- Abstract
-
In this paper, we study the tradeoffs involved in choosing the bit allocation
in a multiresolution remote image retrieval system. Such a system
uses a multiresolution image coding scheme so that a user accessing
the database will first see a coarse version of the images and will
be able to accept or discard a given image faster, without needing to
receive all the image data.
We formalize the problem of choosing the bit allocation
(e.g., in the two resolution case, how many bits should be given to
the coarse image and the additional information, respectively?)
so that the overall delay in the query is minimized.
We provide analytical methods to find the optimal solution under
different configurations and show how a good choice of the
bit allocation results in a significant reduction of the
overall delay in the query (by up to a factor of two in some cases).
