gimp-labeling-converter 2.0.0

it provides a CLI tool that converts XCF file to a new format suitable for labeling. The tool also make the users able to add their own handlers for addling support to other types of outputs.

GIMP Labeling Assistance

Converting images labeled by GIMP to different formats

GNU Image Manipulation Program

GIMP (GNU Image Manipulation Program) is a free and open-source raster graphics editor used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is not designed to be used for drawing.

Labeling Procedure

GIMP is a powerful photo editing software which has great potential to be used as a labeling software for semantic segmentation. To do so, we provide a procedure for labeling images using GIMP software,

• Load an image into the software.
• Review the image to find candidate classes.
• Create a layer for each class (make sure that the background is transparent)
• Use pen tool and select a color (make sure the "hardness" and "opacity" properties are set to 100.
• Draw the areas belong to the class associated to the selected layer.
• Change the layer and repeat the labeling steps.
• Save the image as "xcf" file format.

Program

This repository provides a CLI tool that converts XCF file to a new format suitable for labeling. The tool also make the users able to add their own handlers for addling support to other types of outputs. Currently, the tool supports two handlers,

• mask : convert the xcf files to a multiple folders named after extracted classes. Each folder contains the mask presenting the areas labeled as the associated class.
• coco : convert the xcf files to a single MS COCO file (JSON).
• class_map : convert the xcf files to images that each pixel labeled as its class index.

The cli tool can be initialized in two ways: (a) using config files, and (b) using commandline arguments.

Options

The CLI tool provides the following options,

Options	Other forms	Description
--dir_in	--dir -d	Directory containing the images.
--file_out	--out -o	Output Directory
--handler	--type	Handler Type [initially "mask", "class_map" and "coco"]
--num_worker	-w	Number of Workers
--config		Configuration file path
--name	-n	Set dataset name
--info		Set description
--url		Set URL
--version		Set version
--year		Set Year
--contrib		Set contributor
--category	-c	Class Categories

Usage

Using options

gimp_labeling_converter --dir "/home/phm/my-dataset/labeled" \
                --out "/home/phm/Documents/dataset" \
                --type "mask" -w 5 \
                -c "defect" -c "surface_defect" \
                -n "Parham Test"

or

gimp_labeling_converter --dir "/home/phm/my-dataset/labeled" \
                --out "/home/phm/Documents/dataset/test.json" \
                --type "coco" -w 5 \
                -c "defect" -c "surface_defect" \
                -n "Parham Test" --info "Testing the coco handler" \
                --url "linkedlist.com" \
                --version "1.0.0" --year 2022 --contrib "Parham Nooralishahi"

Using config file

Assuming the config file named as "./coco.json",

gimp_labeling_converter --config "./coco.json"
