picture algorithm
Description
Specify which algorithm is applied to perform comparisons between stored baseline images and images under test.
Allowable values
exact
Perform a pixel-by-pixel comparison.
key points
Perform a keypoint detection comparison.
Default value
exact
Notes
- The exact value for the picture algorithm built-in setting (specifying the pixel-by-pixel comparison technique) applies to nearly every picture handling built-in action. The sole exception is set picture min accuracy, which does not interact with the AUT.
- The key points value for the picture algorithm built-in setting (specifying the keypoint detection technique) applies to every picture handling built-in action but two: check picture is exempt, since it always applies a pixel-by-pixel comparison, and set picture min accuracy, as mentioned, has no interaction with the AUT.
