Data Extraction Basics for Docs and Images with OCR and NER

Master Smart Data Extraction from PDF and Images with Python, Pandas, OCR, Tesseract, PyTesseract, OpenCV, Spacy, and NER

Gain a competitive edge in the world of computer vision by learning how to extract data from PDFs and images intelligently. In this comprehensive course, you’ll learn how to use a variety of powerful tools and techniques, including:

• Python: A versatile and widely used programming language for data science and machine learning

• Pandas: A powerful library for data manipulation and analysis

• OCR: Optical character recognition, used to convert images of text into machine-readable text

• Tesseract: A popular open-source OCR engine

• PyTesseract: A Python wrapper for Tesseract

• OpenCV: A computer vision library

• Spacy: A natural language processing (NLP) library

• NER: Named entity recognition, used to identify and classify named entities in text

You’ll also learn how to build a common pipeline for data extraction from different types of input documents, including structured PDF documents, scanned PDF documents, and Word documents. By the end of the course, you’ll be able to develop robust data extraction solutions for a variety of real-world applications.

Unique Offerings:

• Code walkthrough of working pipeline which performs various operations on documents such as conversion, extraction, and labeling

• Line-by-line code walkthrough of various operations performed at different steps

• End product that you will build with us towards the end of course is in working condition and support is provided within 24 hours for any issues faced

• Detailed explanation of steps required to train Spacy for NER
