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.
