perceptual_diff(std_image,
test_image)
|
|
Run Perceptual Diff to compare a test image to a standard.
The workup requires access to the shared installation of Perceptual
Diff in /nfs/software/lib/<platform>/. It expects host-specific std
images to be located in a subdirectory of the test named
references/<hostname>/. For example, for the host
pdx-desk-l03.schrodinger.com, refeerences are expected in
stu_<testid>/references/pdx-desk-l03.schrodinger.com/.
usage: custom.perceptual_diff.perceptual_diff(std_image,
