Layout Analyzer Skill

Overview

This skill enables document layout analysis using surya - an advanced document understanding system. Detect text blocks, tables, figures, headings, and determine reading order in complex documents.

How to Use

1. Provide the document image or PDF
2. Specify what layout elements to detect
3. I'll analyze the structure and return detected regions

Example prompts:

• "Analyze the layout of this document page"
• "Detect all tables and text blocks in this image"
• "Determine the reading order for this PDF page"
• "Find headings and paragraphs in this document"

Domain Knowledge

surya Fundamentals

from surya.detection import DetectionPredictor
from surya.layout import LayoutPredictor
from surya.reading_order import ReadingOrderPredictor
from PIL import Image

# Load image
image = Image.open("document.png")

# Detect layout elements
layout_predictor = LayoutPredictor()
layout_result = layout_predictor([image])

Layout Element Types

Text Detection

from surya.detection import DetectionPredictor
from PIL import Image

# Initialize detector
detector = DetectionPredictor()

# Load image
image = Image.open("document.png")

# Detect text regions
results = detector([image])

# Access results
for page_result in results:
    for bbox in page_result.bboxes:
        print(f"Text region: {bbox.bbox}")
        print(f"Confidence: {bbox.confidence}")

Layout Analysis

from surya.layout import LayoutPredictor
from PIL import Image

# Initialize layout predictor
layout_predictor = LayoutPredictor()

# Analyze layout
image = Image.open("document.png")
layout_results = layout_predictor([image])

# Process results
for page_result in layout_results:
    for element in page_result.bboxes:
        print(f"Type: {element.label}")
        print(f"Bbox: {element.bbox}")
        print(f"Confidence: {element.confidence}")

Reading Order Detection

from surya.reading_order import ReadingOrderPredictor
from surya.layout import LayoutPredictor
from PIL import Image

# Get layout first
layout_predictor = LayoutPredictor()
image = Image.open("document.png")
layout_results = layout_predictor([image])

# Determine reading order
reading_order_predictor = ReadingOrderPredictor()
order_results = reading_order_predictor([image], layout_results)

# Access ordered elements
for page_result in order_results:
    for i, element in enumerate(page_result.ordered_bboxes):
        print(f"{i+1}. {element.label}: {element.bbox}")
