Abstract
A surgical assistive apparatus and method to provide assistance during surgery, includes an organ boundary localization circuit that selects a test video frame from a captured sequence of video frames and derives a first global region boundary of an internal organ of interest in the selected test video frame by integration of an appearance likelihood result, a global segmentation result, and a global edge detection result associated with the internal organ of interest. A plurality of local region boundaries are determined for a plurality of local sub regions of the internal organ of interest and a second global region boundary is generated for the internal organ of interest based on the determined plurality of local region boundaries and the first global region boundary. The internal organ of interest is localized based on the generated second global region boundary.
