Image Processing Based Calibration of High Precision Laser Projection Systems
Large-scale laser projection systems used in industrial environment, e.g. for the projection of CAD drawings onto large work pieces, require external calibration to ensure constant precision and hence quality. Basically, each different projected pattern has to be calibrated at least once, to account for temperature-induced variations in the laser scanning systems, relative displacements due to ...
متن کاملFast FFT-based motion compensation for laryngeal high-speed videoendoscopy
(HSV) are compared. Two of them are based on tracking the maximum of the cross-correlation function of two images; two are based on minimization of the L 2 –norm and L 2-like distance between two images ; and the other two make use of the peak present in the cross-power FFT-based spectrum of two images. All six methods are applied to compensate the motion, at the sub-pixel level, of the endosco...
متن کاملClinical implementation of laryngeal high-speed videoendoscopy: challenges and evolution.
High-speed videoendoscopy (HSV) captures the true intracycle vibratory behavior of the vocal folds, which allows for overcoming the limitations of videostroboscopy for more accurate objective quantification methods. However, the commercial HSV systems have not gained widespread clinical adoption because of remaining technical and methodological limitations and an associated lack of information ...
متن کاملUsual to Particular Phonatory Situations Studied with High-speed Videoendoscopy
Current high-speed videoendoscopy (HSV) make it possible to obtain 4000 images of the larynx per second. By this process, the analysis of the vocal folds can provide significant information. This is also possible to estimate the area of the glottis. All this information is useful for the study of the various phonatory modes, but also for glottal flow estimation which allows the improvement of o...
متن کاملReliability of a transnasal flexible fiberoptic in-office laryngeal biopsy.
IMPORTANCE Transnasal fiberoptic laryngoscopy (TFL) has been used to guide various in-office procedures for the past 3 decades. Publications on in-office laryngeal biopsy have concurred that this procedure is safe, feasible, and easy to perform. However, the accuracy of in-office biopsy via TFL has not yet been established. The aim of this study was to examine this issue. OBJECTIVE To compare...
