v0.9.0

This release only supports Chainer v4 and not Chainer v3.
For those users using Chainer v3, please update the version of Chainer or use ChainerCV v0.8.

Spotlight Feature

• Slicable datasets (chainercv.chainer_experimental.datasets.slicable, tutorial). All dataset classes in ChainerCV support the functionality.

API Changes

We renamed APIs relating to points.

• Change name to CUBPointDataset and add tests #528
• Change naming conventions in transforms for points #526
• vis_keypoint --> vis_point #525

Some public attributes of datasets have been changed

• Use SliceableDataset #457

We improved and renamed the method apply_to_iteartor

• apply_prediction_to_iterator --> apply_to_iterator #523

We changed the interface of vis_semantic_segmentation to be consistent with the rest of the visualizers.

• Change vis_semantic_segmentation to take image #576
