Glaucoma is the leading causes of blindness, affecting an estimated 70 million individuals in the world. Because an elevated intraocular pressure (IOP) has been identified as a major risk factor, current therapies are aimed at lowering eye pressure. Consequently, monitoring of IOP is the most important tool in diagnosis and management of glaucoma. However current pressure measurement approaches have many ...

Segmentation of vascular structures of retina for implementation of Clinical diabetic retinopathy decision making systems is presented in this paper. As retinal vascular structure is with thin blood vessels, prediction accuracy is highly dependent upon the segmentation and preprocessing schemes. Complex GSZ shock filters have been used for noise suppression and edge enhancement. Binarization algorithms are used to achieve the segmentation of vascular structures of the retina. It has been observed that the combination of shock filter and Binarization provides better segmentation results compared to morphological and region growing methods.
By way of extracellular, stimulating electrodes, electronic vision prosthesis aims to render discrete light spots - so-called phosphenes - in the visual field, thereby providing a phosphene image serving as a rudimentary remediation of profound blindness. It is proposed that a digital camera, or some other photosensitive array, captures frames, the frames be analyzed, and phosphenes be actuated accordingly. We present a numerical experiment wherein we observed the phosphene image in response to a set of stimuli for various image analysis schemes. We used the mutual-information function to quantify the efficacy of analysis schemes; the function penalizes a scheme for introducing redundancy to the phosphene image, while accounting for the probability of each stimulus. We demonstrate an effective scheme involving Laplacian of Gaussian (/spl nabla/2G) kernels geometrically transformed in accordance with phosphene layout. Further, we propose adapting the kernels comprising a scheme in accordance with photosensor movement.
Glaucoma is the leading causes of blindness, affecting an estimated 70 million individuals in the world. Because an elevated intraocular pressure (IOP) has been identified as a major risk factor, current therapies are aimed at lowering eye pressure. Consequently, monitoring of IOP is the most important tool in diagnosis and management of glaucoma. However current pressure measurement approaches have many challenges: measurements are obtained at the doctor's office only every few months, and it is difficult to develop more effective, custom-tailored optimal disease management for individual patients. To address this challenge, a number of efforts have been made to develop implantable IOP sensors based on electrical readout methods, yet further miniaturization, improved readout distance, and signal-tonoise ratio (SNR) are still desired. In this presentation, I will present a compact, implantable nanophotonic pressure sensor with remote optical readout. The sensor has provided robust measurements of hydrostatic pressure between 0-40mmHg and performed well on table top characterizations, ex-vivo, and in-vivo measurements. Sensor design, fabrication, & characterizations; implantation preparation and procedures, and short-term & long-term in- vivo monitoring will be discussed.
Diabetic-related eye diseases are the most common cause of blindness in the world. Early detection through regular screenings is the most effective treatment for these eye diseases. To improve the efficiency of such screenings, it is very important that effectively finding the presence of abnormalities in the retinal images captured during the screenings. In this paper, it is focused on automatically detecting one of the abnormal signs: the presence of' exudates/lesions in the retinal images. A novel approach that combines median filtering and dynamic clustering analysis is proposed. Experimental results indicate that the new algorithm is easier, faster and more effective for lesion detection from retinal images of various qualities.
To fasten an artificial retinal implant onto the epiretinal surface of the eye, our group has designed retinal microtacks. The microtacks were fabricated using two different micromachining techniques: 1) deep reactive ion etching (DRIE) and 2) ultra-high-precision micromilling. Metrology was performed on each microtack design following fabrication, measuring all critical and overall dimensions. Force measurement experiments were performed to determine the loads required to insert and remove each microtack design in a synthetic material. This was carried out to verify the validity of the new geometric features added to the microtack. Each experiment consisted of three programmed zones: Insertion, Hold, and Removal. The required displacement and velocity were determined for each zone dependent upon microtack design.
We present two early prototype systems that leverage computer memory to augment human memory in everyday situations. Both experiments investigate the role of eye tracking as a way to detect a person's attention and use this knowledge to affect short and long term memory processes. This work is part of a larger effort underway at the MIT Media Laboratory to develop systems that work symbiotically with humans, leading to increased performance along numerous cognitive and physical dimensions [D. Roy].
Resource organization and discovery is one of the important research field in grid computing, however, the present technology and approaches did not consider the mobility of grid resource. As to the complicity of the resource's management in mobile grid, This paper firstly describe three layers resource organization mode; Then present the tree directory resource management which consider the problem of resource's mobility and limited power so avoid the blindness of resource find. At last we propose a way of resource selection algorithm based priority which consider the remained battery power and mobility consideration, and a theoretical complexity analysis is presented as well, In the end, the experiment proved that the algorithm had high efficiency of discovery.
A Mexican Official Standard for accessibility to health-care facilities was developed by an interdisciplinary and inter-institutional group. Because of the North American Free Trade Agreement, the Standard should agree with standards of the United States and Canada. Not all elements for accessibility were included. Decisions on inclusion were based on functionality, durability, safety, cost, weather conditions, anthropometry and literacy; and on the fact that this Standard was for a developing country. The Standard only applies to buildings under construction or being remodeled.
We find that in P300 speller paradigm, there exists difference between electroencephalogram (EEG) signals evoked by flashing adjacent to the row (column) containing the target and those evoked by other non-target stimuli. This difference might arise out of users' perceptual confusion. We use a machine learning approach to learn the difference of this perceptual characteristic, and employ the classifier to aid classification in P300 speller. Experiments show that our method remarkably improves the performance
