SharpnessCheck 1.0.0

I asked ChatGPT if there was any software component that could help determine how sharp an image was. It pointed me to Accord.NET, or more specifically Accord.Imaging. My interest was piqued,so I decided to write a tool that used this component. And SharpnessCheck is the result.

My goal was to find the least sharp cover scans, so I could scan them - hopefully better - myself. So, did SharpnessCheck fulfill my dreams? Eh, not quite. Accord.Imaging's routines for determining sharpness was - I presume - meant for photographs. Cover scans don't have quite the same properties as regular photographs, so that might explain why the results are not quite what you would expect.

Still, I don't see any reason why I shouldn't share this tool, so you can play with it yourselves. On my initial tests it was quite slow. Scanning some 9000 images took about 14 minutes. Then I decided to go parallel. That was a new experience for me. This lets me use all the CPU cores for processing the image checks. Did that make a difference? You bet! It reduced the time from 14 minutes to 1 1/2. Now, the result will of course depend on your CPU. Mine is an Intel i5 with 6 cores, allowing 12 parallel tasks to run.

See the help file for details!



PS: Just so you know, this will hog your CPU quite a bit.
