[Research into estimating lumen center of dark region in colon image via cubic B-spline wavelet].
In this paper, a new method is presented to detect the edge of a colonscope image using cublic B-spline wavelet. This method can make up for the shortcoming of traditional method, resulting from blue dark area in colonscope image through estimating the circle centers. These estimated circle centers which have arc-shaped edge lines are weighted to obtained the lumen centers. This center is used to navigate colon endoscope in colonscopic operation.
