import_process_image: Import and Process a .tiff or .tif image

In wesleyburr/magneto: The building blocks for digitization of magnetograms, or images alike

Import and Process a .tiff or .tif image

Description

Import and Process a .tiff or .tif image

Usage

import_process_image(
  imageName,
  file_loc,
  trimAmountTop = 100,
  trimAmountBottom = 50,
  beta0 = -2.774327,
  beta1 = 51.91687,
  cutoffProbability = 0.5,
  NADefault = 0,
  FilterBright = c(13, 13),
  FilterNonBright = c(8, 8),
  methodBright = "delation",
  methodNonBright = "delation",
  thresholdBright = 0.8,
  thresholdNonBright = 0.5
)

Arguments

imageName	The name of the file
file_loc	the path from ~/ to the dir where the file is
trimAmountTop	Number of pixels off of top of image (usually for common flares)
trimAmountBottom	Number of pixels off of bottom of image
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 found in the matrix
FilterBright	Vector specifying the dimensions of the kernel, which will be used to perform either delation or erosion, such as c(13,13)
FilterNonBright	Vector specifying the dimensions of the kernel, which will be used to perform either delation or erosion, such as c(8,8)
methodBright	one of 'delation'(adds to image, making brights brighter), 'erosion' (subtracts from image brights darker)
methodNonBright	one of 'delation'(adds to image, making brights brighter), 'erosion' (subtracts from image brights darker)
thresholdBright	should be between 0 and 1 for normalized images Default = 0.8
thresholdNonBright	should be between 0 and 1 for normalized images Default = 0.5

Value

imageMatrix processed and trimed, in landscape orientation
