Hacking: Data augmentation

  • UNET

  • "Horizontal flips • Image rotation up to ±30◦ • Addition of Gaussian blur with 2≤ σ ≤7 • Random Gamma correction for γ =[0.6, 0.8, 1.2, 1.4] • Exposure offset up to ±25 levels • Gaussian noise with 2≤ σ ≤16 • Image corruption by masking out pixels along a four-pixel thick line • No augmentation" Kothari, Rakshit S., Aayush K. Chaudhary, Reynold J. Bailey, Jeff B. Pelz, and Gabriel J. Diaz. "Ellseg: An ellipse segmentation framework for robust gaze tracking." IEEE Transactions on Visualization and Computer Graphics 27, no. 5 (2021): 2757-2767.
