Create a QWAimages object

QWAimages is a subclass of data.frame that holds image-level metadata for a QWA dataset. It is the required component of QWAmetadata and can be used as input for collect_raw_data().

Usage

QWAimages(data, roxas_version = NULL)

Arguments

data

A data frame with image-level metadata. Is aligned with the required structure for QWAimages objects and validated against the corresponding JSON schema.

roxas_version

The ROXAS software version: "roxas" or "roxas_ai". If NULL, inferred from the $software column of data.

Value

A QWAimages object with a roxas_version attribute.

Details

Each row represents one image with its associated ROXAS (AI) output file paths, hierarchical labels (site, tree, woodpiece, slide, image), EXIF metadata, and ROXAS (AI) settings. It is typically constructed by build_QWAimages().

The roxas_version attribute records whether the data were produced by classic ROXAS ("roxas") or ROXAS AI ("roxas_ai").
