Combining Clinical, Non-clinical and Visual Informations to Build an Artificial Intelligent Agent for Fall Prevention and Dialogs with Patient

The present work proposes a methodology to combine clinical, non-clinical and visual information to build an intelligent assistant to interact and care for patients with fall risk. This work utilizes the most advanced techniques of Natural Language Processing (NLP) to generate dialogs with the patient and Data Science techniques combined with Pose Estimation Algorithms (Computer Vision) to estimate patient's fall risk.

3D Reconstruction of Cranial Medical Images Based on Bio-inspired Algorithms and Deep Learning

The present work proposes a method for the visualization of 3D models of the skull labeled with cephalometric fiducial points. This approach consists of the use of convolutional neural networks for the automatic identification of cephalometric fiducial points, as well as the use of bio-inspired algorithms in the segmentation of Computed Tomography (CT) images for the reconstruction of the three-dimensional model.

A Model for Abstractive Summarization of Scientific Papers Methodology

This project aims to present a methodology based on machine learning techniques for abstractive summarization of the methodology of scientific articles.

Alignment of 3D Medical models on Microsoft Hololens

This research project aims to perform the alignment of 3D models visualized with Microsoft Hololens with real images on which the models are being projected, using methods of fiducial point detection such as SIFT and Convolutional Neural Networks (CNN).

q-GABOR: A proposal of non-extensive version for gabor functions

Gabor functions are an important mechanism to model several types of physical phenomenon. This project proposes for the first time the non-extensive version, named here as q-Gabor, of such functions formalizing them in the spatial domain and demonstrates their usability in digital image processing and computer vision applications.

Automatic Reconstruction of 3D Objects in Indoor Environments with Microsoft Hololens

This project aims to propose modern methods, based on algorithms such as SIFT-CNN, for automatic modeling of volumetric objects with projection of textures on the mesh produced by Microsoft Hololens.

Automatic approach for fake news detection in social networks and we portals

In this paper, we propose a statistical model in order to calculate the percentage of a text to not contain fake content.

BIP - Bioforensic Image Processing

In this paper we approach the copy-move attack, where part of the image is copied into another zone to duplicated or hide some information, and such forgery requires geometric manipulations or other changes that make even harder to detect something only looking at it.

A State of Art Methodology To Point Border Detection in 3D Indoor Meshes

Our work proposes the detection of border points in 3D mesh objects recon- structed from internal environments.

Virtual Assistant for Activity Detection in a Smart Store

The goal of the project is to develop a system to be used in a smart shop that allows a person to enter, pick up the items they want to buy and leave.

AR-Nutri: Machine Learning for Disease Classification, Diet Suggestion for Illness Treatment and Food Recognition with Augmented Reality

This work proposes a platform to i) predict patients’ illness; ii) suggest a diet routine to treat the detected disease; iii) and identify various types of food, in a virtual marketplace.

Object Recognition Based on a Neuro-Cognitive Architecture

In this work, an approach is proposed using cognitive architectures based on the structure of previously established cognitive models, in search of an even greater improvement in their results, adding a dynamics that simulates the human mind.

3D Reconstruction of medical images

The present work aims to propose a methodology for 3D reconstruction of surfaces of unstructured scenes, using AI and computational vision techniques that have been gaining space in the market and in research centers.

Combining Bag of Features and LIDA for Scene Classification

Comparing Recent Optimization Algorithms for Applications in Image Segmentation

The objective of this work is to compare traditional optimization techniques with the most recent methods and to determinate which are the most suitable optimization to be used in the segmentation of images by Thresholding.

Assessing Recommender Systems Algorithms in a Health Scenario to Support Clinical Decisions in Treatment Planning

This work aims at assessing and comparing the most relevant traditional recommender systems algorithms in a treatment procedures recommendation scenario, using real data provided by a public hospital in São Paulo, Brazil.

Body language classification of patients in bed using deep learning

When humans communicate, part of the information is transmitted non-verbally through gestures, facial expressions or body pose. If we analyze this interaction within the scope of health research, specifically between the interactions of hospital staff and patients, this type of information becomes more important due to the fact that an early detection of anomalous behaviors in patients can be fundamental to avoid the worsening of some diseases.

Navigation in unstructured dynamic environments applied to minimally invasive surgeries

The present work aims to propose an image based navigation system to aid physicians in minimally invasive surgeries.
