mindspore.dataset.vision
|
||
===================================
|
||
|
||
此模块用于图像数据增强，其中有一部分增强是基于C++ OpenCV实现的，具有较好的性能，而另一部分是基于Python Pillow实现的。
|
||
|
||
API样例中常用的导入模块如下：
|
||
|
||
.. code-block::
|
||
|
||
import mindspore.dataset as ds
|
||
import mindspore.dataset.vision as vision
|
||
import mindspore.dataset.vision.utils as utils
|
||
|
||
注意：旧的API导入方式已经过时且会逐步废弃，因此推荐使用上面的方式，但目前仍可按以下方式导入：
|
||
|
||
.. code-block::
|
||
|
||
import mindspore.dataset.vision.c_transforms as c_vision
|
||
import mindspore.dataset.vision.py_transforms as py_vision
|
||
from mindspore.dataset.transforms import c_transforms
|
||
|
||
更多详情请参考[图像数据加载与增强](https://www.mindspore.cn/tutorials/zh-CN/master/advanced/dataset/augment_image_data.html)。
|
||
|
||
常用数据处理术语说明如下：
|
||
|
||
- TensorOperation，所有C++实现的数据处理操作的基类。
|
||
- PyTensorOperation，所有Python实现的数据处理操作的基类。
