Wide2Long: Learning Lens Compression and Perspective Adjustment for Wide-Angle to Telephoto Translation

ICCV 2025poster

A translation framework that produces images as if they were captured with a telephoto lens, from images captured with a wide-angle lens, will help in reducing the necessity of complex, expensive and bulky lenses on smartphones. To this end, we propose an image-to-image translation pipeline to simul…

Zero-Shot Single Image Restoration Through Controlled Perturbation of Koschmieder's Model

CVPR 2021poster

Real-world image degradation due to light scattering can be described based on the Koschmieder's model. Training deep models to restore such degraded images is challenging as real-world paired data is scarcely available and synthetic paired data may suffer from domain-shift issues. In this paper, a…

Maximally Separated Averages Prediction for High Fidelity Reversible Data Hiding

ICASSP 2019accepted

Recently pixel pairing and pixel sorting/selection have been used in prediction-error expansion based reversible data hiding schemes to generate low entropy prediction-error histograms (PEH) necessary for achieving high fidelity. Such schemes generally use the four-neighbor average rhombus predictor…
