# **docscopeOCR-7B-050425-exp**
|
||||
|
||||
> The **docscopeOCR-7B-050425-exp** model is a fine-tuned version of **Qwen/Qwen2.5-VL-7B-Instruct**, 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 top of the Qwen2.5-VL architecture, this model significantly improves document comprehension, structured data extraction, and visual reasoning across diverse input formats.
|
||||
|
||||
# Key Enhancements
|
||||
|
||||
* **Advanced Document-Level OCR**: Capable of extracting structured content from complex, multi-page documents such as 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.

# Quick Start with Transformers
|
||||
|
||||
```python
|
||||
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")
|
||||
|
||||
messages = [

],

text = processor.apply_chat_template(
|
||||
messages, tokenize=False, add_generation_prompt=True
|
||||
)
|
||||
image_inputs, video_inputs = process_vision_info(messages)
|

inputs = processor(

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
|

)
|

# 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.
