Sentence examples for motion contrast techniques from inspiring English sources

A general disadvantage of highly sensitive motion contrast techniques is the decorrelation signal appearing below vessels that reduce the axial vessel segmentation.

It has also been proposed a motion contrast technique to image a larger range of velocities [ 19].

The phase-variance based motion contrast technique for Fourier-domain OCT (Fd-OCT) [ 9] has been implemented successfully in visualizing vasculature of the zebrafish [ 10], ocular circulation of the mouse [ 11], and human retinal vasculature [ 12].

(3) Motion contrast across the object boundary [26].

The motion contrast of video sequence is measured by motion entropy.

Temporal motion contrast neurons that respond strongly for changes from low motion energy to high motion energy indicate disocclusion regions, temporal motion contrast neurons that detect changes from high to low motion energy indicate occlusions (Fig. 5).
