A Low-complexity Intestinal Lumen Detection Method for Wireless Endoscopy Images

摘要

In this paper, an intestinal lumen detection method suitable for hardware design is proposed for the locomotive capsule or intelligent Micro-Ball endoscopy. In order to get low complexity as well as relatively high detection precision, a global threshold segmentation algorithm for non-full-shrink lumen and texture based algorithm for full-shrink lumen are proposed. Furthermore, only the red channel of the original Bayer-format image is used in the two algorithms. The computational complexity of the lumen detection method is also given. Experimental results show this method can provide 99.3% precision and 99.0% sensitivity.
