Abstract

The use of thumbnails (i.e., miniatures) in the user-interface of image databases allows searching and selection of images without the need for naming policies. Treating parent images prior to reduction with edge-detecting smoothing, lossy image compression, or static codebook compression resulted in thumbnails where the distortion caused by reduction was lessened. An experiment assessing these techniques found resulting thumbnails could be recognised more quickly and accurately than thumbnails of the same parent images that had been reduced without treatment. This pretreatment in thumbnail creation is offered as an improvement.
