add rotation augmentation

[hcx1231]

In some cases, like industrial inspection, rotation is a natural scene as horizontal flip,so I added it to the transform process in training time.Default was set to 0.0.

Does this work? When i ran this, i got size inconsistent error in cat boxlist.

F.resize parameter order is height, width,
image.size's parameter order is width height

so, to correct this

width, height = image.size
image = F.rotate(image,90,expand=True)
image = F.resize(image, (height, width))

is necessary

I am so sorry.I have resized to keep it the same size with the input box and ran OK in my own dataset.Let me check it and answer you later.

@hcx1231 Hi, have you tested your implementation on COCO dataset? And do you have an improvement on COCO minival dataset?

How can I generate a random rotation angle by your code? Thanks
