Detailed Description

This simple tool looks for classes named "TL", "TR", "BL", and "BR". This is typically used to indicate the corners of objects, where "TL" is "top-left", "BR is "bottom-right", etc. If it finds any of these classes, the tool will then read through all of the existing annotations, resize the corners to a specific size, and re-write the annotation files with the new sizes.

Function Documentation

find_all_images()

void find_all_images

(

const std::filesystem::path &

root_directory

)

Perform a recursive directory search to find all the images.

Then we exclude anything in DarkMark's image cache or which doesn't have an annotation file. Results are stored in the global variable annotated_image_filenames.

void parse_names_file

(

const std::filesystem::path &

names_file

)

Read the .names file and find all of the corner indexes we need to resize.

These classes will have names such as TL, TR, BR, and BL. The search for names is case-insensitive.
