Summarize PNG Image Metadata

This function processes IFCB data by reading images, matching them to the corresponding header and feature files, and joining them into a single dataframe. This function may be useful when preparing metadata files for an EcoTaxa submission.

Usage

ifcb_summarize_png_metadata(
  png_folder,
  feature_folder = NULL,
  feature_version = NULL,
  hdr_folder = NULL
)

Arguments

png_folder

Character. The file path to the folder containing the PNG images.

feature_folder

Character. The file path to the folder containing the feature files (optional).

feature_version

Optional numeric or character version to filter feature files by (e.g. 2 for "_v2"). Default is NULL (no filtering).

hdr_folder

Character. The file path to the folder containing the header files (optional).

Value

A dataframe that joins image data, header data, and feature data based on the sample and roi number.

Examples

if (FALSE) { # \dontrun{
png_folder <- "path/to/pngs"
feature_folder <- "path/to/features"
hdr_folder <- "path/to/hdr_data"
result_df <- ifcb_summarize_png_metadata(png_folder, feature_folder, hdr_folder)
} # }
