convertmask 0.3.2

a small tool for image augmentation, including mask files to json/xml files , image augmentation(flip,rotation,noise,...) and so on

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.

(1) for labelme mask files

the test script can be found here

from mask2json_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 mask2json_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 mask2json_utils.convert import processor
processor(param1,param2)

param1:json file or folder

param2:can be blank,encoding type, default 'utf-8'

(4) for json files to xml files

the test script can be found here

from mask2json_utils.json2xml import j2xConvert
j2xConvert(path-of-your-jsonfile)

(5) image augmentation

the test script can be found here

from mask2json_utils.imgAug import imgFlip,imgNoise,imgRotation,imgTranslation,aug_labelme

imgFlip(imgPath, labelPath)
imgNoise(imgPath,labelPath)
imgRotation(imgPath,labelPath)
imgTranslation(imgPath,labelPath)

AILERNATIVE

you can try:

pip install -U convertmask

and

pip uninstall convertmask

to delete convertmask.

it is a test release. : )

version 0.3.1 (2020.8.20 , pre-release)

1.try :

convertmask -h | --help

to read the guide.

2.try:

convertmask -v | --version

to show the current version

3.try:

convert m2j 

to test mask to json function(should type in some file path)

4.try:

convert m2x 

to test mask to xml function(should type in some file path)

3.try:

convert j2m 

to test json to mask function(should type in some file path)

3.try:

convert j2x 

to test json to xml function(should type in some file path)

3.try:

convert aug 

to test image augmentation function(should type in some file path)

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).

CHANGE LOGS

2020.6.12

1.support multiple objects mask to json

try test.py !

1.1 multiple objects in different classes

manually_labeled image

auto_labeled image

1.2 multiple objects in same classes

manually_labeled image

auto_labeled image

2020.7.10

1. a lot of things to do ,such as many warnings related to labelme.

2020.7.13

1. convert multi objects to xml files supported (untested)

2020.7.14

1.bugfix , test multi objects to xml files, pretty xmls

eg:

2020.7.17

1. is going to support image augmentation !!

2020.8.14

1. add image augmentation (image flip) test. see test_imgAug.py !

2020.8.17

1. bug fix.

2. support image augmentation methods: noise,flip,rotation. try test_imgAug.py !

here are some examples:

flip

noise

rotation

2020.8.19

1. image translation supported.

combination of every augmentation method.

2. besides, a simple way convert json file(labelme) to xml file(labelImg) is provided. see here

what to do next

1. support multiple files image augmentation

2. support image augmentation without a label/json file

3. support image augmentation with a labeled file (just support json file right now)

4. image augmentation supports custom parameters (auto augmented right now)

5. do something more interesting
