    Study Notes

    Definition and Overview

    • Handwriting recognition is the ability of a computer to interpret and understand handwritten input
    • Also known as handwritten character recognition (HCR) or offline handwriting recognition
    • Involves the automatic recognition of handwritten characters, words, or phrases from an image or digital representation

    Types of Handwriting Recognition

    • Online Handwriting Recognition: recognizes handwritten input in real-time, often used in touchscreen devices and digital pens
    • Offline Handwriting Recognition: recognizes handwritten input from a static image, often used in document scanning and image processing

    Techniques Used

    • Feature Extraction: extracting relevant features from handwritten input, such as shape, size, and orientation
    • Pattern Recognition: identifying patterns in handwritten input using machine learning algorithms
    • Neural Networks: using artificial neural networks to recognize and classify handwritten characters

    Applications

    • Document Scanning and Archiving: recognizing handwritten text in documents, such as historical archives and legal documents
    • Form Processing: extracting handwritten information from forms, such as surveys and applications
    • Mobile Devices: enabling handwriting recognition on touchscreen devices, such as smartphones and tablets
    • Healthcare: recognizing handwritten medical notes and prescriptions

    Challenges

    • Variability in Handwriting: different writing styles, sizes, and orientations can make recognition challenging
    • Noise and Distortion: dealing with noisy or distorted images of handwritten input
    • Language and Script: recognizing handwritten text in different languages and scripts
