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
