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 and algorithms
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...

Biometric Detection and Measurement
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 ...

Video 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...

Three-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...

Algorithms for Autonomous Driving
The transportation revolution coming with autonomous cars has already started, involving challenges that require proper handling of advanced technologies and algorithms: deep learning, to name one. . . Autonomous Driving is classified according to 5 Levels, all higher than Level Zero, where no au...

Cardiovascular Ultrasound Software
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...

Cell Classification software
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...

Three-dimensional reconstruction of a deformable object
Reconstruction of the three-dimensional surface of an object based on single view 2-D sequence of images is a highly challenging task. Challenges stem in part from the construction of a template representing the object, or more formally, incorporating knowledge to restrict the shape space. The po...

Degenerative 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...

Image 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...

ROP: 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...

Object 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...

Eyelid 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...

Validation 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...

Navigation System in Orthopedic Surgery
The navigation system is one of the most powerful tools for the surgeon in the new orthopedic surgery procedures. The visualization system aids the surgeon to place his or her tools without excessive exposure to X-ray radiations. The objectives of the Navigation System Present 2D and 3D views of ...

Registration of CT and X-ray
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 Segmentation in orthopedic surgery
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...

Calibration 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...
