Calibration Curves: Linear Least Squares

1.4K
A calibration curve is a plot of the instrument's response against a series of known concentrations of a substance. This curve is used to set the instrument response levels, using the substance and its concentrations as standards. Alternatively, or additionally, an equation is fitted to the calibration curve plot and subsequently used to calculate the unknown concentrations of other samples reliably.
For data that follow a straight line, the standard method for fitting is the linear...

Calibration Curves: Correlation Coefficient

1.7K
In a linear calibration curve, there is a value called the calibration coefficient, denoted by 'r,' which measures the strength and the direction of association between two variables. The correlation coefficient value ranges from −1 to +1. A value of +1 indicates a perfect positive linear correlation, −1 denotes a perfect negative correlation, and 0 implies no correlation between the two variables. A positive correlation value establishes that as one variable increases, the...

Accurate calibration of glassware, such as volumetric flasks, pipettes, and burettes, is essential to ensure accurate measurements in the analytical laboratory. Calibration helps maintain consistency across measurements and prevents errors arising from inaccurate volumes.
Volumetric flasks: Volumetric flasks are designed to prepare aqueous solutions of precise volumes accurately with a calibration line on the neck. To calibrate a volumetric flask, it is important to fill it with distilled...

    Summary

    Fixed Pattern Noise (FPN) in digital cameras, caused by sensor imperfections, limits low-light imaging. This study introduces a novel method to remove FPN by scaling a pre-calibrated noise pattern, improving image quality.

    Area of Science:

    • Digital imaging and sensor technology
    • Image processing and signal analysis

    Background:

    • Manufacturing imperfections in digital sensors lead to Fixed Pattern Noise (FPN).
    • FPN significantly degrades image quality, especially in low-light conditions.
    • Existing FPN removal methods may require extensive calibration or lack robustness.

    Purpose of the Study:

    • To propose and validate a novel semi-calibration-based method for Fixed Pattern Noise removal.
    • To address the limitations of current FPN removal techniques in digital imaging.
    • To enhance the performance of digital cameras in low-light environments.

    Main Methods:

    • A novel semi-calibration approach utilizing a pre-calibrated Noise Pattern for FPN removal.
    • Estimation of an unknown scale parameter for the Noise Pattern based on entropy minimization and Maximum Likelihood principle.
