AN OVERVIEW OF PATTERN RECOGNITION

Abstract

The operation and design of systems that can recognize a pattern in data are the subjects of the Al research field of pattern recognition. Pattern recognition has a wide range of practical uses. These consist of fraud detection, fraud prevention, handwriting recognition, facial recognition, etc. Face recognition uses a person's face to unlock a device rather than a keyboard to enter a password. As a result, there are fewer chances that the passwords will be forgotten or leaked to an unauthorized person. Since their faces are unlikely to resemble the original user's saved face model, this also prohibits other people from using the computer. The usage of handwriting in Al is handwriting recognition, one of the most promising ways to interface with small portable computing devices like personal digital assistants. They suggested visualizing the writing process on regular paper and automatically recovering the pen trajectory from numerical tablet sequences to make this communication technique appear more natural.
