Bio-Medical Imaging

within the activities of the CDS-group (formerly ), ICAR-CNR


The activity concerns the analysis, design, and implementation of machine learning methods for multimedia applications involving bio-medical images and image sequences.

Main achievements

Dermoscopic images
Approach to the characterization of uncertain lesions, to detect characteristic profiles of benign and malignant lesions [2]. Based on suitable multi-value descriptors (scalar, interval, and histogram data) extracted by dermoscopic images, it consists in selecting through discriminant analysis the most discriminating features and detecting through dynamic clustering the characteristic profiles.
For the automatic segmentation of skin lesions in dermoscopic images, we proposed the SDI algorithm [6] and the SDI+ algorithm [8], extensively tested on the lesion segmentation dataset made available for the ISIC 2017 challenge on Skin Lesion Analysis Towards Melanoma Detection.

ESC images
Segmentation and classification of microscopy images aimed at identifying specific factors that control the differentiation of Embryonic Stem Cells via large-scale screenings [3][5][7].

HeLa cell image sequences
Segmentation, tracking, and lineage of HeLa cells from phase contrast microscopy time-lapse data [4].

Microarray image
Automatic approach to gridding (also known as addressing or spot finding) in microarray images, based on the Orientation Matching and the Discrete Fourier Transforms [1].
