Before medical images can be distributed online, it is necessary for
confidentiality reasons to eliminate text that appears in the image.
This paper describes TIDE (Textual Information Detection and
Elimination) system for secure medical image distribution. The
algorithm uses Daubechies' wavelets to detect and eliminate areas of
textual information within digital medical images. The system is
practical for real-world applications, processing each 512x512
image in about 10 seconds. Besides its exceptional speed, the
algorithm has demonstrated a remarkable accuracy when tested on
various types of medical images, including X-ray and CT scans.
