Automatic Object Recognition Algorithm
Automatic object recognition is a highly challenging task in computer vision. These challenges can be caused by many factors reducing the recognition rate of a given algorithm, such as image blur, non-standard viewing angle of the object, partial occlusion and illumination, to list only a few. Di...

Biomedical image processing (or more precisely, biomedical image and signal processing) consists in sophisticated analytical methods and algorithms, ubiquitously found integrated into diagnostic equipment and clinical imaging modalities. The contribution of biomedical image processing and compute...

Eyeglasses have been with us since the 13th century, although mass production and affordability to commoner (aside from clerics, scholars and wealthy people) has begun around the onset of the industrial revolution. Once symbolizing old age and degradation, eyeglasses have integrated our life and ...
Read MoreVideo tracking of animal behavior
Animals display a diverse set of behavior, not always well interpreted by humans: some of these behavioral patterns disclose animals’ intensions, needs, and distresses. Thousands of years of animal farming have enabled us to interpret a subset of animal behavior; yet, a large spectrum still remai...
Read MoreThree-dimensional reconstruction
Three-dimensional reconstruction of scene can be viewed as is the reproduction of a depth-map. Thus, as an input we have a sequence of images as input, which their output is distances of each point of the target object from a reference point. There are many ways to reconstruct an object. Starting...

Heart failure is the leading cause of mortality in the western world. Routine examination in clinics can greatly reduce the risk of heart failure by recognizing early symptoms, correcting classification and assigning appropriate treatment. Monitoring the heart during a clinic visit can shed light...

One ml of human blood contains roughly 5 million red blood cells. This huge quantity is only a fraction of what is found in one ml of blood, which contains roughly 60% fluid (plasma) and the remaining white cells, red blood cells and platelets. The composition of blood is examined routinely in ho...
Read MoreDegenerative Diseases Detection in the Eye
Modern imaging knows how to capture an image to see through the eye tissue transparency and inspect retina, vasculature and neural tissue: this phenomenon is unique and it is made possible by the fact that the retina is an extension of the central nervous system (CNS), connected with the optic ne...
Read MoreImage processing for pediatric strabismus
Strabismus is a disorder in which the eyes are not properly aligned and point to different directions. When this happens, the “straighter” eye becomes more dominant and the weaker eye does not focus properly. Eventually, the brain ignores input from the weaker eye; this disorder is called amblyop...
Read MoreROP: Retinopathy of Prematurity
Retinopathy of prematurity (ROP) is a leading cause of blindness in infants. ROP (or Terry syndrome) is a disease of the eye affecting prematurely-born, low birthweight infants having received intensive neonatal care which includes oxygen therapy. Oxygen toxicity causes abnormal growth of retinal...
Read MoreObject tracking in videos
Object tracking in videos is a classical computer vision problem. It consists of not only detecting the object in a scene but also recognizing the object in each and every frame, so as to distinguish it from other objects, both static and dynamic. Many tracking algorithms have been proposed in th...
Read MoreEyelid Drooping – Blepharoptosis
Blepharoptosis, also known as ptosis, is a drooping of the upper eyelid causing a narrowing of the palpebral fissure (or palpebral aperture), which is the opening between the eye lids. Eyelid drooping may result from any affection of the nerve supply of the upper eyelid musculature, from a diseas...
Read MoreValidation of accuracy in navigation systems
System validation of accuracy is an offline procedure performed periodically to confirm that the tracking system is accurate. In some cases, validation of accuracy can be performed as an ASTM (American Society for Testing and Materials) testing procedure. The testing involves a standard jig assem...

Registration is a phase of orthopedic surgeries in which a visualization system is called to support the surgeon. This system provides real time view of the surgery environment and the information from the CT imaging. Two different steps of registration are executed here: tracking system registra...

CT image segmentation is a typical phase of orthopedic surgeries in which a visualization system is called to visually support the surgeon’s task. This system provides a real time view of the surgery environment, as well as information coming from the pre-op planning and from the CT. It enables h...
Read MoreCalibration of X-ray images
Background During the last 10 years, advanced applications have been using X-rays in the operation room together with other components, like navigation systems or CT over X-ray visualization systems, to support the surgeon in some of his or her tasks. C-arm images, like many camera images, suffer...

Cardiovascular disease is the leading cause of mortality worldwide, accounting for 30% of all deaths and about 17 million premature deaths annually. However, these figures are decreasing due to increased awareness, healthier lifestyle and cardiac examinations which can prevent deterioration and ...
