BluePixel: Toward Native 4K Agentic Image Editing

Instruction-driven image editing has reached native 4K, yet how such editors are trained remains undisclosed, and pretraining one from scratch is beyond most teams. The task itself compounds the difficulty: a single end-to-end editor cannot make precise parametric adjustments, match specialized experts, or interpret th...

Rethinking Omni Spatial-Frequency Representation for Efficient Face Super-Resolution

Face Super-Resolution (FSR) faces a critical challenge in balancing reconstruction quality with computational efficiency when deployed on resource-constrained devices. While existing methods leverage CNNs or transformers, they are constrained by limited receptive fields or high computational complexity. To achieve both...
