A New Approach to Ultrasound Guided Radio-Frequency Needle Placement
The transformation from an ultrasound (US) image plane to the coordinate system of a position sensor attached to the US transducer can be computed with US calibration algorithms. T...

Generalized Blind Mismatch Correction for a Two-Channel Time-Interleaved ADC: Analytic Approach
—Time-interleaved analog-to-digital converters (TIADC) require mismatch calibration to achieve high signal-to-noise ratios. In this paper, we present a new blind technique for M=...

Learning from other subjects helps reducing Brain-Computer Interface calibration time
A major limitation of Brain-Computer Interfaces (BCI) is their long calibration time, as much data from the user must be collected in order to tune the BCI for this target user. I...

Neurocalibration: A Neural Network That Can Tell Camera Calibration Parameters
Camera calibration is a primary crucial step in many computer vision tasks. In this paper we present a new neural approach for camera calibration. Unlike some existing neural appr...

Autocalibration in the Presence of Critical Motions
Autocalibration is a difficult problem. Not only is its computation very noisesensitive, but there also exist many critical motions that prevent the estimation of some of the came...
