Abstract
MAGIC proposes a training-free post-hoc compressor for efficient visual document retrieval that optimizes patch usage through a two-marginal entropic optimal-transport formulation.
Reality Card
Core Claim
MAGIC consistently outperforms strong post-hoc compressors across various benchmarks, particularly in aggressive-compression scenarios.
Method / Result
MAGIC achieves significant performance improvements in retrieval efficiency, especially under aggressive compression conditions.
Limitations
The method's effectiveness may vary based on specific retrieval backbones and benchmarks used.
