In order to model the actual object motion, instead of using linear interpolation between key frames, we use cubic spline interpolation, as can be seen in Fig. 13.
Due to possible large illumination and reflection changes between different frames, we use image comparison method Normalized Correlation Coefficient (8) that is less illumination independent.
Instead of considering absolute independence between AV frames, we consider a conditional independence assumption that is the coherency of an AV frame can be estimated independent of other frames given a context of a few (K) neighbor frames.
In order to compute robust threshold of correlation between neighboring frames, we collected CCE videos from nine people and extracted seven segments (50 frames each) from each video, which are marked by gastroenterologist as suspected region for different types of pathology.
Assuming the instantaneous center of rotation remains constant during the interval between two frames, we can use this circularity of trajectory to predict the new ground plane position of a feature with known position in the previous frame, for every combination of steering angle and velocity.
"Between frames we carefully move around the atoms to their new positions, and take another image," he told BBC News.
Since we know the time between frames, we can calculate the range of gradients, and we can remove the invalid gradients.
Between two consecutive frames we have different inter frame spacing (IFS) intervals, which guarantee different types of priority.
For the calculation of the primary motion parameters (horizontal and vertical motion as well as rotation of the head between two consecutive frames) we calculated mean values for each trace point from the 10 repeated measurements.
Using TBlastX to establish homology between open reading frames, we identified 28,182 regions from 13 species syntenic to one of 5,957 intergenic regions in S. cerevisiae.
