The truck influenced magnetic field and blocked detection of available geometric landmarks.
However, since these sensors observe geometric landmarks, the localization accuracy can be easily affected by dynamic changes in its surroundings.
As the result, stable navigation could be performed even if available geometric landmarks could not be observed.
In the system, several navigation modules are executed in parallel, and they independently control the robot by using magnetic and geometric landmarks.
To solve this problem, we have proposed to use ambient geometric landmarks for compensating the robot's position (MNPC: Magnetic Navigation with Position Compensation [6]).
This is a new approach to quantifying functional integration because we use measures of movement and displacement, such as the amount the mandible translates laterally during occlusion, as opposed to conventional morphological measures, such as mandible length and geometric landmarks.
We quantified mouth morphology by recording 11 geometric landmarks of the stoma that were considered homologous, as informed by fine-structural anatomy, across Diplogastridae and outgroups (Baldwin et al., 1997; Ragsdale and Baldwin, 2010).
For each of the selected images, view plane information (short axis, apical long axis, four chamber, etc)., cardiac cycle of interest and geometric landmarks that aid in tracking the wall motion should be provided.
The proposed framework makes use of a graphical representation of the world in order to build a map consisting of qualitative constraints on the geometric relationships between landmark triplets.
Some landmarking techniques are not only based on texture, but also use geometric relations between landmarks, for instance [12 15].
