PARSeq — Scene Text Recognition (GGUF)

GGUF conversions of PARSeq (ECCV 2022) for use with CrispEmbed.

PARSeq is a scene text recognition model that reads text from natural images (signs, labels, documents). It recognizes 94 printable ASCII characters (digits, letters, punctuation).

Architecture

• Encoder: 12-layer pre-LN ViT (patch 4×8, input 32×128 RGB, 128 tokens, GELU FFN)
• Decoder: 1-layer two-stream Transformer (XLNet-style position queries + context self-attention, then cross-attention to encoder memory)
• Head: Linear → 95 classes (94 printable ASCII chars + EOS)
• Inference: Autoregressive greedy decode (max 25 characters)

Variants

File	Variant	Params	Size	Notes
parseq-f32.gguf	Base	24M	91 MB	Full precision
parseq-q8_0.gguf	Base	24M	24 MB	Best quantized
parseq-q4_k.gguf	Base	24M	13 MB	Smallest base
parseq-tiny-f16.gguf	Tiny	6M	12 MB	Half precision
parseq-tiny-q8_0.gguf	Tiny	6M	6 MB	Smallest overall

All quantization levels produce identical output on test images.

Usage

# CLI
crispembed -m parseq-q8_0.gguf --ocr image.png

# Auto-download
crispembed -m parseq --auto-download --ocr image.png

from crispembed import CrispMathOcr
ocr = CrispMathOcr("parseq-q8_0.gguf")
text = ocr.recognize("sign.png")
