Abstract:
The fast growth of digitized pathology slides has
created great challenges in research on image database retrieval. The
prevalent retrieval technique involves human-supplied text annotations
to describe slide contents. These pathology images typically have
very high resolution, making it difficult to search based on image
content. In this paper, we present Pathfinder, an efficient
multiresolution region-based searching system for high-resolution
pathology image libraries. The system uses wavelets and the IRM
(Integrated Region Matching) distance. Experiments with a database of
70,000 pathology image fragments have demonstrated high retrieval
accuracy and high speed. The algorithm can be combined with our
previously developed wavelet-based progressive pathology image
transmission and browsing algorithm and is expandable for medical
image databases.
