Definition

Noise reduction refers to the techniques and methods used to minimize unwanted disturbances or random variations in signals, especially in the context of optical systems. It plays a critical role in enhancing the quality of data captured in pattern recognition and machine vision by ensuring that the relevant features are clearly distinguished from irrelevant noise, leading to more accurate recognition and processing results.
