Pattern Recognition for Lens Markings Detection
Lens marking refers to the placement of temporary and/or permanent marking, semi-visible laser engraving for the use of lens identification and trademarks, and accurate placement of guiding lines along which lenses are cut. In the process of lens manufacturing, accurate placement and localization...

Visual Inspection of Semiconductors
Imprinting information on a silicon wafer is a complex multi-process task. In the wafer fabrication process, nanoimprinting process miniature patterns a coined on the wafer body using a variety of techniques (such as UV and thermal imprints). Defects can occur during the imprinting process, stemm...

OCR Software for Low Contrast Images
Vision technologies harnessed to Intelligent Transportation Systems (ITS) enable detection of vehicles on the road according to their number plate, transmitting traffic flow analysis in real time and tracking individual cars. Automatic identification of cars based on their number plate serves pur...

Meibomian gland dysfunction detection
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...

Glaucoma Detection
Glaucoma is the second cause of blindness in the world, with over 60 million people suffering from the disease. This figure is steadily growing and most people suffering from glaucoma, even in developed countries, are not aware of their condition. Older people are at a higher risk, but glaucoma c...

Retinal Detachment Detection
Retinal detachment occurs when part of the retina detaches itself from the pigmented cell layer of the RPE, depriving itself of blood and nutrition: this condition causes blur and loss of vision. There are 2 types of detachment: either it is caused by fluids, which might be of lacrimal origins, g...

Density Measurement of Damaged Cartilage
Knee cartilage acts as a shock absorber, useful to absorb and damp shock impulses between the thigh (femur) and the shin (tibia) bones. The cartilage layer is a flexible tissue, which serves to ease the pressure put on the knee joint caused by mere walking and the weight of the body it has to car...

Coronary CT Angiography with Deep Learning
Coronary artery pathologies are a leading cause of heart failure and death in the western world. Narrowing and hardening of the vessels carrying oxygen-rich blood to the heart, due to the accumulation of plaque on the vascular walls, is a major source of atherosclerosis, a major cardiovascular di...

Automated diagnostic reading of HIV
Human Immunodeficiency Virus is a double-strand RNA retrovirus, which translates into a DNA by reverse transcription in the cell cytoplasm and later integrated into the genome within the nucleus. The integrated viral DNA harbors genes which remains at most dormant until an initiation of the immun...

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...
