Book Description

Digital imaging is essential to many industries, such as remote sensing, entertainment, defense, and biotechnology, and many processing techniques have been developed over time. This Field Guide serves as a resource for commonly used image-processing concepts and tools; with this foundation, readers will better understand how to apply these tools to various problems encountered in the field. Topics include filtering, time-frequency-domain processing, and image compression, morphology, and restoration.
