During the SCAPE Scenario Workshop we (AIT) have presernted and discussed the current state of the image comparison tool. The tool facilitates solutions for the following QA problems:
- Assembling collections
- Avoiding duplicates
- Checking collections
- Missing images
- Make a selection of objects that need to be looked at (duplicates, old/new versions)
- Analyze accuracy of collection (possible duplicates, broken files, files with translations, wrong cropping, rotation)
- Compare 2 images independent from format in different complexity level (histogram, pixel wise)
Digital Preservation issues associated with image comparison tools are:
- Make a selection of objects that need to be looked at (duplicates, old/new versions))
- Analyze accuracy of collection (possible duplicates, broken files, files with translations, wrong croppings, rotation)
- Compare 2 images independent from format in different complexity level (histogram, pixel wise)
- Detect files in question (possibly broken) on one collection & analyze them using impact tools for correction
- Using CUDA for parallelisation of collection analysis
