Novel word recognition and word spotting systems for offline Urdu handwriting

Word recognition for offline Arabic, Farsi and Urdu handwriting is a subject which has attained much attention in the OCR field. This thesis presents the implementations of offline Urdu Handwritten Word Recognition (HWR) and an Urdu word spotting technique. This thesis first introduces the creation of several offline CENPARMI Urdu databases. These databases were necessary for offline Urdu HWR experiments. The holistic-based recognition approach was followed for the Urdu HWR system. In this system, the basic pre-processing of images was performed. In the feature extraction phase, the gradient and structural features were extracted from greyscale and binary word images, respectively. This recognition system extracted 592 feature sets and these features helped in improving the recognition results. The system was trained and tested on 57 words. Overall, we achieved a 97 % accuracy rate for handwritten word recognition by using the SVM classifier. Our word spotting technique used the holistic HWR system for recognition purposes. This word spotting system consisted of two processes: the segmentation of handwritten connected components and diacritics from Urdu text lines and the word spotting algorithm. A small database of handwritten text pages was created for testing the word spotting system. This database consisted of texts from ten Urdu native speakers. The rule-based segmentation system was applied for segmentation (or extracting) for handwritten Urdu subwords or connected components from text lines. We achieved a 92% correct segmentation rate for 372 text lines. In the word spotting algorithm, the candidate words were generated from the segmented connected components. These candidate words were sent to the holistic HWR system, which extracted the features and tried to recognize each image as one of the 57 words. After classification, each image was sent to the verification/rejection phase, which helped in rejecting the maximum number of unseen (raw data) images. Overall, we achieved a 50% word spotting precision at a 70% recall rat

Functional Magnetic Resonance Imaging

"Functional Magnetic Resonance Imaging - Advanced Neuroimaging Applications" is a concise book on applied methods of fMRI used in assessment of cognitive functions in brain and neuropsychological evaluation using motor-sensory activities, language, orthographic disabilities in children. The book will serve the purpose of applied neuropsychological evaluation methods in neuropsychological research projects, as well as relatively experienced psychologists and neuroscientists. Chapters are arranged in the order of basic concepts of fMRI and physiological basis of fMRI after event-related stimulus in first two chapters followed by new concepts of fMRI applied in constraint-induced movement therapy; reliability analysis; refractory SMA epilepsy; consciousness states; rule-guided behavioral analysis; orthographic frequency neighbor analysis for phonological activation; and quantitative multimodal spectroscopic fMRI to evaluate different neuropsychological states

Eye Movement Metrics in the Differentiation of Parkinsonian Syndromes.

Oční pohyby v diferenciaci parkinsonských syndromů MUDr. Cecilia Bonnet Shrnutí dizertační práce pro obhajobu PhD., Univerzita Karlova, Praha 2017 V této práci jsme zkoumali konjugované a dyskonjugované oční pohyby (EM) u Parkinsonovy nemoci (PD) a dalších parkinsonských syndromů s cílem charakterizovat a diferencovat některé aspekty jejich okulomotoriky pomocí infračervené videookulografie (VOG). Nejprve jsme zveřejnili přehledový článek popisující klinické vyšetření očních pohybů a interpretaci hlavních nálezů. Poté jsme zkoumali sakadické a sledovací oční pohyby v horizontálním a vertikálním směru ve velké skupině zdravých subjektů s cílem získat vlastní normy a pomoci okulografickým laboratořím při sestavování vlastních norem. Dospěli jsme k závěru, že věk, ale nikoliv pohlaví nebo vzdělání ovlivňuje metriky EM. Zvyšuje se latence sakád a chybovost antisakád, zatímco rychlost a zisk se s věkem snižují. Ve třetím projektu jsme se zaměřili na časté zrakové obtíže pacientů s PD, zejména rozmazané vidění na blízko a zrakové nepohodlí při čtení. Objektivně jsme poprvé zkoumali vergenční oční pohyby (VEM) u pacientů s PD s použitím VOG. Pacienti vykazují zvýšenou latenci VEM a divergence je pomalá a hypometrická.

First of all we published a practical review for medical students and clinicians describing clinical examination of eye movements, and interpretation of principal findings. Then we examined principal saccadic eye movements and smooth pursuit in the horizontal and vertical directions with video-oculography in a large group of healthy subjects, aiming to help new oculomotor laboratories in the constitution of their own norms. We conclude that age influence EM metrics but not gender or education level. The latency of saccades and the error rate of antisaccaes increases, while the velocity and gain diminishes with age. Saccades should be investigated in the horizontal and vertical plane because they are influenced by the direction of the target, resulting in a right/left and up/down asymmetry. In a third project we focused on a frequent complain of PD patients, namely blurred near vision and...Department of Neurology First Faculty of Medicine and General University Hospital in PragueNeurologická klinika 1.
