Abstract

We present a method for displaying reduced resolution versions of images in order to quickly browse through a large archive of digital images. The browse image requires only one kilobyte and, thus, can be stored in the header of the image file and can be quickly retrieved from that disk file and transferred over a network for viewing on a high resolution image display. This method differs from past research on progressive transmission of reduced resolution images. Our browse image, the displayed image, and the original image are all of different spatial and color resolutions. Typical values would be a 32x32 by 8 bit encoded color browse image from a 512x512 by 24 bit full color original to be displayed at 128x128 full color. We analyze and compare several methods of compression and decompression of digital images reporting their performance on both isolated workstations and over the network.
