About img augmentation #29

Closed w19787 closed 4 years ago

w19787 commented 4 years ago

there is img augmentation for moving image. Is it ok to apply same augmentation to the fixed image? I am asking this question since in my case, the dataset is much smaller, if there is no concern, I will try to add augmentation for both images.

image

Yes, but should be careful about how the point1 will be augmented along with the fixed image. An inverse field should be computed.

i am not sure i understand what you say. if i apply same code as follows to fixed image(img1), what will be problem?

augImg1 = augmentation(preprocessedImg1)
augSeg1 = augmentation(seg1)
augPt1 = augmenetation_pts(point1)

Sorry I was wrong that here we don't have a flow to worry about. This seems very OK!
