About us

Welcome to the Biomedical Image Processing group

Bringing Intelligence to Pixels

 

Founded in 2011 by professor Ricardo J. Ferrari, Ph.D. with the goal of developing practical solutions to significant problems in the biomedical field, the BIPGroup has its focus on Image and Video Processing, Computer Vision, and Machine Learning (including applications of Artificial Intelligence (AI) technology, such as CNNs, Autoencoders and Transformers) techniques for automatically assessing and interpreting biomedical images.

​

Current research projects aim to segmenting, classifying and analyzing 3D magnetic resonance (MR) brain images for neurodegenerative diseases' studies, such as Alzheimer's, Vascular Dementia and Multiple Sclerosis, among others biomedical imaging issues.

​​

Our group is composed of innovative, talented and committed under and graduate students and, despite being relatively small, it is vibrant and very focused. 

​​

If you would like to know more about our research projects or to be a part of our group, please contact us or look at our recent publication works. We are always looking for very interested and committed students to join our team.
​
Companies interested in consulting services or collaboration in research projects may also contact Prof. Dr. Ricardo J. Ferrari.
