stage detectors (i.e., YOLOv4 and Yolact) with the aim to detect artefacts in endoscopic images. This ensemble strategy enabled us to improve the robustness of the individual models without harming their real-time computation capabilities...

This work describes the development of a controlled cabin for capturing and analyzing thermal images. The motivation of such a device is to aid in the thermal image acquisition process within a confined space. The thermograms generated provide helpful information for analyzing the residual human limb in subjects with transtibial amputation. Such a...

Human language is the main channel humans use to communicate between each other, however, it is also very complex, ambiguous, and highly variable. The performance of novel natural language processing algorithms have caught the attention of the research community. This article presents a natural language processing approach for solving the task of d...

Science and technology in Mexico have always been a topic to discuss in recent years, as it is usually seen as a trivial topic in which Mexicans are not commonly attracted to participate. The Mexican government dedicates funds to this situation, but the rulers who have had recently have been affecting it and investment has decreased. Research canno...
