Structure over Pixels: Learning Variable-Length Visual Programs

arXiv:2605.27696v1 Announce Type: cross Abstract: Discrete visual tokenizers translate images into ordered sequences of codes, providing a natural representation for structural description of scenes. Yet existing adaptive tokenizers either require post-hoc search or select among a discrete set of pre-trained rates, rather than learning a continuous per-image sequence length coupled to the model and scene, and they typically train against pixel reconstruction, emphasizing texture rather than structure. We propose STROP, a discrete visual tokenizer architecture that forms structural scene repres

Why this matters
Why now

The paper addresses current limitations in visual tokenization, a critical component for AI's understanding and generation of complex visual data, indicating an ongoing push for more efficient and robust vision models.

Why it’s important

Improved visual tokenization that prioritizes structure over pixels can lead to more sophisticated and generalizable AI vision systems, impacting various downstream AI applications.

What changes

Visual programs will be represented with variable length and learned continuously, rather than fixed or discretely selected, enabling more adaptive and interpretable scene descriptions.
