Meibomian gland dysfunction detection

By R. A. / 22/01/2017 / RSIP Vision Learns / No Comments

Meibomian gland dysfunction is often seen as an early stage of dry eye syndrome. Indeed, Meibomian glands play a significant role in tears production by contributing lipids to the superficial tear film. Pathologies which occur in meibomian glands limit the secretion of oil, causing poor lubricati...

Geographic Atrophy (GA)

By R. A. / 24/11/2016 / RSIP Vision Learns / No Comments

Geographic Atrophy (generally called GA) is a case of advanced Dry AMD (Age-related Macular Degeneration) which might lead to vision loss. As a consequence of the thinning of the retina and loss of RPE layer (Retinal Pigment Epithelium, located just outside the retina) via death of rods and cones...

Segmentation and tracking of kidney stones

By R. A. / 07/08/2016 / RSIP Vision Learns / No Comments

An affected anatomical region can be treated in a selective and non-invasive manner by localized and contact-free methods such as high-intensity focused ultrasound. Treatment by selective use of focused beams offers higher patients benefit than non-selective therapy since they spare the healthy t...

Lesion segmentation by random-forest classifiers

By R. A. / 19/07/2016 / RSIP Vision Learns / No Comments

Segmentation of lesions in images, such as those obtained from MRI, ultrasound, CT etc, can be viewed as classifying pixels (or voxels, in the 3-D case) of the image into one or more classes. In the general case, several classes are used, indicating the membership, or probability of each pixel to...

Detection and quantification of bone cancer

By R. A. / 05/05/2016 / RSIP Vision Learns / No Comments

Primary malignant tumor of the bone (osteosarcoma) is the most common bone tumor, representing 88% of all bone tumors with nearly 3,000 annual diagnosed cases in the United States. Despite the relative low occurrence of primary osteosarcoma (less than 1% of all tumors), secondary (metastatic) bon...

Bones and Skeleton segmentation

By R. A. / 04/02/2016 / RSIP Vision Learns / No Comments

Computed tomography (CT) is the most common 3D process used for bone imaging. This is due to the fact that simple thresholding is usually sufficient to identify the bone tissue, based on its higher attenuation of X-rays as compared to soft tissues. The representation of a tridimensional model out...
