Fig. 3: 3D point object tracking using focal stack data for three different types of point objects.
From: Neural network based 3D tracking with a graphene transparent focal stack imaging system
a, b Tracking results for single point object (only 10 test samples are shown). Results are based on images captured with the graphene photodetector arrays. c, d Tracking results for three-points objects (only 4 test samples are shown). Results are based on data synthesized from multi-focal-plane CMOS images (downsampled to 9 × 9) of single point source. e Tracking results for rotating two-point objects on one testing trajectory. The object is rotating counter-clockwise (viewed from left) while moving from \(z=-10{\rm{mm}}\) to \(z=10{\rm{mm}}\). Results are based on data synthesized from single point source images captured with graphene photodetector arrays.
