Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use concentric-ring fiducials with flow-conservation detection instead of the compared marker systems | Fiducial detection under challenging synthetic conditions · Synthetic images, challenging conditions (800 images) | detections: 506; no marker out of 800 images | Helped |
| Use concentric-ring fiducials with flow-conservation detection instead of ARTKPlus, PRASAD, or RuneTag | Fiducial detection · Synthetic images, Fig. 8(a) | detection rate: 93%; 44%; 27.6%; 9% | Helped |
| Use the proposed circular fiducial system instead of PRASAD | Fiducial identification in video sequences · Video sequences | misidentification rate: 32% -> 2.8% | Helped |
| Use the proposed circular fiducial system instead of PRASAD | Fiducial detection in video sequences · Video sequences | false positive rate: 6.4% -> 0% | Helped |
| Use concentric-ring fiducials and flow-conservation detection | Imaged-center localization · Synthetic images, motion blur less than 10 pixels | median imaged-center error: less than 0.4 pixels | Helped |
| Increase motion blur magnitude | Proposed circular fiducials · Synthetic images, motion blur 0, 5, 10, and 15 pixels | detection rate: 94%, 80%, 57%, and 22% | Hurt |
