augment.md

This function is used to augment images, labels,masks, jsons and xmls.

How to use.

1.For labelme(images and jsons).

from convertmask.utils.imgAug import imgFlip, imgNoise, imgRotation, imgTranslation, aug_labelme, aug_labelimg, imgZoom
import os
from skimage import io
from convertmask.utils.getMultiShapes import getMultiShapes

BASE_DIR = os.path.abspath(os.path.dirname(os.getcwd())) + os.sep + 'static'
imgPath = BASE_DIR + os.sep + 'multi_objs.jpg'
labelPath = BASE_DIR + os.sep + 'multi_objs.json'

if __name__ == "__main__":

    #### test1

    imgFlip(imgPath, labelPath)

    imgNoise(imgPath, labelPath)

    imgRotation(imgPath, labelPath)

    imgTranslation(imgPath, labelPath)

    imgZoom(imgPath, labelPath, 1.2)

    #### test2

    n = imgNoise(imgPath, labelPath, flag=False)

    tmp = n['noise']

    img, processedImg = tmp.oriImg, tmp.processedImg

    r = imgRotation(img, processedImg, flag=False, angle=15)

    tmp = r['rotation']

    img, processedImg = tmp.oriImg, tmp.processedImg

    t = imgTranslation(img, processedImg, flag=False)

    tmp = t['trans']

    img, processedImg = tmp.oriImg, tmp.processedImg

    f = imgFlip(img, processedImg, flag=False)

    tmp = f['h_v']

    img, processedImg = tmp.oriImg, tmp.processedImg

    parent_path = os.path.dirname(imgPath)

    if os.path.exists(parent_path + os.sep + 'jsons_'):
        pass
    else:
        os.makedirs(parent_path + os.sep + 'jsons_')
    fileName = 'test'
    io.imsave(
        parent_path + os.sep + 'jsons_' + os.sep + fileName + '_assumble.jpg',
        img)

    assumbleJson = getMultiShapes(parent_path + os.sep + 'jsons_' + os.sep +
                                fileName + '_assumble.jpg',
                                processedImg,
                                flag=True,
                                labelYamlPath='')

    saveJsonPath = parent_path + os.sep + 'jsons_' + os.sep + fileName + '_assumble.json'

    with open(saveJsonPath, 'w') as f:
        f.write(assumbleJson)

    #### test3

    aug_labelme(imgPath, labelPath)

2.For labelImg(images and xmls).

Just same as 'For labelme(images and jsons)'. For more detailed information,see here
