Gastroscopic Image Graph: Application to Noninvasive Multitarget Tracking under Gastroscopy

Figure 2

Workflow of registration with the graph. The black lines indicate the nodes that can be connected directly. The red solid lines indicate the matching process of reference image and moving image to seek out the most similar nodes in the graph. The red dash lines indicate the pathway search process. The target tracking result is displayed as blue region on the reference image and moving image.
