End-to-End Learned Image Coding: From Rate-Distortion Optimization to Practical Deployment

End-to-end learned image coding (LIC) has achieved substantial improvements in rate--distortion (R--D) performance, yet practical deployment requires addressing a broader set of system-level constraints. This article provides a deployment-oriented review of LIC, with particular attention to the transition from high-per...

ReX-Shot: Single-Image Rephotography via Geometry- and Camera-Grounded Generation

ReX-Shot is the first unified framework to jointly control viewpoint, focal length, and parameterized photographic effects from a single image, and Experiments show that ReX-Shot outperforms representative baselines across all three controls while enabling near-real-time interactive rephotography.

Hadamard-Domain Model Quantization for Learned Image Coding

Hadamard-Transform-domain Quantization (HaTQ), which uses orthogonal Hadamard reparameterization before quantization to redistribute weight and activation responses in the original domain across channels, and is compatible with integer-only execution.
