We present a prototype to identify eye states from electroencephalography signals captured one or two channels. The hardware is based on the integration of low-cost components, while signal processing algorithms combine discrete wavelet transform and linear discriminant analysis. consider different parameters: nine wavelets features extraction strategies. A set experiments performed in real sce...

This paper describes algorithms for face and facial features detection in still frontal images. It is designed for the task of automatic image-based 3-D face modelling. This requires the detection to be accurate enough to produce exact facial features and robust to images of widely varying quality and picture taking conditions. The facial feature detection task is solved in several steps. First...

Abstract Background and Aims: Cytomegalovirus (CMV) infection is very common in the population. Virus belongs to the family Herpesviridae, whose representatives are characterized by the ability to cause the human body's latent persistent infections. The goal of the study is to assess the CMVV infection frequency and PCR method in the choice of CMV in inflammatory eye disease, Comparing wit...

Precise eye status detection and localization is a fundamental step for driver distraction detection. The efficiency of any learning-based object detection method highly depends on the training dataset as well as learning parameters. The reported research develops optimum values of Haar-training parameters to create a nested cascade of classifiers for real-time eye status detection. The detecto...

Animal species detection is one of the crucial steps for consumer’s food analysis. In the present study we developed an in-house built loop-mediated isothermal amplification (LAMP) assay for rapid detection of adulterated cow DNA in goat milk/meat samples. The cow milk/tissue DNA in goat milk/meat samples were identified in the developed LAMP assay by either naked eye visualizing with SYBR Gree...

The eyes are important facial landmarks, both for image normalization due to their relatively constant interocular distance, and for post processing due to them anchoring model-based schemes. This paper introduces a novel approach for the eye detection task using optimal wavelet packets for eye representation and Radial Basis Functions (RBFs) for subsequent classification (’labeling’) of facial...

OBJECTIVE To evaluate the ability of the fellow eye to detect stimuli in the area corresponding to the ring scotoma (blind area) of a monocular bioptic telescope in simple conditions (conventional perimetry) and in more visually demanding conditions. METHODS A computerized dichoptic perimeter enabled separate stimuli to be presented to each eye of 7 bioptic users and 7 nonusers. The bioptic r...

The health of the ocular surface requires blinks of the eye to be frequent in order to provide moisture and to renew the tear film. However, blinking frequency has been shown to decrease in certain conditions such as when subjects are conducting tasks with high cognitive and visual demands. These conditions are becoming more common as people work or spend their leisure time in front of video di...
