Project description
mask2json
a small tool for image augmentation, including mask files to json/xml files , image augmentation(flip,rotation,noise,...) and so on
HOW TO USE
This script is used to convert mask-labels to json files for labelme.
Also ,json files to masks can be found on this site. Sometimes there will be an ERROR,should add this file in labelme path ('../anaconda/Lib/site-packages/labelme/utils ' my path) and add some codes in __init__.py:
from .draw import label_colormap
from .draw import _validate_colormap
from .draw import label2rgb
from .draw import draw_label
from .draw import draw_instances
Here shows an example using this script.
origin image
mask image
manually_labeled image
auto_labeled image
Also ,for labelimg,a small tool to convert results(yolo) to xml-files. (I tested single object but didn't test multi objects
(1) for labelme mask files
the test script can be found here
from utils import getMultiShapes
getMultiShapes.getMultiShapes(param1,param2,param3,param4)
param1:path which saves the origin imgs
param2:path which saves the mask imgs (file names should match the origin imgs)
param3:converted json files save path
param4:can be blank (better don't), a yaml file path which saves the class information
(2) for labelimg mask files
the test script can be found here
from utils.getMultiShapes import getMultiObjs_voc as gvoc
gvoc(param1,param2,param3)
param1:path which saves the origin imgs
param2:path which saves the mask imgs (file names should match the origin imgs)
param3:converted xml files save path
(3) for json files to mask files
the test script can be found here
from utils.convert import processor
processor(param1,param2)
param1:json file or folder
param2:can be blank,encoding type, default 'utf-8'
AILERNATIVE
you can try:
pip install convertmask
it is a test release. : )
SHORTCOMING
1.objects connected to each other is not supported yet.
this may happen if you labelling multiple-object-images with only 2 labels .Or some objects are of the same type and are connected to each other(eg. a bunch of grapes,it is hard to split one to the other).
LOGS
2020.6.12
support multiple objects mask to json
try test.py !
multiple objects in different classes
manually_labeled image
auto_labeled image
multiple objects in same classes
manually_labeled image
auto_labeled image
2020.7.10
a lot of things to do ,such as many warnings related to labelme.
2020.7.13
convert multi objects to xml files supported (untested)
2020.7.14
bugfix , test multi objects to xml files, pretty xmls
eg:
2020.7.17
is going to support image augmentation !!
2020.8.14
add image augmentation (image flip) test. see test_imgAug.py !
2020.8.17
bug fix.
support image augmentation methods: noise,flip,rotation. try test_imgAug.py !
here are some examples:
flip
noise
rotation
2020.8.19
image translation supported.
combination of every augmentation method.
besides, a simple way convert json file(labelme) to xml file(labelImg) is provided. see here
