i am thinking about using a CNN to classify certain images from industrial production, like scratches, stain, particles etc.
the problem is we don't have many images. We only get around 10 parts with certain defects to detect. I thought about using a database with different defects on it.
I use the example of scratches, there are around 100 images of scratches. Now my question:
Does it make sense to rotate the images in all 4 orientation, and to mirror them as well? So i would get 8 images (the original + 7 uniformly transformed images), i know the "value" of the rotated and mirrored images is not as high as from real images, but it should still help the CNN to abstract and find features.
What do you think about it?
Thanks in advance!
