Automatic Object Recognition Algorithm

By R. A. / 13/11/2017 / RSIP Vision Learns / No Comments

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...

Video tracking of animal behavior

By R. A. / 15/08/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 13/08/2017 / RSIP Vision Learns / No Comments

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...

Cell Classification software

By R. A. / 13/06/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 05/06/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 27/03/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 12/03/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 08/03/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 06/03/2017 / RSIP Vision Learns / No Comments

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

By R. A. / 05/03/2017 / RSIP Vision Learns / No Comments

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...
