Abstract

New high-resolution sensors produce very large data sets and associated images requiring large bandwidths or extended times to transmit. Other techniques have been proposed to compress and sort an image to send the most significant portions of the image first, allowing the user to choose the amount of compression applied based on transmission time; but they transmit the image as a whole; Many users are interested in only portions of the image. This case is better served by a transmission method with capabilities to browse the image at low resolution to first pick the portion of interest, followed by transmission of only the portion of interest. The image is decomposed using wavelet multiresolution decomposition; and stored as an increasing succession of resolutions, each building on the resolution before it. This provides a framework to allow selecting only data required to reconstruct the portion of interest.
