bright: Checking For Bright Images

In Bott-binc/magnetoPackage2020: The building blocks for digitization of magnetograms, or images alike

Checking For Bright Images

Description

Using a logistic regression to find coefficients, uses the result to compute a probability of the imageMatrix being #'bright (392 observations) with McFadden Pseudo- $R^2$ Value 0.2573778

Usage

bright(
  imageMatrix,
  beta0 = -2.774327,
  beta1 = 51.91687,
  cutoffProbability = 0.5,
  NADefault = 0
)

Arguments

imageMatrix	imageMatrix points representing the brightness of that pixel
beta0	The intercept of a logistic regression default is for magnetograms
beta1	The slope of the logistic regression default is for magnetograms
cutoffProbability	The probability cut off for the decision of an imageMatrix being bright
NADefault	The default value set to NA's in the matrix

Value

The decision of the image being bright (based off of the cutoffProbability)
