Apple unveils LensVLM for improved VLM accuracy with compressed text

Apple researchers have developed LensVLM, a new framework and post-training method designed to improve the accuracy of Vision Language Models (VLMs) when processing compressed text images. LensVLM works by selectively expanding only the relevant parts of a compressed image to its uncompressed form, rather than processing the entire image at a lower resolution. This approach allows VLMs to maintain high accuracy even at significant compression levels, outperforming other compression methods on text QA benchmarks and generalizing to multimodal document and code understanding tasks.

    LensVLM: Selective Context Expansion for Compressed Visual Representation of Text

    Vision Language Models (VLMs) offer the exciting possibility of processing text as rendered images, bypassing the need for tokenizing the text into long token sequences. Since VLM image encoders map fixed-size images to a fixed number of visual tokens, varying rendering resolutio…
