RICAP

  • Random image Cropping and patching
  • Cropping four regions from randomly sampled images and augmenting them to create a new image.
  • The generated image has mixed labels proportional to the pasted area
  • The area of cropped regions in the output image is determined by sampling through uniform distribution
  • anywhere-RICAP (origin can be anywhere), center-RICAP (origin can only be in the middle of the image), and corner-RICAP (origin can only be in corners
  • Corner-RICAP has shown the best performance because a larger region of one image is visible to the network to learn
