R Documentation

Annotate captchas with their labels

Description

Given one or more Captchas, this function prompts the user to solve them manually to train a model. Annotated captchas are saved at path with their labels in the filename separated by an underscore.

Usage

captcha_annotate(files, labels = stdin(), path = NULL, rm_old = FALSE)

Arguments

`files`	Either an object of class `captcha` or a character vector with the paths to captcha files
`labels`	Either `stdin()` (the default, for interactive classification) or a character vector with labels for the Captchas. See details.
`path`	Where to save the annotated captcha files. If `NULL`, saves the files in the same folder the unanswered counterparts.
`rm_old`	Whether or not to delete unanswered captchas after copying and renaming them.

Details

The ⁠labels=⁠ parameter can handle situations where one knows the Captcha label. For example, a workflow that uses an oracle might provide the label automatically. When the label doesn't exist, the captcha_annotate() function opens the prompt for classification and shows the image using plot().
