BACKGROUND The immunopathogenesis of tuberculosis-associated immune reconstitution inflammatory syndrome (IRIS) remains incompletely understood, and we know of only 1 disease site-specific study of the underlying immunology; we recently showed that Mycobacterium tuberculosis culture positivity and increased neutrophils in the cerebrospinal fluid (CSF) of patients with tuberculous meningitis (TB...

Abstract Traditional iris recognition has high accuracy and low misrecognition rate. However, in the case of mobile terminal or distance, image resolution quality decrease, rate also decreases. To solve above problems, this article is based on deep learning technology, basis single mode state recognition, from different levels multimodal integration, eyes score level fusion research, put forwar...

INTRODUCTION In the recent years, drastic improvements have been accomplished in the areas like iris recognition, automated iris segmentation, edge detection, boundary detection etc. Iris recognition is a biometric recognition technology that utilizes the pattern recognition techniques based on the high quality images of iris. An iris recognition system mainly uses infrared or else the visible ...

PURPOSE Epithelial cysts of the iris may be primary or secondary. The management of secondary, posttraumatic iris cysts is often challenging. The purpose of this work is to report the successful surgical management of a post-traumatic iris cyst. CASE REPORT A 38 year-old man presented with an iris cyst associated with epithelial downgrowth and total cataract, six years after sustaining a pene...

CS: Cowden syndrome PTEN: phosphatase and tensin homolog INTRODUCTION Iris mammillation is an uncommon congenital anomaly of the eye that is rarely reported in the literature; initial reports describe iris mammillations using different terminology, such as bilateral iris melanosis, dotted Swiss iris, and bilateral diffuse iris nodular nevi. Microscopic examination finds focal nesting of spindle...

Tuberculous meningitis (TBM) is a frequent cause of meningitis in individuals with human immunodeficiency virus (HIV) infection, resulting in death in approximately 40% of affected patients. A severe complication of antiretroviral therapy (ART) in these patients is neurological tuberculosis-immune reconstitution inflammatory syndrome (IRIS), but its underlying cause remains poorly understood. T...

Iris recognition is one of the most reliable and accurate biometric technologies, as the richness and apparent stability of the iris texture make it robust. Iris segmentation is a critical part in iris recognition, because it defines the inner and outer boundaries of iris region which is used for feature analysis. Active contour model, also known as snake, is a powerful image segmentation techn...

In this paper, we evaluate the performance of feature extraction methods for iris pattern classification. Generally, the identification system using iris recognition consists of the iris localization block and the iris pattern classification block. In this paper, we used the 2D bisection-based Hough transform and the radius histogram method for the iris localization and we used multilayer perce...

The TB immune reconstitution inflammatory syndrome (IRIS) is a relatively frequent complication in HIV-TB-coinfected patients after they start highly active antiretroviral therapy (HAART). There are two forms of TB IRIS: the 'paradoxical' type (clinical worsening of a patient on TB treatment) and the 'unmasking' type (undiagnosed TB becoming apparent after starting HAART). Their pathogeneses ar...

De-duplication of biometrics is not scalable when the number of people to be enrolled into the biometric system runs into billions, while creating a unique identity for every person. In this paper, we propose an iris classification based on sparse representation of log-gabor wavelet features using on-line dictionary learning (ODL) for large-scale de-duplication applications. Three different iri...
