Research on Computer Vision & Pattern Recognition

Connected Components Labeling

Labeling logo

In 2010, research activity on Connected Component Labeling (CCL) algorithms leaded to the development of an open source version of a very fast labeling routine called Block Based with Decision Trees (BBDT). Recently, our research group released YACCLAB (Yet Another Connected Component Labeling Algorithm Benchmark) an open source CCL performance evaluation benchmark which compare the performance of the state of the art labeling algorithms. The benchmarking system confirms the very good performances of the BBDT algorithm which is now the default algorithm included in the OpenCV library. 


Visual Saliency Prediction

When human observers look at an image, attentive mechanisms drive their gazes towards salient regions. Emulating such ability has been studied for more than 80 years by neuroscientists and by computer vision researchers, while only recently, thanks to the large spread of deep learning, saliency prediction models have achieved a considerable improvement.


Motivated by the importance of automatically estimating the human focus of attention on images, we developed two different saliency prediction models which have overcome previous methods by a big margin winning the LSUN Saliency Challenge at CVPR17, Honolulu, Hawaii.


Animal welfare analysis from 3D sensors

Stray dog populations represent a serious concern for human beings health and safety and for dogs themselves in many European countries [1]. The main population control action plan in Italy, but also in other countries, is the confinement of stray dogs in shelter facilities until re-homing. Unfortunately, the impairment between entrance and adoption rates often leads to an overcrowded scenario where dogs are likely to spend most part of their lives. We propose a computer vision system for the evaluation of the behaviour and the well-being of the dogs housed in these shelters.


3D Computer Vision

3D Surface

Three-dimensional object modeling and recognition on range data and 3D point clouds is becoming more important nowadays. We are exploring and studying new solutions and algorithms based on 3D point clouds, ranging from industrial applications to human computer interaction.


3D Reconstruction of Skin Lesions for Tumor Diagnosis in OCT imaging

Logo 3D Vessel Reconstruction

Optical Coherence Tomography (OCT) allows to capture the internal structure of skin lesions. In this project we develop an image analysis pipeline to obtain 3D models from OCT scans. Both the external surface and the internal vascular network are reconstructed to give to the clinicians new qualitative tools for tumor diagnosis.

This project is developed in conjunction with the dermathologists of Policlinico di Modena under the direction of Prof. Giovanni Pellacani.

This research is funded by the European Project ADVANCE: Automatic Detection of VAscular Networks for Cancer Evaluation.
