Lung Segmentation Software
The lower respiratory tract in humans includes the lungs along with their pulmonary vasculature. High degree of capillary and pulmonary branching in the respiratory system provides humans with a surface area of about 70 squared meters, in which an exchange of oxygen and CO2 are continuously being...

Retinal inner layers segmentation
OCT is the only method that can perform noninvasive imaging with non-ionizing radiation and offering relatively good resolution. That is why it has become a standard in clinical ophthalmology. Segmentation of anatomical and pathological structures in ophthalmic images is crucial for the diagnosis...

Statistical pattern discovery in big data
The explosion of data collection techniques and resources is a known phenomenon of the current day and age. Human analysis of such large datasets is largely infeasible and the vast amount of information can only be dealt systematically and efficiently by algorithmic means. The so called ‘big data...

Diabetic retinopathy screening and microaneurysm detection
Diabetic Retinopathy (DR) is a leading cause of blindness, especially among adults and even more among the elderly segments of the population. It is associated with type 1 and type 2 diabetes. It occurs when high glucose levels in the blood damage blood vessels in the retinal area, leading to sma...

Retinal images taken with mobile cameras
Portable cameras able to help ophthalmologists have been a desired solution for a long time. Among the reasons for the need of an additional device to support the eye physician, on top of available fixed devices, is the fact that sometimes patients who need the visit of a doctor live in remote a...

Geographic Atrophy Segmentation Using SD-OCT
In a previous article, we talked about Geographic Atrophy segmentation in 2D images. This article focuses on how OCT images shed light on the development of Geographic Atrophy (GA) pathology. This spectral-domain optical coherence tomography (SD-OCT) modality with its 3D information enables a bet...

Geographic Atrophy (GA)
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...

People counting with infrared camera
The FLIR Lepton is a low-resolution LongWave InfraRed (LWIR) camera. The purpose of this article is to explain the main challenges presented by the use of this IR camera in a typical image processing task like automated people counting. Other imaging tasks may present similar or different challen...

Lanes Detection System
One of the theoretically simplest applications in automatic driving technologies is traffic lanes detection: however, due to the need of a very robust solution to insure the safety of travelers under any road, weather and light condition, even a simple application presents challenges which need t...

Machine fault detection and classification
Automatic detection and diagnosis of various types of machine failure is a very interesting precess in industrial applications. With the advancement of sensors and machine intelligence, the reliability of automatic product inspection and fault detection is ever increasing. Monitoring the health o...

Retina Montage Software
The Need for Retina Montage: Retinal imaging is one of the oldest and most reliable techniques to examine the retina to analyse its status and possibly detect existing disorders. The principle is very simple: a regular camera with proper optics and enough light can look through the pupil and see ...

Deformable pattern matching and classification
Three sources of apparent object deformation can occur: a change in the shape of the object itself, partial or full occlusion by dynamically changing background (other moving object or imaging conditions), or camera motion. Deforming objects are in general hard to track, owing to their unpredicta...

Cataract surgery software
A cataract is a blurring of the eye’s natural lens. This lens lies behind the iris and the pupil of the patient’s eye. Cataract surgery is the procedure by which the cloudy lens is removed and replaced with a new IOL (intraocular lens). This new lens is an artificial medical device, which i...

Optical Coherence Tomography Angiography
Optical coherence tomography angiography (OCTA) is a method which uses OCT to produce high-resolution volumetric images of the vascular tree in the eye. It has the advantage of being a non-invasive procedure. It is quick, and produces high resolution 3-dimensional histological images. With OCTA a...

Automatic Pupil Distance Measurement
Automatically Measuring Pupil Distance For the manufacturing and prescription of modern eye glasses there is a need for high precision measurements. The measured morphological features of the patient’s face and eyes are correlated with physical features of the glasses to ensure the best fit. One ...

Multi-modal registration of retina images
Multi-modal registration of retina images is a process by which pictures taken with different modalities and/or at different times are registered. This is done principally when tracking some kind of condition concerning the patient, e.g. the evolution of a disease. One of the things that ophthalm...

3D object reconstruction by fringe projection
Fringe pattern projection for 3D object reconstruction has been around for 3 decades. The method finds its application in reconstructing static and dynamic objects in diverse fields such as biomedical, dentistry, circuit board inspection, virtual reality, vibration analysis, recreational 3D light...

Stabilization in fluorescein angiography
One of the most common tests in ophthalmology is fluorescein angiography: fluorescein is injected in the blood and it moves immediately through the blood vessels to the back of the eye. Some drops might also be applied in order to make the pupil dilate. A video clip taken shortly after that, show...

Breakthroughs in biomedical imaging
During the last few decades, the field of biomedical imaging was shaken by major breakthroughs, which have completely changed the way physicians can observe imaging data. For instance, not long time ago, radiologists received images (taken by CT, MRI or X-Ray) and had to analyze them from scratch...

Type 2 interval fuzzy sets in pattern classification
In search for a pattern in an image, a video or a signal, one has to consider several sources of bias, noise and uncertainties. Such uncertainties are the result of acquisition of natural signals such as outdoors images in non-sterile and poorly lit conditions, possibly containing smear, blurs, a...
