Function to check results of classification manually — vpr_manual

Displays each image in day hour specified, prompts user to confirm or deny classification. If classification is denied, asks for a reclassification value based on available category

vpr_manual_classification(
  day,
  hour,
  basepath,
  category_of_interest,
  gr = TRUE,
  scale = "x300",
  opticalSetting = "S2",
  img_bright = TRUE,
  threshold_score,
  path_score
)

Arguments

day: day of interest in autoid (3 chr)
hour: hour of interest in autoid (2 chr)
basepath: path to folder containing autoid files (e.g., 'extdata/COR2019002/autoid')
category_of_interest: list of category folders you wish you sort through
gr: logical indicating whether pop up graphic menus are used (user preference - defaults to TRUE)
scale: argument passed to image_scale, default = 'x300'
opticalSetting: specifies optical setting of VPR, defining image frame size, current options are 'S0', 'S1', 'S2' (default), 'S3', see further info in details
img_bright: logical value indicating whether or not to include a blown out high brightness version of image (can be helpful for viewing dark field fine appendages)
threshold_score: (optional) a numeric value defining the minimum confidence value, under which automatic classifications will be passed through manual reclassification. This argument should match the threshold provided in vpr_autoid_copy()
path_score: (optional) file path to the autoid_cnn_scr folder (autoid files with confidence values produced by automated classification)

Details

Optical Setting frame sizes: S0 = 7x7 mm, S1 = 14x14mm, S2 = 24x24mm, S3 = 48x48 mm. These settings define the conversion factor from pixels to millimetres and calculate image size for classification reference

Development

Add "undo" functionality to go back on a typing mistake
Fix scaling/ size issue so images are consistently sized
