Scaling in Augmentation

[Bayrambai]

Thanks for making your code open,

Can you tell me how do you obtain [0.93, 1] scaling for size [256, 832] in your Augmentation? Is scaling dependent on the resized image?

Hi, The two parameters are independent.

You can intuitively think that (although the actual implementation is a bit different):

• First, it generates an intermediate image by resizing with the random scale between [0.93, 1] + random rotation and translation)
• and then it crops a rectangle with the size of [256. 832]

So, you can freely change the two parameters as you wish. However, there is a stage that discards an invalid configuration such as when the intermediate image is smaller than the crop size. This kind of case will not be used for training.
