Where Does Texture Evidence Live in SAM? Features, Proposal Masks, and Texture Segmentation

arXiv:2606.14755v1 Announce Type: cross Abstract: Texture segmentation stresses foundation segmentation because meaningful regions are defined by material or repeated appearance rather than object identity. Segment Anything Models (SAMs) often fail by default on such texture-defined partitions, but this failure is ambiguous: the texture evidence may be absent, missing from the proposal bank, or present but selected or assembled incorrectly by an object-centric readout. We ask what texture-relevant evidence is already preserved in frozen SAM before adaptation. We study two frozen evidence space

Why this matters
Why now

The proliferation of foundational segmentation models like SAM has led researchers to investigate their limitations and latent capabilities, particularly in nuanced segmentation tasks such as texture recognition.

Why it’s important

Understanding how models like SAM process texture is crucial for developing more robust and general-purpose AI vision systems, impacting applications from robotics to medical imaging where material properties are key.

What changes

This research reveals that frozen SAMs may already contain relevant texture evidence, suggesting that fine-tuning rather than complete architectural redesign could unlock more sophisticated segmentation behaviors.
