Docscopeocr 7B 050425 Exp

🚀 docscopeOCR-7B-050425-exp

The docscopeOCR-7B-050425-exp model is a fine - tuned version of Qwen/Qwen2.5-VL-7B-Instruct. It is optimized for Document - Level Optical Character Recognition (OCR), long - context vision - language understanding, and accurate image - to - text conversion with mathematical LaTeX formatting. Built on the Qwen2.5 - VL architecture, it significantly enhances document comprehension, structured data extraction, and visual reasoning across various input formats.

🚀 Quick Start

🚀 Quick Start with Transformers

from transformers import Qwen2_5_VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info

model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
    "prithivMLmods/docscopeOCR-7B-050425-exp", torch_dtype="auto", device_map="auto"
)

processor = AutoProcessor.from_pretrained("prithivMLmods/docscopeOCR-7B-050425-exp")

    {
        "role": "user",
        "content": [
            {
                "type": "image",
                "image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
            },
            {"type": "text", "text": "Describe this image."},
        ],
    }
]

text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)
image_inputs, video_inputs = process_vision_info(messages)
inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to("cuda")

generated_ids = model.generate(**inputs, max_new_tokens=128)
generated_ids_trimmed = [
    out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
print(output_text)

✨ Features

• Advanced Document - Level OCR: Can extract structured content from complex, multi - page documents like invoices, academic papers, forms, and scanned reports.
• Enhanced Long - Context Vision - Language Understanding: Designed to handle dense document layouts, long sequences of embedded text, tables, and diagrams with coherent cross - reference understanding.
• State - of - the - Art Performance Across Resolutions: Achieves competitive results on OCR and visual QA benchmarks such as DocVQA, MathVista, RealWorldQA, and MTVQA.
• Video Understanding up to 20+ minutes: Supports detailed comprehension of long - duration videos for content summarization, Q&A, and multi - modal reasoning.
• Visually - Grounded Device Interaction: Enables mobile/robotic device operation via visual inputs and text - based instructions using contextual understanding and decision - making logic.

📚 Documentation

Intended Use

This model is intended for:

• High - fidelity OCR from documents, forms, receipts, and printed or scanned materials.
• Image and document - based question answering for educational and enterprise applications.
• Extraction and LaTeX formatting of mathematical expressions from printed or handwritten content.
• Retrieval and summarization from long documents, slides, and multi - modal inputs.
• Multilingual OCR and structured content extraction for global use cases.
• Robotic or mobile automation with vision - guided contextual interaction.

Limitations

• May show degraded performance on extremely low - quality or occluded images.
• Not optimized for real - time applications on low - resource or edge devices due to computational demands.
• Variable accuracy on uncommon or low - resource languages/scripts.
• Long video processing may require substantial memory and is not optimized for streaming applications.
• Visual token settings affect performance; suboptimal configurations can impact results.
• In rare cases, outputs may contain hallucinated or contextually misaligned information.
