Path Planning of Virtual Endoscopy Based on Image Segmentation
Fang Hongbin · Microcomputer Information · 2010
Path planning is a prerequisite task to automatically navigate with virtual camera and plays a crucial role in virtual endoscopy application. The path planning algorithm based on segmentation combines the center-line path with the image segmentation by using the result of image segmentation to reduce the complexity of path planning. The algorithm makes use of the connectivitypreserving features of sequence images and segments a series of images by applying the adaptive region growing algorithm. It stores the seed of growing region into a series of stack as the key point of the navigation plan. The navigation path is obtained after smoothing those points. Experiment results show that our algorithm is feasible and robust.
