Vítor Godeiro

I am MSc. student in Computer Science at Institute of Informatics in the Federal University at Rio Grande do Sul, working under the supervision of prof. Manuel de Oliveira.

I did my bachelor's degrees in Computer Science from Federal University at Rio Grande do Norte, where I was advised by Profs. Bruno Motta de Carvalho and Bruno Santana da Silva.

I'm interested in geometry processing, computer graphics, computer vision, machine learning, image processing, computational photography and human-computer interaction.

Deep Learning-Based Pore Segmentation of Thin Rock Sections for Aquifer Characterization Using Color Space Reduction
Vítor G. Marques, Luis R. D. da Silva, Bruno M. de Carvalho, Leandson R. F. de Lucena, Marcela M. Vieira
IWSSIP, 2019

We proposed a method for segmenting and classifying thin rock sections into pores and background (comprised of rocks and cement), by using a procedure that performs color space reduction on the CIELab space and pixel classification using convolutional networks.

Chronic Wound Tissue Classification using Convolutional Networks and Color Space Reduction

MLSP, 2018

We proposed a method for segmenting and classifying chronic ulcers into three types of tissues. Our method consists of a step for reducing the noise, followed by the watershed based segmentation of the ulcer, color space reduction on the CIELab space and tissue classification using the U-Net.


Raw Image Decoder
Vítor Godeiro, 2019

This project is a raw image decoder implemented in Python. This code convert the raw image into full color image. In this pipeline we read file in pattern [R G G B] and perform the bilinear demosaic then we can choose the white balance algorithm between Gray World, White Patch, Iterative and Percentile. Finally the code run the gamma correction and give the result image.


Vector Graphics Rendering
Vítor Godeiro, 2018

Vector Graphics Rendering developed in LUA at 2D Computer Graphics summer course at IMPA. This render is able to draw quadratic and cubic Bézier curves, transparency, linear and radial gradients, supersampling and acceleration datastructures.


Driver Drowsiness Detection
Vítor Godeiro, 2017

This is a project implementing Computer Vision techniques to detect drowsiness of a driver and emit sound and luminous alert. This code can detect your eyes, mouth, head tilt and alert when the user is drowsy or sleeping.


Vítor Godeiro, Leno Pereira, 2015

This is a game of maze. The maze generation is randomizes using disjoint sets, the exit path is found by backtracking. In this game it is possible to play against an artificial intelligence, the difficulty of artificial intelligence is based on the coefficient of intelligence, which influences the time to make a decision, the ability to make the right decision and the remembrance of the already exploited cells.


Vítor Godeiro, 2015

Flood It is a simple strategy game in which you have to flood the whole game board with one color in less than the permitted steps. The project was developed in C++ using the Simple and Fast Multimedia Library (SFML).


Vítor Godeiro, Samuel Natã, 2015

This project implement the GPU in FPGA Altera DE0 Board. The GPU should use a framebuffer with resolution capability 90x90 pixels. The project draws Lines and Circles.
