ABSTRACT

Images whether from visible spectrum, photometric cameras, or other sensors are often a key and primary source of data in distributed sensor networks. As such it is important to understand images and to effectively manipulate them. The common use of images in distributed sensor networks may be because of our own heavy reliance on images as human beings. As the old adage says: “an image is worth a thousand words.” Prominence of images in sensor networks may also be due to the fact that there are many kinds of images not just those formed in the visual spectrum but also, infrared, multispectral, and sonar images. This chapter will give the reader an understanding of images from creation through manipulation and present applications of images and image processing in sensor networks.
