IM-LUT: Interpolation Mixing Look-Up Tables for Image Super-Resolution

Can LUTs alone enable arbitrary-scale super-resolution?

Idea

Learn interpolation mixing weights and convert them into LUTs for efficient arbitrary-scale super-resolution.

Outcome

Enables continuous-scale super-resolution while retaining efficient LUT-based inference.

FDCNet: Feature Drift Compensation Network for Class-Incremental Weakly Supervised Object Localization

Can weakly supervised localization learn new classes without forgetting previously learned localization knowledge?

Idea

Compensate feature drift caused by class-incremental learning to preserve localization capability across sequential tasks.

Outcome

Maintains localization knowledge while progressively learning new object classes.
