Systems and methods for generating an inspection image of an object from radiographic imaging

A system for forming an inspection image of an object from radiographic imaging, the system comprising:

• a processing unit;
• and
• a non-transitory computer-readable medium having stored thereon program instructions executable by the processing unit for:
• forming the inspection image including scaling a feature of the object in one or more of a plurality of digital images to a common scale, the plurality of digital images including at least a first digital image of the object and a second digital image of the object, the first digital image having the feature of the object at a first scale, the first digital image having a first grain diffraction pattern at the first scale, the second digital image having the feature of the object at a second scale, the second digital image having a second grain diffraction pattern at the second scale, the second scale being different from the first scale, the second grain diffraction pattern being different from the first grain diffraction pattern, the common scale being common to both the first digital image and the second digital image after said scaling, and removing grain differences between the first grain diffraction pattern and the second grain diffraction pattern at the common scale.

• forming an inspection image from the feature of the object common to the digital images at the common scale, and without grain differences between the first grain diffraction pattern and the second grain diffraction pattern at the common scale;
• and
• inspecting the object using the inspection image.
