Adaptive System Identification in the Short-Time Fourier Transform Domain Using Cross-Multiplicative Transfer Function Approxima
In this paper, we introduce cross-multiplicative transfer function (CMTF) approximation for modeling linear systems in the short-time Fourier transform (STFT) domain. We assume tha...

Spike-frequency adaptation generates intensity invariance in a primary auditory interneuron
Adaptation of the spike-frequency response to constant stimulation, as observed on various timescales in many neurons, reflects high-pass filter properties of a neuron's tran...

Sensitivity of Time Response to Characteristic Ratios
In recent works [1], [5], it has been shown that the damping of a linear time invariant system relates to the so-called characteristic ratios (k, k = 1,

Automatic Adjustment of Transfer Functions for 3D Volume Visualization
In most volume rendering scenarios implicit classification is performed manually by specification of a transfer function, that maps abstract data values to visual attributes. An a...

Multi-Electrode Spike Sorting by Clustering Transfer Functions
A new paradigm is proposed for sorting spikes in multi-electrode data using ratios of transfer functions between cells and electrodes. It is assumed that for every cell and electr...

Texture Partitioning and Packing for Accelerating Texture-based Volume Rendering
To apply empty space skipping in texture-based volume rendering, we partition the texture space with a box-growing algorithm. Each sub-texture comprises of neighboring voxels with...
