HeatTok Semantic Patch Cache

Precomputed .pt caches for HeatTok. Use with HEATTOK_SEMANTIC_CACHE_DIR=/path/to/cache.

Filename pattern: {image_hash}_g1_s28.pt or {image_hash}_g1_gd1_s28.pt

---

semantic_patch_cache_vrsbench

• Dataset: VRSBench (512×512)
• Caches do not store precomputed global tokens or patch orientations.
• Gaussian parameters and patch metadata are stored.
• No need to regenerate .pt files — HeatTok computes global tokens and orientations online at load time.

---

semantic_patch_cache_earthvqa

• Dataset: EarthVQA (1024×1024)
• Caches use global downsample divisor 1 (gd1).
• To use divisor 8 (gd8), no regeneration needed — global branch is rebuilt online from the image processor.

Usage

export HEATTOK_SEMANTIC_CACHE_DIR=/path/to/semantic_patch_cache_vrsbench  # or earthvqa
