Speaking of intelligent image processing algorithms, I encourage you to check out SmartDeblur, a Windows-based utility developed by Vladimir Yuzhikov that's intended for the restoration of defocused and blurred images. The developer writes:
Main functions:
- High speed. Processing of an image with the size of 2048*1500 pixels takes about 300ms in the Preview mode (when adjustment sliders can move). But high-quality processing may take a few minutes
- Real-time parameters changes applying (without any preview button)
- Full resolution processing (without small preview window)
- Deep tuning of kernel parameters
- Easy and friendly user interface
- Help screen with image example
- Deconvolution methods: Wiener, Tikhonov, Total Variation prior
Yuzhikov also provides a detailed two-part descriptive article on the theory and practice behind SmartDeblur's operation. As ExtremeTech's Bill Howard notes in a blog post describing the program:
Basically, the blurred bits in an image follow patterns that can be traced backwards mathematically. Deliberately blurred signs, serial numbers, and licenses can be adjusted enough to make them legible again.
