| Member name | Value | Description | |
|---|---|---|---|
| Standard | 0 | The standard algorithm used for registering and labeling the features. This algorithm is fast and works well on clean images but may fail on images better handled by Exhaustive mode. | |
| Exhaustive | 1 |
An exhaustive algorithm used for registering and labeling the
features. This algorithm uses an exhaustive strategy and is
more robust than the standard algorithm, although it may take
longer to run.
This exhaustive algorithm was specifically designed to tolerate: contrast variations, low contrast images, image blurring, defects on the plate, and highlights. In addition, the exhaustive algorithm will often return slightly different positions (differing by less than 0.01 pel in most cases) for the found features than the Standard algorithm. | |
| ExhaustiveMultiRegion | 2 | Similar to Exhaustive, but it returns feature correspondences from all contiguous regions of checkerboard features in which a DataMatrix was successfully decoded. | |
| Efficient | 3 | An efficient algorithm: This algorithm uses an efficient strategy which is much faster than the exhaustive algorithm with comparable robustness, accuracy, and repeatability. The efficient algorithm requires less memory in most cases of contrast variations and the other image artifacts. The efficient algorithm is more suitable for time critical applications that require checker feature extraction. | |
| EfficientMultiRegion | 4 | Similar to ExhaustiveMultiRegion, but using the Efficient algorithm instead of the Exhaustive algorithm. In other words, EfficientMultiRegion can handle disconnected features if each group is near a DataMatrix code, similar to how ExhaustiveMultiRegion can handle disconnected features. |
