Abstract
A visual query system, and associated method and computer program product enhance and accelerate content-based querying, and present a new image similarity measure using known or available software applications and hardware components of video compression systems. The present system encodes images as consecutive frames in a video sequence and uses the ratio between the file length of the compressed sequence and the original file length as a distance measure. The system considers the compression ratio to be an estimate of the entropy of the combined images, which can be used to estimate the amount of new information introduced from one image to the other.
