Feature Extraction Methods in Machine Vision Systems

摘要

The machine vision systems have not only to "see" where an object is placed and how it is placed but sometimes also to identify the object. A visual system can perform the following functions: the image acquisition and analysis, the recognition of an object or objects within an object groups. In machine vision systems, visual features such as shape, color and texture are extracted to characterize images. Each of the features is represented using one or more feature descriptors. The feature extraction methods for this applications are discussed.
