A Geometric Approach to Light field Calibration
1999Light field rendering allows fast visualization of complex scenes by view interpolation from images of densely spaced camera view-points. The light field data structure requires calibrated viewpoints, and rendering quality can be improved substantially when local scene depth is known for each viewpoint.

Calibrated Approach to Endoscopico Sinus Surgery
Annals of Otology, Rhinology & Laryngology, 1990Endoscopic sinus surgery, in which the surgeon views the nose and paranasal sinuses through a telescope, can potentially lead to loss of perspective of the patient's entire head. Preoperative computed tomographs are also taken at angles different from those encountered in the surgical setting.

A robust numerical approach for array calibration
IEEE International Conference on Acoustics Speech and Signal Processing, 1993The authors focus on the problem of sensor array calibration in the presence of noise field uncertainties. The objective is to compute a reliable estimate of the array response vector given finite sample estimates of the signal plus noise and noise only array covariances.

Guaranteed Approach to Accelerometer Unit Calibration
2019 6th International Conference on Control, Decision and Information Technologies (CoDIT), 2019The paper focuses on the calibration problem for the accelerometer unit at a high precision test bench. Besides instrument errors of the accelerometer unit itself, possible errors of the test bench are also considered. One of the main problems is to choose the optimal design of the angular positions for the unit.

A novel geometric approach for camera calibration
2014 IEEE International Conference on Image Processing (ICIP), 2014In this paper, we propose a novel geometric approach for solving camera calibration efficiently. Our camera calibration procedure is implemented on planar objects with rectangles on them. Images of the planar object are taken from different views where corner features are extracted.

Calibration ? A multidimensional approach
Fresenius' Journal of Analytical Chemistry, 1995Analytical calibration, in its entirety, comprises both qualitative and quantitative analysis and has to be considered, therefore, from a multidimensional point of view. The relationships must be characterised between the presence of certain analytes and typical signal patterns (e.g.

A Calibration Approach for Accuracy Infrared Temperature
2016 International Conference on Intelligent Networking and Collaborative Systems (INCoS), 2016The measurement of temperature of infrared image is widely used in the test field which bring much convenience. In the measuring temperature system, measurement accuracy is an imperative problem. The accuracy is influenced by many factors. The calibration based on distance segmentation parameters will be solved and the effect of other factors will be ...

A stratified approach to metric self-calibration
Proceedings of IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2002Camera calibration is essential to many computer vision applications. In practice this often requires cumbersome calibration procedures to be carried out regularly. In the last few years a lot of work has been done on self-calibration of cameras, ranging from weak calibration to metric calibration.

A Confirmatory Approach To Calibration Congeneric Measures
Multivariate Behavioral Research, 1980This paper demonstrates how the problem of calibrating measures can be formulated in terms of confirmatory factor analysis. The relationships between traditional approaches (Angoff, 1971) and a confirmatory factor approach are specified.

Applying the Calibration Approach
1999The application of the variance bound approach in the previous chapter has given a first impression of the capability of the different parametric models of the market pricing kernel to jointly price different assets. Now, the calibration approach described in chapter 5 is applied to quarterly German data for the period 1960 to 1994.
