SimpleAUG 0.0.1

A simpler imgaug tool

SimpleAUG 更加简单的数据增强库

使用示例

数据增强的具体配置可以到overview_of_augmenters.html查阅

from imgaug import augmenters as iaa
from simpleaug import aug

# 输入VOC数据集的路径
XML_DIR = "/demo/VOC_MASK/Annotations/"
IMG_DIR = "/demo/VOC_MASK/JPEGImages/"

# 数据增强后的存储路径
AUG_XML_DIR = "/demo/VOC_MASK_AUG/Annotations/"  # 存储增强后的XML文件夹路径
AUG_IMG_DIR = "/demo/VOC_MASK_AUG/JPEGImages/"  # 存储增强后的影像文件夹路径

# 数据增强配置
AUGCONF = [
    # iaa.Invert(0.5),
    iaa.Fliplr(0.5),
    iaa.Multiply((1.2, 1.5)),  # change brightness, doesn't affect BBs
    iaa.GaussianBlur(sigma=(0, 3.0)),  # iaa.GaussianBlur(0.5),
    iaa.Affine(
        translate_px={"x": 15, "y": 15},
        scale=(0.8, 0.95),
    ),  # translate by 40/60px on x/y axis, and scale to 50-70%, affects BBs
    iaa.Sometimes(
        0.5,
        iaa.GaussianBlur(sigma=2.0),
        iaa.Sequential([iaa.Affine(rotate=45), iaa.Sharpen(alpha=1.0)])
    )
]
