OBJECTIVE We examined the eye movement response patterns of a group of patients with bilateral vestibular loss (BVL) during suppression head impulse testing. Some showed a new saccadic strategy that may have potential for explaining how patients use saccades to recover from vestibular loss. METHODS Eight patients with severe BVL [vestibulo-ocular reflex (VOR) gains less than 0.35 and absent o...

This analysis assesses sensitivity of primate ganglion cells to sinusoidal modulation as a function of temporal frequency, based on the structure of their impulse trains; sensitivity to luminance and chromatic modulation was compared to human psychophysical sensitivity to similar stimuli. Each stimulus cycle was Fourier analyzed, and response amplitudes subjected to neurometric analysis; this a...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...

We present a novel reformulation of balanced truncation, classical model reduction method. The principal innovation that we introduce comes through the use system response data has been either measured or computed, without reference to any prescribed realization original model. Data are represented by sampled values transfer function impulse corresponding discuss parallels our approach bears wi...

Temporal processing is different in the periphery than in the fovea. Two measures of temporal sensitivity, increment thresholds for onset asynchrony and temporal modulation thresholds (flicker), were studied in the fovea and at 20 deg in the lower visual field. The ability to detect incremental changes in the time between the onsets of two vertical lines was generally more precise in the fovea ...

Using a model of the functional MRI (fMRI) impulse response based on published data, we have demonstrated that the form of the fMRI response to stimuli of freely varied timing can be modeled well by convolution of the impulse response with the behavioral stimulus. The amplitudes of the responses as a function of parametrically varied behavioral conditions are fitted well using a piecewise linea...

This paper describes a new method for linear phase finite impulse response (FIR) filters design. This new approach, based on the ε-insensitive loss function, allows the design process to take into account not only constraints specified in the frequency domain, but also constraints on the output, time domain, signal. The performances of the proposed approach are shortly illustrated by a high-pas...
