Pdf Squirrel

Overview

The Pdf Squirrel project is designed to facilitate the detection and manipulation of graphical and text blocks in images. This repository includes scripts for finding blocks in images, converting PDF files to images, normalizing and processing document images, applying blurs to specific sections, and drawing rectangles around detected sentences in images.

Features

• Block Detection: Identify and outline blocks in images.
• PDF to Image Conversion: Convert PDF documents into images.
• Image Normalization: Process images to enhance text visibility and remove graphical elements.
• Blur Effects: Apply blur effects to text blocks to visually separate them.
• Sentence Detection: Draw rectangles around detected text sentences.

Installation
