This paper presents the design and implementation of an intelligent document understanding and reproduction system. The system analyses a printed document to create an electronic document. The electronic document is written in a standard type-setting language (L w), and is thus human usable. The output from processing the electronic document closely(More)
BACKGROUND Canadian provinces boast one of the most sophisticated telemedicine infrastructures in the world. Feasibility of epilepsy care through telemedicine is established, but its use by practicing neurologists is unknown. The Canadian League against Epilepsy's telemedicine task force conducted this study to understand the perceptions, barriers and usage(More)
Partial seizures of temporal origin can be associated with clinically significant tachycardia or bradycardia. Ictal bradycardia and asystole has been implicated in the etiology of sudden unexpected death in epileptic patients (SUDEP). Although symptomatic ictal bradycardia has been relatively well described in the literature; information on asymptomatic(More)
In children with medically intractable seizures, epilepsy surgery is now a widely accepted option. Successful discontinuation of antiepileptic drugs after epilepsy surgery has been reported in adults, but rarely in children. Surgical outcome and need for antiepileptic drugs after temporal and extratemporal lobe resection were retrospectively reviewed for 80(More)
Intermittent photic stimulation (IPS) is an activating procedure meant to elicit or accentuate epileptiform discharges during an EEG. There is insufficient clinical data to advocate IPS in the routine EEGs of all adult patients. We therefore sought to address the clinical significance of routine IPS in the adult population. We retrospectively reviewed 100(More)
OBJECTIVE Our main objective was to use videoconferencing as a primary means to: a) assist in launching an epilepsy surgery program in Pakistan; 2) participate in case conferences on complex epilepsy patients in each country. METHODS Extensive testing using both point to point and bridged integrated service digital network (ISDN) and internet protocol(More)
BACKGROUND Ictal and postictal language dysfunction is common and strongly predictive of language laterality in monolingual patients. For bilingual patients, selective dysfunction has been reported for a single language with focal cerebral lesions, electrical brain stimulation, and intracarotid sodium amytal. METHODS Two right-handed Ukrainian-English(More)
The conversion of an electronic document to a printed document is a relatively simple task, however the reverse transformation is not. The IDUR project has developed an intelligent document understanding and reproduction (IDUR) system. Given a digital document image, the IDUR system produces a L A T E X le. Two features are expected of the L A T E X le.(More)
In the diagnosis of various brain disorders by analyzing the brain magnetic resonance images (MRI), the segmentation of corpus callosum (CC) is a crucial step. In this paper, we propose a fully automated technique for CC segmentation in the T1-weighted midsagittal brain MRIs. An adaptive mean shift clustering technique is first used to cluster homogenous(More)
