Eyelid margin is one of the most challenging anatomic regions in human body and eyelid tumors raise special difficulties field periocular surgery based on anatomical, histological aesthetic points view.

A Biometric system is an automatic identification of an individual based on a unique feature or characteristic. Iris recognition has great advantage such as variability, stability and security. In this paper, use the two methods for iris segmentation -An automatic segmentation method and Window method. Window method is a novel approach which comprises two steps first finds pupils' center and th...

this paper demonstrates design and fabrication o f a mechatronic system for human drowsiness detection. this system can be used in multiple places. for example, in factories, it is used on some dangerous machinery and in cars in order t o prevent the operator o r driver from falling asleep. this system is composed of three parts: (1) mechanical, (2) electrical and (3) image processing system. a...

purpose: to describe a patient with eyelid sarcoidosis. case report: a 54 year-old patient was referred for an eyelid mass from 6 months ago.excisional biopsy showed inflammatory granuloma with tuton gaint cells. chest radiograph demonstrated bilateral hilar adenopathy, increased absorption on gallium scan was noted and bronchoalveolar lavage confirmed a diagnosis of sarcoidosis. treatment with...

Eye detection and eye state (close/open) estimation are important for a wide range of applications, including iris recognition, visual interaction and driver fatigue detection. Current work typically performs eye detection first, followed by eye state estimation by a separate classifier. Such an approach fails to capture the interactions between eye location and its state. In this paper, we pro...

PURPOSE A youthful female upper eyelid contour includes a concave medial portion of the upper eyelid along with a fuller, convex lateral eyelid. The skin in the lateral eyelid is tight without hooding. This is a sigmoid shape in 3-dimensional terms. With aging, fatty herniation medially along with redundant, hooded, ptotic lateral skin creates the exact opposite eyelid curve. The sigmoid blepha...

in this study ten pairs of superior gland of third eyelid of 10 adult male camels free of apparent ocular disease were examined to compare the normal anatomical and histological properties of these glands. after dissecting, all of the glands were characterized and measured (length and width) on both the left and right side. in the camels, the superior gland of the third eyelid was oval shaped a...
