Extract Taxa Images from MATLAB Classified Sample

This function reads a MATLAB classified sample file (.mat) generated by the `start_classify_batch_user_training` function from the `ifcb-analysis` repository (Sosik and Olson 2007), extracts specified taxa images from the corresponding ROI files, and saves each image in a specified directory.

ifcb_extract_classified_images(
  sample,
  classified_folder,
  roi_folder,
  out_folder,
  taxa = "All",
  threshold = "opt"
)

Arguments

sample

A character string specifying the sample name.

classified_folder

A character string specifying the directory containing the classified files.

roi_folder

A character string specifying the directory containing the ROI files.

out_folder

A character string specifying the directory to save the extracted images.

taxa

A character string specifying the taxa to extract. Default is "All".

threshold

A character string specifying the threshold to use ("none", "opt", "adhoc"). Default is "opt".

Value

No return value, called for side effects. Extracts and saves taxa images to a directory.
